Ordered a set of the M1's tonight, super excited. But I got to thinking, with them being 304 stainless, anybody ever try to tap holes to mount stuff (thinking fluid rez's) ? Or run anything through them ? Considering getting some of the bar filler stuff to help reduce vibration. Any thoughts ??

just cut the nubs off the rezzy's etc. You tighten them up enough they don't move , mines been like that for years

As for the Bar filler yes do it , wish I had ....just to lazy to do it now

I have a friend that builds brewery tanks, all food grade stuff and he welds a lot of 316 & 304. I'ma see if he can weld some threaded inserts for my rizoma cups. Try make it clean.
