View Full Version : AK flat bending Question

03-21-2012, 9:22 PM
First off i would like to say hello and great site:notworthy: been hanging out in the shadows for a little bit now. Now I have been wanting to build an AK for some time so figured may as well go for it. So bent my flat and it looks like the trigger pin hole may have distored a lil bit and im hoping its ok what do you guys think?:confused:

Thanks in advance

Should be able to run the 7mm reamer through it but make sure someone who really knows (AK Team) backs me up so you don't do something wrong.

welcome to calguns!

The distortion is expected in the lower axis pin holes. That's why AK-builder makes them undersized so you can ream to 7mm and get a perfect round hole.

Sweet so Ill be good to go, Thanks again.
Wasnt so worried about the flat but more about making sure the bending jig is dialed in :43:

That looks about typical to me, it'll be fine!

Thanks again for the guidance!:notworthy:
Hopfuly Ill be able to make it out to a build party to learn any lil tips and tricks
Ill be making my own rivet jigs,I have lathe and mills I can use at my work(machine shop) so shouldnt be to hard.
I havnt realy looked into what size ball end mills it takes to get good rivets though, anyone have any insite on that? Im sure once I make one Ill will be making more :p

Looks like a Tapco flat.... Normal.

If you are using AK Builder rivets, 1/4" Ball End Mill will be just about right.

its a ak-builder flat just the standerd no trunnion holes
1/4 ball for finishing the head?
what about forming the head?

5/16" ball endmill for making divots in bucking bars and rivet sets.
