I'll need it this summer to make hand-hole and radiator cover gaskets for my McCormick Deering 10-20 tractor, lots of oiler gaskets (I have tons of oilers), a couple of carburetor bowl gaskets, and who knows what else?
I needed to make hand-hole gaskets too and I could not find one of these cheap/used so went with this style from Alpax for $40 on ebay (used)
You can add extensions to go bigger and bigger
