Thought I'd share this cork cutting jig I made, using 1 1/4" sched 40 PVC pipe, screwed down to a piece of wood. I glue the (burnt) cork together, slide it into the end of the jig, and slice rings at whatever thickness I want. When the burnt cork bar starts to get short, I just slide reg cork rings onto the dowel, to keep it feeding squarely into the jig, and keep cutting. I stop the dowel short of where I'm making my cut. I use a dowel cutting saw I picked up from Midland Tools (about $12).It's important to use a sharp, thin kerf, broad blade, as a narrow blade would try to turn w/in the miter slot. It works really well, and dirt cheap.
