Slide radius for comp fit

[RippinSVT]

I'm building a 2011 open gun and would like to machine the comp to match the slide exactly I figured I'd use a corner-rounding endmill. Anybody have a clue which size to use for this task or have a better way? I'm not keen on draw a file to blend the two with that much surface area.

Top of the slide is 1/2" R. Use a 1/2" shank carbide router bit for woodworking in the milling machine. It will make short work of it, or just turn it to 1" diam. in the lathe.

Thanks Warren! I thought about the lathe but I don't know if I trust myself yet, baby steps on that machine.

If you ever get out this way, I'll show you anything you want to know. Call ahead so we can plan a time. Write down any questions as you go along so you don't forget them.

Thank you! Side note: can you bring an extra set screw for your prone pads to the match this weekend? I misplaced one of mine when I was switching things around and couldn't seem to find the right thread at the hardware store. I'll throw you a few bucks for your trouble of course.

 Sure. Not a problem. No charge for just one setscrew.
