CUTTING CORK QUESTION?

I’m making turned wooden coasters for Christmas presents and having a real problem cutting sheet cork for the inside bottoms. Hobby Lobby sells 3 1/2” pre-cut cork disks but I need smaller ones like 3”. I’ve tried cutting with scissors and with a new X-Acto blades and they seem to always tear before I get a circle cut completely. You can buy smaller cork cutting punches but not in 3” size that I can find. Any ideas? HELP!

Find a plumber that works with 3 inch pipe and get a short piece from him. sharpen the edges and you have a 3 inch punch.

Agree with BigTiny. Sharpen pipe should work well.

You can use a compass and replace the pencil with an Xacto knife or a scalpel. Use the veneer cutting technique – do not cut all the way thru the first cut. 1st cut scores the wood, second cut follows the same groove, third cut finishes the cut.

Check out Blick Art Supplies.
I picked up a cutter that allows for infinite sizes and it cuts through cork with a sticky backing like “a hot knife through butter” to use an old saying!
I paid about $10 for it.
I tried all the other methods and they frayed the edges or I couldn’t get it quite round enough.

you could sandwich the cork between 2 thin pieces of wood cut them out on the band saw.

Hi John,

Some great ideas suggested above. The only other thought I have is a 3” hole saw mounted in your drill press. You might have to sandwich the cork like Jimthecarver suggests. Good luck.

I’ve done this with a sharpened pipe as BigTiny suggests; has worked well for me.

I would use a rotary cutter. They make circle jigs for them. Look in the craft or fabric stores.

Thanks Ellen I looked at Dick Blick’s X-Acto Compass Cutter for $8.40 plus shipping and it should do the trick I hope. ;-)

I also like the suggestions of using pipe that has been sharpened. I think 3” exhaust pipe would work it could be chucked into the lathe and sharpened with a file at low speed. The “sandwich idea” sounds interesting too.

Thanks everybody!!!!!!!!!!!!!!!!!

But I’m still open to more ideas.

It might be sufficient to glue the cork to strong paper or thin cardboard (or even thin veneer). this should stop the cork tearing and will be hidden under the cork when it is fixed to the coaster.
I think scissors are less likely to tear as they have a shearing action rather than a slicing one,
