I’ve bought cork from these people who supply cork for automotive use.

Make sure you specify exactly what you want or they will supply coarse cork. They also list synthetic materials like neoprene which might be better?

Thank you for the information, I have purchased some cork from a local shop and will see how it goes.

Adam , rather than using a hole punch which tends to push the material outwards and split especially composite cork , I use gasket drills and you can make your own out of any round tubing filed inside to an outside cutting edge , or if you have a lathe even better made of steel , they are best used in a pillar drill with some plastic material underneath . The kit I bought is no longer available unfortunately
