thehun 20 Posted March 27, 2012 Report Share Posted March 27, 2012 I thought this would be the hardest thing (tapping and drilling trunnion) It took literally 5 minutes start to finish....stupid fast. Everything fit perfect. Tapping was easy. Just want to post this to maybe boost someone's confidence who is on the fence on doing this. By far the best mod..clicking in a true AK mag=PRICELESS 3 Quote Link to post Share on other sites
mogunner 240 Posted March 27, 2012 Report Share Posted March 27, 2012 Yep, I was so worried about snapping the tap off that I probably backed the thing out like 20 times to blow the chips out! Went smooth on mine too. Still about the hardest part of the conversion I think! 1 Quote Link to post Share on other sites
JBubbs 17 Posted March 27, 2012 Report Share Posted March 27, 2012 It was probably the part that made me the most nervous, but the actual hardest part was removing the factory trigger plate Quote Link to post Share on other sites
mogunner 240 Posted March 27, 2012 Report Share Posted March 27, 2012 I have a drill press set up with a milling vise, so even that part was easy! Quote Link to post Share on other sites
semper299 284 Posted March 27, 2012 Report Share Posted March 27, 2012 It was probably the part that made me the most nervous, but the actual hardest part was removing the factory trigger plate This +1. The middle rivet was the one I had the hardest time with. The other two were pretty easy. MIddle one took forever, and I had to use a drill bit one size larger to finish it off.

Agent Lemon 157 Posted March 27, 2012 Report Share Posted March 27, 2012 I was not very sure about doing the bullet guide on my first conversion, either. I wanted to wait until I get a drill press to do it just right, but then I ended up just free handing it a few minutes later Quote Link to post Share on other sites
thehun 20 Posted March 29, 2012 Author Report Share Posted March 29, 2012 I free handed it...it was stupid easy Quote Link to post Share on other sites
pjj342 632 Posted March 31, 2012 Report Share Posted March 31, 2012 I free handed it...it was stupid easy Yea, hand drill to drill and tap. Just go slow and easy theres no problem. In the last year or so ive been on this forum I cant tell you how many times ive seen a thead saying 'broke my tap' or 'bullet guide problem' or 'oh shit what do i do now'. I just laugh.

bigbob68 0 Posted March 31, 2012 Report Share Posted March 31, 2012 Did anyone use locktite after install. I didn't but I'm thinking I should. Quote Link to post Share on other sites
pjj342 632 Posted March 31, 2012 Report Share Posted March 31, 2012 Did anyone use locktite after install. I didn't but I'm thinking I should. Make sure you take it to the range, test it, and are certain that its in correctly. It seems foolproof, just drill the hole, and install, and for most of us it is. But once and a while it doesnt work right. So dont do anything permanent right away. Blue loctite is cool for the first range trip, probably not red. After I was sure mine was all good, I put a small dab of jbweld under the rear of the guide then used Red loctite on the screw. 1 Quote Link to post Share on other sites
bigbob68 0 Posted April 1, 2012 Report Share Posted April 1, 2012 Thanks! I already put a few hundred thru it without a problem. Guess its time for some locktite Quote Link to post Share on other sites
jbanzai 113 Posted April 1, 2012 Report Share Posted April 1, 2012 This makes me feel better. I've yet to do the BG install. I don't have a drill press, so I've just ignored the situation. I'll go for it with the hand drill. Quote Link to post Share on other sites
pjj342 632 Posted April 1, 2012 Report Share Posted April 1, 2012 (edited) This makes me feel better. I've yet to do the BG install. I don't have a drill press, so I've just ignored the situation. I'll go for it with the hand drill. The best advice I was given: 1. punch a nice divot before you drill, give that fucker a couple hard whacks, that trunion steel is hard (its made from melted nazi tanks) 2. Above all else, take your time, plan your steps and go slow. 1/4 turn or less at a time when you tap the hole. I cant even say the hole I drilled on mine is exactly straight, its not off by much though. The hand drill will do you just fine if you are careful.

jbanzai 113 Posted April 2, 2012 Report Share Posted April 2, 2012 I know you tap it slowly.....you drill slowly too? And of course, lots of oil. Quote Link to post Share on other sites
twoskinsoneman 72 Posted April 2, 2012 Report Share Posted April 2, 2012 Yeah a nice deep DIVOT IS A MUST..but yeah hand drill is easy yup. most important part of the operation Quote Link to post Share on other sites
pjj342 632 Posted April 2, 2012 Report Share Posted April 2, 2012 I know you tap it slowly.....you drill slowly too? And of course, lots of oil. Your only going through like 1/4 of steel, even if you go slow it doesnt take long to break through the bottom. Quote Link to post Share on other sites
jbanzai 113 Posted April 2, 2012 Report Share Posted April 2, 2012 I've read that most people do break through the bottom. Shouldn't that be ok as long as you don't go through the receiver? Quote Link to post Share on other sites
Shankspony 40 Posted April 2, 2012 Report Share Posted April 2, 2012 I've read that most people do break through the bottom. Shouldn't that be ok as long as you don't go through the receiver? Yes, if you go through the receiver, you're not paying attention at all. I don't think the bolt/screw supplied with my kit would have seated properly if I didn't drill completely through through trunion and the tap I used certainly wouldn't have done a proper job. I didn't have a deep enough pilot divot and went off center slightly. Post assembly, my carrier was hanging up on the screw head because it wasn't seating in the recessed portion of the BG. I managed to plane the BG a little with my Dremel and seat the screw head to the expected level. So if you do slip up like I did, it's recoverable; just take your time and think it through.

thehun 20 Posted April 3, 2012 Author Report Share Posted April 3, 2012 You feel it when its about to go through...than you just go super slow Quote Link to post Share on other sites
G O B 3,516 Posted April 3, 2012 Report Share Posted April 3, 2012 Drill slow in hard steel. The bit gets dull if the heat does not have time to disparate. Quote Link to post Share on other sites
jbanzai 113 Posted April 3, 2012 Report Share Posted April 3, 2012 How deep a divot are we talking? I've never centerpunched anything before....just freehand. Not exactly something I want to do on my precious rifle. I got the spring loaded centerpunch with the kit from Dinzag. Would one 'punch' do it? Do I need to hammer it? Quote Link to post Share on other sites
G O B 3,516 Posted April 4, 2012 Report Share Posted April 4, 2012 Use the spring punch to make an accurate center. Use a center punch and an 8 or 12 oz hammer to punch that out so the divot is wider than the dead center of the drill bit. (If you look at the tip of the bit, you will see that there is a flat part in the middle that does not drill - this is 'dead' center. If this is wider than your punch divot the bit will walk.)

RobRez 1,895 Posted April 4, 2012 Report Share Posted April 4, 2012 Glad to hear the bullet guide was easy, but I want to hear about the "Piece of cake" you spoke of!! Do you have any pics of the Cake? I really like cake. Quote Link to post Share on other sites
pjj342 632 Posted April 4, 2012 Report Share Posted April 4, 2012 How deep a divot are we talking? I've never centerpunched anything before....just freehand. Not exactly something I want to do on my precious rifle. I got the spring loaded centerpunch with the kit from Dinzag. Would one 'punch' do it? Do I need to hammer it? I would say, if you look at the ball on the tip of a bic pen, you want just a hair more than that about 1/32" deep. Its only enough to make sure your drill bit doesnt walk. I know you dont want to beat on your gun, but you kinda have too. Put a tee shirt or thin towel on a piece of wood, make sure your reciever is sitting nice and flat on it, and give the fucker a whack. Hit is as hard as you would pounding a nail. You dont need big old Thor haymakers, just hit it solid. Quote Link to post Share on other sites
twoskinsoneman 72 Posted April 4, 2012 Report Share Posted April 4, 2012 just buy one of these. Then put it in the center of the hole and pound one good hard smack with your hammer. Then your drill bit will burrow straight down into it and not walk. Quote Link to post Share on other sites
G O B 3,516 Posted April 5, 2012 Report Share Posted April 5, 2012 I use RamSet shoot in nails for punches. Cheaper and come in packs. The ones with 3/8 studs are just right for center punches. Quote Link to post Share on other sites
Roger Roger 2 Posted April 6, 2012 Report Share Posted April 6, 2012 This was the only part of the conversion that I was sweating, ironically it was probably the easiest when all was said and done. I completetly converted my rifle and waited to do the Bullet Guide until I went to the range and put a hundred or so trouble free rounds down range in that configuration to make sure I didn't have any hiccups. Once I knew my rifle worked, I then did the BG. It was extemely easy, but I was still sweating bullets though until I got to the range and put another 200 trouble free rounds down range to make sure the BG worked and I didn't F' any thing up. Like others have said, go slow with the drill (I used a hand drill), then go slower with the tap and keep backing it out and use lots of oil. Quote Link to post Share on other sites
