Cleaning CA Glue off your bushings

I don’t know why this was so hard to get information on when I first started, but it was! So writing a short post dedicated to the topic.

Whether you use non-stick bushings or not, you will end up with CA glue all over your bushings — the main point of the non-stick bushings it to make it easy to get the bushings off your CA-finished pen, rather than to prevent it from fully sticking to the bushings.

Applying wax to the bushings ahead of time can help your pen separate after finishing (I use a caranuba wax, though I suspect any will work), but there’s still the question of getting the CA glue off the bushings after it builds up.

I have a bottle of pure acetone and several sets of non-stick bushings. After enough of them get enough CA built up, I just pour some acetone (same substance as in many nail polish removers) into a small bowl, dump my bushings in there, and then come back later.

Critically important warning: the acetone does not make the CA glue go away, it just temporarily dissolves it. If you fish your bushings out and just dump the acetone down your drain, the second it comes into contact with water that CA glue will turn right back into CA glue — in a stringy, big, sticky, drain-clogging mess.

I tend to fish my bushings out with a skewer, set them aside, add some water to the bowl to solidify the CA, fish it out and dump it, and then add more water to see if there’s any CA left. When I can add water to the bowl without any strings appearing, it’s safe.

I haven’t personally tried nail polish remover (I don’t use nail polish), but I suspect it will work as long as it’s acetone.

Also please read the warnings on the bottle of acetone: it’s not going to kill you, but it’s highly flammable, you don’t want it in your eyes or if you have a cut on your hands, etc.

Mercury also makes a “CA dissolver” product that I have not tried, and other manufacturers may as well.

Here’s the bottle of acetone that I bought, though there’s nothing particularly special about it: Eternal Professional Nail Polish Remover – 100% Pure Acetone

CA Glue: BSI Odorless vs Mercury Flex

Previously my recommendation was BSI odorless, because it was working sufficiently well for me, and I appreciated the “odorless” aspect, even though the same personal protective equipment is still recommended, because it reduced the chance of problems.

Recently however I got a chance to try Mercury flex, and I am now a committed Mercury fan.

Caveat: this is not a perfect comparison: technically I should compare the BSI odorless to mercury odorless, and BSI flex to mercury flex. But I don’t have the time or money to do that right now, so I’ll report on what I’ve seen so far and write more if I get a chance to do more comparisons in the future.

Bob Smith Industries (SBI) Super-gold

This CA glue works great for sure. I got good results with it, appreciated the low-odor aspects, and it comes highly recommended by experienced pen-makers like Toni Street.

But even with my technique improving in other ways, I was still having a lot of issues with bumpy CA application that I wasn’t able to get past. I suspect this is in part because I am working somewhat slapdash out of my art studio, rather than in a proper shop: stuff is clamped to the edge of my craft table and for a long time I was using just a hand drill with a mandrel attached to it.

I also found I just wasn’t comfortable without using a respirator: after doing more than one pen in a row I could feel some tightness in my chest, as it’s hard to perfectly ventilate a craft room, and I didn’t want to risk long-term health issues. So I wasn’t getting as much of a benefit off odorless as I hoped.

One nice thing about Super-Gold is that it does dry pretty fast, which BSI notes is one of the features — but I believe it was also part of my problem, along with the technique I’d come up with for applying it in my make-shift setup: I was spraying the barrel with accelerator, which was helpful, but also meant some of it hardened instantly on application, making bumps more likely.

I changed my technique to use accelerator afterwards and it was smoother, but I was still getting more bumps then I liked, and my sanding time was long as a result (and sometimes I’d have to go back and re-apply CA because I’d had to sand so far to get rid of a bump that I went right down to the clay and had to start over again.)

Mercury Flex

When discussing my lumps and bumps, a friend encouraged I try Mercury flex — it’s not odorless, but it’s thin, and also had a great track record when working on polymer clay pens.

I’ve found that the slower cure time is making it much easier to smooth everything and reduced my CA sanding time by almost half per pen. It’s a bit more likely, with the thin CA, for it to get thrown off the pen and land on clothes/items around me, but using less each time and reducing the rate of rotation has helped a lot there.

The downside is I am also having a few more issues with the odor: when I do more than one pen in a session, I’ve started to notice a bit of dry eye that may indicate some issues with the odors affecting my eyes also. I bought some goggles with a seal online and it’s reduced the problems there though the combination of the two masks is awkward and affects the seal. (Unfortunately a full-face mask with a respirator, which is the best, is quite expensive.)

I’ve continued to use the accelerator afterwards, and am getting much smoother results with that technique and the Mercury CA.

The one problem I still have is I’m now getting grooves around the pen body, I suspect due to the fact that I’m applying the CA with strips of deli paper, and it’s curving up in as I remove the paper, since they occur in the same spots repeatedly. I am considering switching to cling wrap as a replacement, and will write more if it’s more effective.

Troubleshooting Pen Making: CA Glue

Making a pen is a more technical process than much of what we do with polymer clay, so there are a lot of places where things can go wrong, particularly when you combine different materials and equipment.

This article is much more complete thanks to the second half of this article on Toni Street’s website that discusses troubleshooting common problems. I’ve written it with my own troubleshooting, but my troubleshooting was definitely helped by what I learned initially from her.

CA glue cracks a few hours after you finish

This happened when I made my first pen using a poor quality CA accelerator or glue. Read the article on CA glue basics for more help.

It can also happen if you generate too much heat in the curing process: for me this was buffing too aggressively.

Toni notes that it could be due to the glue curing too fast. See her page for more tips on that. This hasn’t been an issue for me yet.

CA is white or cloudy in spots

Your pen wasn’t dry, or you used too much accelerator or sprayed it too closely to the pen blank. This can reportedly also happen in very humid climates due to the excess water in the air.

Cracks form weeks/months later

Toni notes that this is usually due to using a non-flex CA. See the article on CA glue basics for more help.

Part of your pen isn’t shiny despite you applying CA everywhere

You sanded below your CA finish and exposed the polymer clay below it. This has happened to me when I tried to sand two barrels at once by going back and forth across both of them: I over-sanded the ends of the barrels in the middle and under-sanded the ones at the far ends, resulting in bare plastic in the middle.

The good news is the solution is simple: just start over applying more CA. You do not need to re-sand all the CA off, just make sure you thoroughly clean and dry the barrels so there’s no dust, water, or oil on them before starting again.

Your CA is very bumpy

You applied too much CA too quickly and it clumped — this will not get better with more CA, you have to sand it back down before you continue.

Check every coat or two when applying it to catch this problem early before it gets worse. You can sand in the middle of your coats and continue applying CA afterwards, just make sure it’s dust- and water-free before continuing.

Your bushings are stuck to your pen after applying CA

If it’s just a thin coat of CA between the bushing and the pen, just twist them apart. If it’s a lot of CA, you applied too much CA or your pen blank was over the bushing height before you began applying the CA, and you need to sand it down more before adding the CA.

There are more tips in the article on finishing a pen with CA glue.

Your CA finish cracked when you pressed your pen together

You didn’t sand off excess CA after removing it from the bushings. See the article on finishing a pen with CA glue.

Your CA finish has pits in it/won’t get smooth

You didn’t apply enough CA to fill in the pits in your original clay finish. Consider sanding more and/or applying more or thicker CA. Medium CA will do a better job filling in pits, which is why I always end with at least 1-2 coats.

Basic pen making terms

Like any other activity, pen makers have their own specialized terminology that can be confusing when you first start.

Bands

The piece of metal that goes between two parts of the pen — e.g., where a twist pen twists.

You can get specialized bands engraved with various designs that fit specific pen kits; make sure you get one that fits your pen kit.

Barrel trimmer

Used to trim down a blank to exact size after cutting it. Not necessary for making polymer clay pens.

Blanks

Blanks are blocks of wood or acrylic that pen turners spin on a lathe and use woodworking tools to cut down to size. Sometimes polymer clay artists call their finished barrels “blanks” as well, especially if they’re selling just the barrels instead of the finished pens.

Bushings

Bushings are small metal tubes that you use on each end of your barrel to show what height you want the end of the barrel to be. If you want, the barrel can be different heights between them, but for a smooth pen feel, each end should match the bushing for that end.

Some kits have different bushings for each end, so pay attention to your kit’s directions and make sure you create your barrel correctly and then orient it correctly when assembling the pen.

Different pens have different kits, so pay attention to what you need for which kit and consider storing your bushings in bags that identify which kit(s) they are used with.

CA Accelerator

Accelerator is sprayed on to your CA after each layer if you want it to set faster.

CA Glue

Cyanoacrylate Glue makes a very durable finish for pens, including polymer clay pens. While superglue is technically a brand of CA glue, it is not a good choice for finishing pens.

Cap

The top of a pen.

Chisels

Used by pen turners for reducing a blank to appropriate size. Not used when making polymer clay pens unless you are turning them (which most people don’t.)

Clips

The clip is the part of the pen that attaches it to your pocket or notebook. Many pen kits that include clips can be assembled without the clip if you prefer a clip-less pen.

You can also buy specialized clips with various designs and engravings for different pen kits, just make sure you get one made for your pen kit.

Drill bits, chucks, etc.

Used by pen turners for drilling out a blank. Not necessary when making polymer clay pens.

IAP

The International Association of Pen Turners: https://www.penturners.org/

Lathe

Woodturners use lathes to turn their pens. Since we do not have to turn our pens, you can skip buying a lathe and either sand by hand or use something like a drill or Foredom.

Mandrel

A mandrel is just a rod you use to assemble the pen.

When you are turning a wooden pen, or finishing any pen (including polymer clay), you want a threaded mandrel so you can use nuts to tighten your barrels against the bushings so they don’t spin when you try to turn them or sand them.

You can assemble your own mandrel or buy one.

Pen Kit

A pen kit contains the hardware necessary to assemble a pen. It will have the ink, the tip, the appropriate mechanism (twist or click), and some brass barrels you will put clay around.

It will not include bushings, you will need to buy those separately if you want them.

Pen Press

A specialized piece of equipment that makes it easier to assemble a pen kit. You can also use a vice, though they can be harder to keep the pen kit in proper alignment, and if you don’t already have one they can cost almost as much as buying a pen press.

Pen Tube Insertion Tool

Not required for polymer clay pens, it’s used by pen turners who are drilling out blanks and need to insert the tube into the drilled blank.

Refills

Pen kits are usually designed like normal pens you purchase are and you can replace the ink when it is used up. Make sure you look up your kit and take a note of what refills it takes.

Tip

The point of a pen that the ink cartridge comes out of so you can write with it.

Tubes

Pen kits come with brass tubes that you will apply polymer clay to, to create the decorated barrels for your final kit. Different kits use different length tubes and sometimes a kit with two tubes has two different sizes or diameters for those tubes.

You can also just buy tubes on their own without the kits, which is cheaper and a good option if you want to experiment more or sell polymer clay “blanks” rather than finished pens.

If you haven’t yet applied CA glue, you can always peel your clay off a tube and re-use the tube if you didn’t like the pen you made, even after baking. If it doesn’t come off the tube by picking at it with your fingers, you can use a blade to slice into the clay and peel it off.

If you have already applied glue you could sand it down enough to be able to peel off the clay, but tubes are cheap enough (and can be bought on their own, without the pen kits) that that may not be worth the time and effort.

Translating Pen Turning Terms into Polymer Clay

Much of the information online about pen turning is confusing because it’s difficult to sort out what actually applies to making polymer clay pens and what doesn’t.

Do I need a lathe?

No. I have posts here about how to use a drill to finish pens, and you can even just sand them by hand if you want. They are linked off my page on Making Pens with Polymer Clay.

Do I need to buy blanks?

No, you will form your clay right on the brass tubes that come with a pen kit. All you need to do is buy a kit (search “pen kits” in your favorite search engine to find many sources for buying them.)

If you just want to practice, or want to make “blanks” (barrels) to sell, you can buy tubes separately.

Do I need to drill out the center? Superglue the tube to the clay?

No, that’s because woodturners get solid blocks of wood or acrylic that they need to drill out and then superglue (aka CA glue) the tube in. Since we form our “blanks” right on brass barrels, there’s no need to drill them out.

Do I need to buy wood turning tools like a chisel?

No, not unless you are planning on building a solid clay blank and turning it like it were wood. Most polymer clay pens are formed close to their final shape and size, and you can use your standard sanding tools to sand them down and smooth them.

Do I need a mandrel? Bushings?

No, you can make your own mandrel and while bushings are helpful, they’re not required. See my article on the minimum equipment necessary to make a pen for information on how to create your own tools from cheap hardware store components.

Do I need specialized sanding or polishing equipment?

No, you can use what you already use for polymer clay. Just realize that, like jewelry, polymer clay pens will be handled up close so you need to sand and polish them very well and, unlike jewelry, it’s very hard to use resin on them.

You may want to read my article on optional tools that make penmaking easier and higher quality, which discusses some specific sanding and polishing options.

Do I need a pen kit?

Eventually you may like one, but you can start using disposable Bics (or potentially even other brands, just check that the barrel (without the ink cartridge) can stand up to your oven at your clay’s temperature for your normal baking time. Bic Clic Stic, Bic Soft Feel Retractable, and Bic Round Stic are all pens I have heard will work, though it’s always worth double-checking yourself in case the manufacturer changed the formula.

You will need to pull the pens apart, cover the barrel (remove the ink cartridge!), bake, sand/finish, and then put the pen back together.

Do I need a pen press?

Technically no, though if you bought one piece of specialized equipment, I’d recommend it be a simple pen press. There’s more information in my article on the minimum equipment necessary to make a pen.

Do I need to use some specialized finish like CA glue (superglue)?

Definitely not! Melanie Rollens is a fabulous cane and pen maker and doesn’t finish with anything other than sanding and buffing.

That said, I personally prefer a CA finish, and have written a bunch of articles linked off my page on Making Pens with Polymer Clay to try to de-mystify the process for polymer clay artists.

Quality of life equipment upgrades for pen making

Got the basics purchased but interested in some ways to make penmaking easier by spending a bit of money? Here are some of my favorite tools.

I do not get any commission from any links on my site, not even from Amazon. I am just sharing things I’ve found effective and helpful.

Kits and Tubes App

The International Association of Pen Turners has a database of bushings and tube sizes, but they also provide it in app form for iOS for $0.99: IAP Bushings & Tubes Reference. There’s also an Android version I haven’t personally used.

It’s definitely not required, but I’ve found it a useful reference and for $0.99 it’s a nice way to thank them for keeping the database up to date as well.

They will be updating the database again soon, according to their website, so while you may find some missing kits (I haven’t yet, but I’m using pretty standard kits) an update is supposedly coming.

Cutters

I used these PolyClay Tube Cutters from Penn State on every pen I make and find them well worth the $7 I paid for the set.

There are different sizes that will allow you to quickly and easily cut clay to fit (with no overlap) around the most popular pen barrel sizes: 7mm, 8mm, 3/8 in., 27/64 in. and 10mm.

They’re extra long, so they work with a variety of tube lengths, and you can easily trim the ends off your barrel after wrapping it.

When I’m doing a kaleidoscope I don’t use them, since I want it to tile perfectly (then I use my graph paper templates), but since I often like to work on a base layer of clay, they’re perfect for getting an easy base layer in place rolled out on the very thinnest level on my pasta machine.

PolyClay Mandrel

Also from Penn State, this PolyClay-specific mandrel makes it very easy for me to sand, finish, and polish my barrels on my drill. You can make one yourself (I give suggestions in my article on the minimum equipment necessary for penmaking), but I didn’t know that at the time.

I haven’t regretted the purchase though: the slightly flattened end nuts, long threaded rod, and knurled connecting nuts make it a breeze to use on my drill and I reach for it every time rather than my home made setups.

At $15 it’s not the cheapest thing out there, but for me it’s been worthwhile.

Round Cane Slicing Jig

I do not use this personally, because I don’t make pens like this, but many do, so I’m mentioning it as an option. If you’ve used it, I’d love to hear from you in the comments on this post!

Penn State also produces a PolyClay Cane Slicing Jig to make it easier to hand-slice round canes without distortion. If you already have one of the fancier slicers you may not be interested, or if you don’t do round canes often (like me), but at $10 it might be a useful purchase for the right person.

Thomas Scientific Blades

Switching to these Thomas Scientific Tissue Blades made a big difference for me in cutting my canes. They are thin but not overly flexible, and my slices have gotten much more even and thin.

LindasArtSpot sells them in 5, 10, and 25 packs. You may also be able to find them other places, but this is the source I know and where I got mine. They aren’t cheap — these are not the generic “tissue blades” you will find searching, they’re a specific brand I’ve found is significantly better than others I’ve tried — but I now use nothing else to slice my canes for my pens.

Wool buffing wheel

If you aren’t using a plastic polish and/or CA glue, this is a significantly better buffing wheel than any other one I have used: Buffing Shank with Wool Polishing Head 1”

It doesn’t leave nearly as many micro scratches behind, and as long as you buff thoroughly, it’s the best surface I’ve been able to get on clay using a buffing wheel.

Novus Polish

Novus Plastic Clean and Shine works great if you’re working on a drill or lathe, and has less of a chance of damaging your CA finish with the heat from a buffing wheel. The abrasive is suspended in a liquid, which helps heat disappation.

They also offer “Novus Polish Mate”, but having tried it, even though it’s cheap, I agree with the reviewers on amazon: it’s basically paper towels. I wouldn’t recommend it unless you are having issues with paper towels.

CA Glue

I was very hesitant to start using CA glue but I’m so glad I did. I love the finish and the confidence to hand my pens over to people to use long term. One experienced polymer clay maker reported that she’s had a CA-coated pen in her backpack for almost a decade and the clay+CA surface is just as good as it was on the day she made it — the pen hardware has gotten more beaten up than the clay surface.

I wrote a lot of articles on how to use CA, since it’s an unfamiliar topic to experienced clay artists. They’re all listed on my index page for my articles on Making Polymer Clay Covered Pens.

Abranet

I confess: I am not a perfect slicer. And I slice too thick. Even with the blades above. Given that I make a lot of slimlines, this means I end up sanding…a lot.

I’ve come to love my Abranet mesh paper for sanding my pens. It’s much more durable than any other sandpaper I’ve used, and holds up well to even long sanding sessions as I get a barrel down to size.

(Note that you will find much cheaper mesh sandpapers available, but read the reviews carefully. Part of why Abranet is so popular is it sands well and lasts a long time, and other mesh sandpapers often don’t have the same qualities.)

Micro Mesh Sanding Pads

I used to use polishing papers, but about a year ago I switched to micromesh sanding pads and am very happy I did. (There’s also what appear to be very similar sanding sheets, though I haven’t used them.)

The set I bought didn’t include this dispenser, and you can probably find some that doesn’t, but I suspect the dispenser is actually really useful — one of the problems I always have is fumbling for the right color and keeping them straight, and I really like the construction of the one here.

Note that when you look at any micromesh pads you will see confused people writing negative reviews about how the pads are labeled wrong — they aren’t, they’re using a different labeling system.

Just remember that the sanding pads use a different grit system. The 1500 grit sanding pad is equivalent to a 400-600 grit sandpaper. Therefore, there’s no point in using your Abranet or sanding paper up to 800 or 1200 and then switching back to the lowest grit micromesh — you’re just undoing a bunch of work.

Pen Press

If you are using a vice today (or a rubber hammer), you may want to consider investing in a pen press. The best answer is a real pen press — and there’s one for sale on Amazon right now that is $38, which is very competitive with vice prices (and there’s one at Penn State for $50.) You may be able to find one cheaper somewhere else as well.

An alternative is the Assembly/Disassembly Pen Press from Penn State, which is the the one I have and can personally vouch for it working very well. I like having the option to dissemble a pen I’ve messed up, even if I don’t use it often.

Minimum Equipment to Make a Pen

Unlike woodworkers, we’re unlikely to have any of the basics necessary to make a pen other than the clay, so here’s several levels of “what’s the minimum list of stuff I need to make a pen?” lists for buying the pen hardware, assembling the pen, making the barrel, baking the barrel, and finishing the barrels.

I do not get any commission from any links on my site, not even from Amazon. I am just sharing things I’ve found effective and helpful.

I assume you have basic polymer clay supplies: clay, blades, rollers or pasta machines, etc. If not, here are two great guides to beginner basic supplies for the clay portion:

If you’re interested in some optional equipment that makes it easier to make quality pen, take a look at my article on quality of life equipment upgrades for pen making.

Options for the pen hardware

Cover a disposable pen

The most basic thing to do is cover a bic pen. They’re fun, easy, cheap, and a good way to decide if you like working at such a small scale. All you need is a pen that won’t melt in the oven. You can try any pen that’s cheap and easy for you to get. Bic Clic Stic, Bic Soft Feel Retractable, and Bic Round Stic are all pens I have heard will work, though it’s always worth double-checking yourself in case the manufacturer changed the formula. (And at least in the US, you can often get these locally at an office supply shop as they are a common brand.)

Be sure to remove the ink from the barrel before baking.

The way most people make them (applying clay around the existing barrel) means the pen cap will no longer fit on if you are using the Bic Round Stic.

You can manufacture a new barrel yourself out of copper sheets, but it will have many of the same challenges of being a small diameter that the slimline pen kit has.

You can also make a cap, though I was never successful in making one with enough tolerance to actually stay on, so they were more “sitting on my desk” pens than anything else.

Most of the tutorials you’ll find online for polymer clay pens are for covering this type of pen.

Use a no-press pen kit

If you like the idea of a more traditional looking pen but don’t want to mess around with pressing a pen together, you can use a no press pen kit. I found them to be not as sturdy as the regular pen kits, but that may have been my error or the specific kit I bought.

Disassemble and Reassemble a Bic Soft Feel retractable

I haven’t tried these personally, but Michelle Dorn Hoffner suggested them as an in between alternative, since you do need to use a press or vice to re-assemble, but they’re much cheaper if you mess them up than a metal pen kit.

They have the advantage over the basic bics listed above of being retractable, so you don’t need to worry about a pen cap. Here’s a link, but they’re purchaseable many places: BIC 8373971 Soft Feel Retractable Ballpoint Pen, Medium Point, Black, 12-Count

Use a regular pen kit

You can find these on amazon or from any one of many pen kit suppliers — just search Google for pen kits.

Be aware that while Slimline pens often appear like a good beginner pen, the bushings (i.e. the height of the pen hardware itself, that you want your clay to be exactly as tall as) aren’t much taller than the brass barrel itself, making them hard to use because your clay (e.g. your cane slices) needs to be much thinner.

Specifically, a slimline pen has room for about four playing cards of clay before you’re exceeding the bushings. (Not familiar with the playing card method of measuring clay height? Read about it here. 10 cards should equal approximately 2.5-3mm.)

For my Atlas, for example, where 0 is my thickest setting and 9 is the thinnest, four playing cards translates to 5 thickness being a tad too high over the bushings and 6 being a tad low. I usually pick a 5 and sand back down. You can do a similar measurement with your own pasta machine to figure out what thicknesses are appropriate for your machine (all are different, even if they’re the same brand and same model, since they are not precision machines.)

That said, if you don’t care about having your first few pen barrels flush with the hardware (I didn’t!), then slimlines are great because they are cheap and plentiful and a good way to see if this is something you enjoy doing.

Options for assembling the pen

For this you will need some way to press the parts together. At a bare minimum you need a rubber hammer to use that to gently tap the parts together — but I wouldn’t recommend it, and if you don’t already own one I definitely wouldn’t recommend buying one.

You can also use a bench vice — it will need to be one that can go as wide as your widest piece you need to press, which could be several inches. While woodworkers often already have a vice in their shop, polymer clay artists are less likely to. And once you start looking at 4-5” vices, they don’t seem to be much cheaper than $30-$40 (though you may be able to get one used somewhere.) They also have the disadvantage that it’s harder to keep the pen fully in alignment — and if you don’t, you could bend the hardware and ruin the kit or even your barrel.

The best answer is a real pen press — and there’s one for sale on Amazon right now that is $38, which is very competitive with vice prices (and there’s one at Penn State for $50.) You may be able to find one cheaper somewhere else as well.

An alternative is the Assembly/Disassembly Pen Press from Penn State, which is the the one I have and can personally vouch for it working very well.

Options for making the barrel

Do nothing special

This will result in a pen that’s probably not flush with the hardware — but that may not matter to you.

It’s how I did my first few pens and plenty of people happily make their pens that way.

Use a home-made mandrel

Any 1/4-20 threaded rod (or M6 in metric) will work, but so will a knitting needle if you have a ~6-7mm needle (sizes 2-4 UK, or 10-10.5 US). If your needle is on the smaller end of that range, you will want to use masking tape to thicken it a bit, or use rubber bands or a similar solution to hold the tube in place.

You can also buy 7mm smooth rods, which work great and are a bit easier to slide the unbaked barrels back and forth on.

I prefer having something that is 1/4” or 7mm (M6) exactly and then put my bushings on also: this makes it much easier to get my pen barrel to the right height even if I’m not using a drill to sand it down and will be doing it by hand.

Buy a mandrel (or use a threaded rod) and attach it to your drill/lathe

Penn State sells a nice PolyClay Mandrel that works great either by hand, or if you’re attaching it to your drill or lathe.

Alternatively, you can use a threaded rod, but I found a 6” one (the largest my local hardware store had) to be too short to comfortably do two pen barrels so I’m happy with my mandrel purchase and I use my threaded rods for baking instead. But a longer one would work just fine (or do only one barrel on your drill at once.)

Options for baking the barrel

If you have the mandrel from Penn State, it’s designed with flat bottoms on the two large nuts on the ends so it won’t roll, and you can bake your barrels right on that.

You can use any bead rack you have or have made.

Or, I made little ‘feet’ out of polymer clay for my smooth rods as you can see in the image to the left here. The bottom is four layers of the thickest setting on my pasta machine, and the top is a single layer to hold the rod in place.

I made eight of them so I can use them to hold or bake multiple sets at once.

I like using spare slimline bushings to protect the end of the barrels so they don’t bump up into sharp edges on the feet before baking.

Options for finishing the barrel

I have several articles on hardware options for finishing the barrels, so I won’t repeat that here:

If you are finishing by hand, any sandpaper, polishing papers, and buffing method you’re used to using is sufficient.

If you are finishing with a drill or lathe, you can use your existing sandpaper and polishing papers, or you can look into abranet or sanding tape (I use both and find them very effective with the drill doing the work.)

You can also consider using CA glue (see my Making Pens page to see all my posts on using CA glue), but it’s a bigger investment than just normal sanding and buffing.

If you have a drill or lathe, consider Novus 1 Plastic Clean and Shine for your final buffing/polishing step. If not, any buffing wheels are a good choice, though these wool buffing wheels are the absolute best I’ve ever used and I don’t use anything else at this point.

Lost your pen kit directions?

The IAP (International Association of Penturners) has a very nice database of bushings and barrels and instructions that you can view online or email and print.

They also have a cheap app version of it for iOS and Android.

Prep work for applying CA glue to polymer clay pens

Getting the right hardware

You need to apply CA with a lathe or other spin-creating tool (see my articles on cordless and lock-on drills for lathe alternatives). And since your barrels will be spinning, you will need a threaded rod and nuts to keep them held firmly and moving around with the drill.

If you don’t have something like a PolyClay Mandrel or some knurled round coupling nuts or similar threaded low-profile nuts, I’d recommend using extra bushings to separate the nuts from where you will be applying CA glue, as you want your hand to be able to move smoothly from end to end.

Choosing your CA glue and accelerator

The random glue you have in your drawer or just bought from Hobby Lobby will probably cause cracking problems for you and be frustrating. Start by choosing a CA glue that will work well with pens: CA Glue Basics

Bushings

As a polymer clay pen-maker, you need bushings for a few reasons:

  • They help you sand and finish your pen barrels to the correct height to work with the rest of the pen
  • They keep your pen barrels separated from each other, when you have two (which is very useful when applying CA glue)
  • They keep your pen barrels separate from your drill so you don’t get CA glue on more expensive components
  • They keep your pen barrels separate the nuts you’re using to tighten everything on your mandrel, so you can move your hands freely back and forth while applying the CA.

Woodturners need multiple sets of bushings, due to their stronger cutting tools, but as a poly clay artist you will likely need only one set for each type of pen kit unless you are using extra bushings for separating barrels when baking or on your mandrel.

If you are using CA glue, I think it’s useful to have an extra set or two of slimline bushings to keep space between your barrels and your drill and nuts.

Preparing your bushings

If you are using regular CA glue, then the best bushings are non-stick bushings (which I believe are made from HDPE). You can order them off Amazon or get them from wherever you are getting your pen supplies.

You will likely need only one set of four.

If you are using odorless, it’s a bit trickier, since it sticks to HDPE. In that case I use a trick I learned from Toni Street’s page on finishing pens: Rub some paste wax on the bushings first, though it took some experimenting to figure out a good technique.

For a paste wax, I’ve used both P21S 12700W Carnauba Wax and Renaissance Wax and not noticed a significant difference.

I apply the paste wax liberally to each of the bushings and the coupling nuts, including the ends, give it a chance to dry, and then buff it out.

Prepare your workspace

CA glue will stick to anything it touches, and if it’s natural fibers, it will emit heat and potentially a lung-irritating smoke.

I keep some acetone around (e.g. nail polish remover with acetone) for clean up, but mostly try to avoid having to clean up.

I use wax paper (e.g. deli sheets) sliced into small squares to apply the CA glue rather than paper towel, which can react with the CA glue and create heat/smoke/fire (though you will see lots of woodturners using paper towels, and I’ve used them too. Just be aware of the risk if you do.)

I use polyethylene to protect surfaces: whether it’s a polyethylene disposable glove that I put used wax paper on, or a polyethylene sheet on my lap to protect my jeans, it’s worth a bit of work up front.

For more tips and examples of what to buy, see my article on protecting yourself and surfaces from CA, as well as the article about the risk of chemical burns when CA comes into contact with natural materials like cotton and wool (jeans, t-shirts, paper towels, etc.)
