Anyone here have a large hole saw? I need to have some washers of sorts made to cover up some chipped glass around some holes that were drilled in my tank for a closed loop. With out these I do not think there is a safe way to get a seal with the bulk heads.

These would be for two 3/4" bulk heads.

These would be for four 1/2" bulk heads.
