Best tool bit EVER for dialing in Crown Guard lever/crown fitment...

[projectologist]

All things OP modder extraordinaire w0lf suggested this tool bit when I was at the point of fitting the CG lever to the crown of my 201/A build. I wanted a nicely rounded shape, but didn't want to spend hours slowly filing away with a micro file or try hand-holding a Dremel tool.

He suggested trying a chainsaw sharpening stone. They come in 2 sizes and for what I was doing (leaving the lever installed in the CG body) the 4.8mm stone worked best.

Works great at lower rpm's than a Dremel tool if you use it as I did with a higher torque drill press at lower speed (less chance of the piece you're holding flying out from under).

It was easy holding the CG with the lever closed against the base board with thumbs and forefingers. The stone made quick work of the shaping, maybe 5 min. total. When the fit was just right, I hit the tip area with some 1200 grit and a Tiger cloth.

Open to show the desired shape after only a couple minutes of work...
