Curtis used to sell sidefolder flats but he is out of stock apparently.

Make sure you match your trunnion to the drawing.That drawing is originally what K-var used to supply with their new Bulgarian parts not with parts guns.I'm not sure it's to scale or even if it's an exact match.It's slightly different from Russian side folder.Mostly in placement of rivet holes and maybe some size or fitting.Leave some extra metal.I received that same drawing from K-var.It's available on the internet as a PDF file but if you print it I'm not sure it prints to scale.I see that version is a jpeg.Maybe it can be converted to print.It looks like somebody acanned the drawing that came on paper from K-var.I'll see if I can find mine.

I don't know if it will print to the proper scale/size but here is the link to the printable PDF file.

This is a PDF of the same diagram that K-var sent me for the Bulgarian AK74 when I bought a new stock from K-var.The Russian is suppose to fit a bit differently or maybe all of them require a bit of fitting.

Im using the original stubs as templates for my build. I could probably scan those for you if you cant come up with something else.

I had the drawing from K-var, but when I did mine, I used the dimensions on the drawing and a protractor, calipers, and straight edge to make my own glue on templates.

I'm getting the stamping dies drawn up and ordered by the end of next week. Then I'll have the flats again.

It's just too much of a pain to mill the angles on the flats to modify them. If you guys can't wait until the ones are stamped I might have my CNC shop make a few sidefolder flats out of the Tapco flats.

Done a few of these. I never tried to use it as a template because I couldn't trust the drawing, or the accuracy/model of the trunion. I just took the measurements and used them as apocryphal data.

The first cut was the angle off the back, done short, and file/grinder finished. Once I got the trunion fixed in the rear, and sitting properly, I then measured and scribed for the holes. I got the left side done first, and went right through the trunion to the other side. Perfect.

It didn't suck that I had a previous one handy to eyeball either.
