I think I've tried almost every cutter available thru the usual aviation outlets. They are all expensive and some worked marginally well but most just made a mess and left lots of paint chips, metal slivers and junk on the outside (hopefully) of the filter. Eventually, every one of them got violently thrown against my hangar wall. I decided there has the be a better way. So, I bought a Jeg's oil filter cutter that is very robust. A buddy that owns a machine shop milled out a center slot to allow both the male and the female type filters. He then welded a block to the bottom so I can secure it in my vise. The plan is to place the filter in the cutter (mounted in the vise) and then turn the filter using a 1" wrench while slowly increasing the cutter pressure. Tomorrow, it gets a coat of flat black paint and a trial run. Report to follow.
