Cut the new thicker ACE blank lastnight for the trunions. I'm glad I didn't use the original thin ACE blank I used as a practise peice.

One thing that has worked out really well is having an identical kit to use for parts fitting. I have my first barrel out of the trunion and I have been using my other kit that is still barreled to fit up stuff. I made sure both kits had the same measurements before I did this and they are both AMD's also.

One thing I also learned is to not trust the template because it's hard to get it straight on a new blank. This time I'm going to take measuremnets off of my ORF AK for pin loctaions. All I have to remember is measure again and and again to make sure I'm okay.

I had a rough time getting my template lined up too. I ended up drilling my holes a little smaller than what I wanted and then filed them out a little to make sure everything fit right. No problems yet.

That's what i did too. Next time, I think I'll measure and find the middle of the bottom and then line it up with the middle of the template. This might make it a little easier. Another thing that will certainly speed up my first build, is finding something that will center punch my holes a little better.

Have any of you guys had problems with the bolt carrier binding too much as it slides over the hammer? My AMD is built with the old Ace blank, and I'm currently using a new Ace blank for my PMKMS build. I don't want to assume it's just the upper rail and take off too much metal. They both have Tapco G2 trigger groups. The lower rails don't seem to be causing too much of a problem. I'm thinking I might just need to smooth the upper rails and round off the edges.

I haven't seen an ak yet that doesn't rub on the hammer, even the store bought ones, but roberus has a video out on how to make a homemade receiver and he removes a little metal from the hammer at the contact point to solve this problem. As long as you do it slowly as to not overheat it and loose it's temper, he says it will be fine. I had to do this with my first homemade receiver build and have not encountered any problems with it since. I have run several thousand rounds through it with no problem. ak'sr4me.

This is probably why factory receivers have that dimple so the trigger axis pin sits lower huh? I've heard that the G2 hammer is only case-hardened and if you remove the surface metal it's soft underneath which wouldn't last after a few hundred rounds if that.

I didn't know that about the G2 triggers. I use the original trigger groups because I get my american parts count other ways. As far as the lower axis pin hole on the recievers, I am sure it helps but my sar 1 still rubs on the hammer noticably. ak'sr4me

Am not much of a trusting soul so I tend to measure things rather than rely on the template.

I generally place the hammer about a 16th of an inch below the Ace template.

Learning this required a couple of very skinny hammers.

Damn... I hope I can get by without messing up the hammer(s), but I guess thats better than re-doing the 3 recievers I've built.
