an gasket cutter like this http://www.allpaxcorp.com/cgi-bin/a/products/extension.html?id=NsYhV79K is the ticket for round gaskets that have a id larger than two inches. if it needs holes in it a hole punch like this http://www.allpaxcorp.com/cgi-bin/a/products/punch.html is excellant plus you can make little gaskets that dont require holes. since i run power boilers, i have access to both of the deluxe kits. when i can't make one with one of these tools its back to the ball peen and scissors or a combination of all.
