- Gasket material. Either gray fiber or cork. Buy at any auto parts store; comes in a roll; usually 1/16" thick.
- Hole punches. Found mine at Harbor Freight.
- X-Acto knife. Walmart or any craft store.
- Fine, black pen.
- Straight edge.
In less than 15 minutes, I now have new gaskets with some cork left over for future gaskets and can proceed on my project without waiting on overpriced gaskets to arrive.
