Ryobi 32 comversion (weedie)
Kevin, how did you mill down the piston ring pin (partially, of course) to fit the Bowman ring over it? I used a Dremel tool free-handed but it was very dicey. I'd recently bought a Dremel tool drill press stand, so I might be able to rig it up some way to act as a poor man's milling machine.
BTW, you're absolutely right about Frank's work being of first class quality. Well worth the money.
