NYC.DenseCity 0 Posted March 4, 2008 Report Share Posted March 4, 2008 so last night i tried to do the BG installation.... i drilled the hole, then tried to use the tap but turned/bent it too hard and snapped the tip off in the hole. I cant get it out for the life of me. I couldnt even drill it out. has this ever happened to anyone? or does anyone have some idea how i can get it out? im worried about makeing the hole too big, i want the screw to stay in there when i get it out.

NYC.DenseCity 0 Posted March 4, 2008 Author Report Share Posted March 4, 2008 does anyone know what tap i need to buy that matches the one in dinzags kit? Quote Link to post Share on other sites
oldandslow 3 Posted March 4, 2008 Report Share Posted March 4, 2008 I have no clue, but I'm guessing that Dinzag sent a screw with the kit. Go to your local Ace hardware store, they have a metric screw gauge. The helpful old guy that works there will help you retrieve the proper tap. does anyone know what tap i need to buy that matches the one in dinzags kit? Quote Link to post Share on other sites
glennco 0 Posted March 4, 2008 Report Share Posted March 4, 2008 I Just looked on Dinzags web site- He uses 6-32 on the 7.62 and 8-32 on the .223. These taps are very common. Use a little oil and take your time. Quote Link to post Share on other sites

I took a center punch and shattered the remnants of the tap out of the hole. I pulled the handguard off and stuck my dished backing plate that came with my bolt cutter rivet tools up under the hole in the trunnion from the front, then stuck a small piece of bar stock into the receiver and then stuck a wedge in so it pivoted off the bottom piece of stock and held the backing plate in place. I then went to town with the hammer on the topside (as you can see). It ain't purty, but it works just fine. Quote Link to post Share on other sites
TackDriver 1 Posted March 5, 2008 Report Share Posted March 5, 2008 Shatter the tap that's in there, get a 8-32 screw and tap, and drill accordingly. Use fluid and good luck the second time around. 8-32's are a little harder to break. Remember, worst case senario, you drill through, forget tapping it and put a nut under the trunnion.

22_Shooter 1,560 Posted March 6, 2008 Report Share Posted March 6, 2008 I decided to just go ahead and drill the hole with a hand drill. I went real slow, making sure I kept the drill straight. I didn't have a tap handle, so I just decided to put the tap in the drill, and go even slower with that, and I kept backing it out to get the shavings out. Everything came out perfect, so all that's left to do is test fire it, and Loctite it. Quote Link to post Share on other sites

Just get the tap lined up with the drilled hole. NYC.DenseCity, what caliber is it? The 223 guides can be reworked for 10-32 hardware if you need to go larger. The x39 guides have very little bolt to guide clearance to use a larger fastener, but possibly an 8-32 button head cap screw will work.

Mine doesn't have a slip clutch, as far as I know . I swear this drill is from the 60's, with puke green plastic and all . But after doing it, I got the "I shoulda done it sooner" feeling, much like the conversion itself. NYC.DenseCity, what caliber is it?

TackDriver 1 Posted March 7, 2008 Report Share Posted March 7, 2008 Couple things: 1. There is a new standard in here. We must all try to compete with Mr. 22 Shooter. Using a hand drill to drill the hole in the trunnion WAS a sure sign of masculinity and big balls. The bar has been raised. He used his drill to run the tap in and out! I am impressed, sir, and must say you have a brass set! 2. NYC ; I can confirm that an 8-32 button head socket (allen) screw will clear the bolt IF you (just barely) file the top of the screw so that it's flat. Quote Link to post Share on other sites

Cobra 76 two 2,677 Posted March 8, 2008 Report Share Posted March 8, 2008 I have often used a hand drill for the same thing. Drilling a hole for a screw in the trunnion is nothing. It would take longer to set it up in the drill press than it would be worth, when all you have to do is center punch it and drill it out on the workbench (or pool table like I did my first one...) Using a hand drill to tap a hole is very common and it happens to be the way I always do it with smaller taps. You can keep the center axis consistant and not have to let go of a tap handle every turn and try to keep it straight. It does help a lot to have a variable speed drill and even more if it has a clutch. If people are going to make wise ass sarcastic remarks they should use the smilies. That's what they are for. It helps us figure out who needs their dicks stepped on to try and keep them in line. If making honest positive statements, then it's not necessary to go overboard with bold print and capitalization. It only confuses the issue and makes people think you are being a wise ass. Quote Link to post Share on other sites
MD_Willington 11 Posted March 8, 2008 Report Share Posted March 8, 2008 I have the rifle at a friends place and he has a huge shop and a lot of tools so I'd probably use his drill press... but just for future reference what would you set the clutch to...? My drill has settings from 1 through maybe 14 & DRILL Quote Link to post Share on other sites

Just so it's known, I wasn't bragging or anything. I was simply stating that I had given up on the idea of buying a little press just for this job, that would probably not get used for anything else, and went ahead with the hand drill.

Then I put it back down, and said to myself "You've already bought enough tools for conversions, that will get no use elsewhere." My main concern was the using the tap in the drill, after reading quite a few stories of people snapping them off in the hole.

TackDriver 1 Posted March 9, 2008 Report Share Posted March 9, 2008 22 shooter. It was a compliment and a joke. I'm sorry that no one picked up on it. Guess it got lost somwhere in the keyboard. I will try to use smilies next time. I really never thought someone would get offened by me saying that they had enough testicular fortitude to chuck a tap in the hand drill and go at it. Who knew.

I wasn't offended, I was just surprised at the out-of-nowhere-wisecrack. CockDriver was kind of fucked up though. True, true. I was just returning the sarcasm. Maybe a lil overboard.

wlchase 0 Posted March 12, 2008 Report Share Posted March 12, 2008 Wow! Talk about timely! Larry Potterfield of MidwayUSA just had an "American Rifleman Tip" on tapping just the other day! Like Larry said, "1/4 turn in, back it out, 1/4 turn further, back it out. And use plenty of oil!" Bill Quote Link to post Share on other sites
dinzag 31 Posted March 13, 2008 Report Share Posted March 13, 2008 Yes, you need to break the chips. Back off frequently. If you've never tapped a hole before, practice on something else first. DON'T just crank them in there! Quote Link to post Share on other sites
