If you've come across a typewriter and the paper won't' feed properly, most likely the feed rollers are worn out or have flat spots.
When I started looking on how to fix this problem I found a few websites that suggested using heat shrink tubing (which would require multiple layers) or sending them out to J.J Short Associates (http://www.jjshort.com/typewriter-platen-repair.php) which I believe, is the only company who is left that will restore platens and rollers.
Being the impatient person I am, sending them out wasn't on the top of my list and while using shrink wrap would be an option, I felt there must be a better way. This got me to thinking about using a polymer clay. I have quite a bit of experience making millefiore beads with a product called Fimo and I thought I would give it a try. It is easy to work with and is quite durable. I have restored quite a few feed rollers with no problems or complaints as of yet. I have not attempted to restore a platen. Stay tuned, it's on my "to do" list. Anyway here you go….
I prefer the Classic Fimo product as it seems to provide a more durable end result. You will have to spend some time softening it, but is worth it in the end.
To soften, break off a chunk and warm it in your hands, knead it, stick it your bra, your pants, whatever you need to do to make it pliable. This may take some time, so be patient. Just don't put it in the microwave, you will have a crumbly mess.
Obviously you have removed the platen and taken the feed rollers out of your typewriter. Use a caliper to measure the diameter of the original feed rollers. This is very important! Don't miss this step.
Now remove the old rubber from the rollers. This should come off easily with an X-Acto blade or a knife.
A light sanding and cleaning of the rods will provide a fresh start for the new material.
Now it is time for the Fimo covering. Since it is now pliable (by whatever means you've chosen), you can now roll out the clay (like pie dough) to the desired thickness. This can be done by rolling it out with a rolling pin or a jar. Just be sure the thickness is consistent and fairly smooth. If you have a pasta machine, they work fabulous. Just be sure to clean it well before making your next batch of fettuccine.
Now you are ready to lay out the rollers and cut the Fimo to size. Once you have the proper size and thickness wrap it up like an enchilada. All the food references…I must be hungry.
Almost done! Now trim the ends and smooth out the seam. Double check the diameter with your caliper to make sure the thickness is correct. Now it is time to bake.
Make sure you suspend the rollers while baking (do not place directly on baking sheet as this will cause a flat spot). I have used rolled up aluminum foil in the past however, as you can see in the photo, I recently made permanent suspenders out of leftover clay.
Fimo's baking directions: Let it harden in the oven for a maximum of 30 minutes at a temperature of 230°F.
I tend to bake only about 18-20 minutes or so, as the metal rods heat up and "cook" the clay from the inside.
So there you go. You are all set. Let them cool (lightly sand with a super fine grit sandpaper if needed) and put them back in your machine.
Would love to hear any suggestions or comments! Happy typing!
