I mentioned Wal-Mart because it’s one of those places that seem to be close to anywhere that I’ve seen inner tubes sold at.
However, the plant I worked at we didn’t have to go buy them. The plant recycled inner tubes into rubber slabs that was then shipped out to various companies (3M was our largest client) to be made into products. So we had an abundance of inner tubes.
Now keep in mind we were working on much larger gaskets than what you’re dealing with, but I still thought I’d tell you how we made our gaskets. We cut out a flat piece of inner tube to go where we needed the gasket. Then with one man holding the material in place, another man, using a ball peen hammer, tapped the edges all the way around and into any bolt holes, perferating the rubber material. Then it was just a matter of taking a razor knife and finishing off any material that was still holding waste material on. Shop made gasket for something that wasn’t made anymore.
In the automotive mechanical business, that I’ve also worked in, there’s another method I’ve used to make gaskets for obsolete carburators and such. I used the backs off of spiral tablet, the thin carboard kind. I just marked the pattern for the gasket with an inkpen. Then I cut it out with a razor knife or scissors, depending on the shape of the gasket. I used cardboard on carburators because it soaked up and became resilient to gas leakge. Gas would make rubber swell and fail too quickly though.
