How I made my Beavertail grip safety fit

I picked up a Foster Stainless Steel Recon Blem when they were on sale and I had a Stainless Steel Beavertail grip safety with a 0.250" radius instead of the Government type notch. First, I made the tool below on my lathe. The hole in the frame where the thumb safety goes is slightly smaller than an 8-32 bolt. So, i made the shaft on the tool undersize and threaded the shaft 8-32 and tapped out the spool 8-32.

Using the kiss the cutter and back off, I made multiple cuts with the 1/4" carbide end mill.








I removed the frame from the milling machine vise and finished up with files. Now the Beavertail fits and functions.

That obviously took a lot of re jigging to rough out the tangs. If I didn’t have a rotab, I’d just stick with files...Nice work on the hand made fitting guide though. Did you finish the OD right at .250” or did you leave it a tad bit oversize?

I made it a little oversize and filed to fit.

Before I picked up a rotary table used a aluminum plate where I drilled and reamed for a .156 piece of drill rod. You had to find center of that pin in the Y but once established you could come in and rotate the frame by hand. Much like that old fixture someone use to make awhile back. Would I do it again? No. BUT it did work. You must pay attention to whether your rotation is climbing or conventional. Like be very sure you know which you're rotating.

Would you do it again if you didn't have the rotary table?

If I absolutely had to? Yes. It is paramount you understand the direction of rotation though. Baby cuts. I mean baby cuts. There will be a little chatter so ensure you're using gauge pins often.

I have a rotary table for my big mill that I could have used. But the garage is not heated like the basement. I have a rotary table for my Mini Mill, but I do not have the T nuts for the T slots yet. I saw a guy on Youtube use a grinder, but I have had to clean rust spots off stainless caused by someone grinding carbon steel near stainless, plus the frame is stainless.
Lots of ways to do it right, results are what counts.

Having tried it both ways, I think now I could probably file the tangs down by hand faster than I could get the vise clamped and indicated

Seriously, it really doesn't take very long at all if you have the right file for the job.
