Robocop1051 Posted November 20, 2010 Report Share Posted November 20, 2010 I hate myself right now. I had my heart set on installing a MIAD grip on my JD. While tapping the hole for the take down pin screw I snapped off the carbide tap inside the hole. I'm really stuck now. The walls of the hole are too thin to drill out a larger hole. Luckily I found a tool made by WALTON TOOLS that should be able to back out the bit.... SHOULD!?!?!Like I said earlier, FML! Quote Link to comment Share on other sites More sharing options...

imschur Posted November 20, 2010 Report Share Posted November 20, 2010 yeah what he said..ouch. That aluminum can be a little tricky to tap especially threads that small. If you truly used a carbide tap it probably worked against you. They are brittle and break easier than other alloys. Additionally their are taps specifically for soft metals like aluminum.Careful trying to remove the tap. Those extractors break too. Use oil and go slow. The hardest part will be breaking it free where it broke. Then you gotta hope there's no broken chips embedded.Good luck you will prevail!!!

TacBlade Posted November 20, 2010 Report Share Posted November 20, 2010 Another solution is the way I went. The JP Tension pin. You can eliminate the problem with the spring not working with the MIAD and you will have no play between the upper and lower. I just see it as a win/win solution. It does take just a bit longer to take the upper off, but I am never in a hurry to do this, so I am good with it. But, breaking that off in the hole really sucks!!! You will figure it out somehow, it what we do when we hit a problem working on these guns!!! I hope yo get it out of there! Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted November 21, 2010 Author Report Share Posted November 21, 2010 Tac, that's my back up plan. I didn't even know they existed till your post. I wish someone would make pins like HK. I have a G36k in my patrol car, and as much as I hate that rifle I have to admit that it is a dream to take down.Now the wait game for shipping on that elusive little extraction tool.

TacBlade Posted November 22, 2010 Report Share Posted November 22, 2010 Thats Great!!! I am glad to of help if it is needed. I had one of those pins in my SR25 several years back and it worked great. Now that I got back into the .308 ARs, I had to try it again and it works Great!! I hope you get that broken piece out though!!! Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted November 25, 2010 Author Report Share Posted November 25, 2010 I got the tool in the mail today. It worked! I will do a complete write up later tonight. I guess I have one more thing to be thankful for tomorrow. Quote Link to comment Share on other sites More sharing options...

fredseviltwin Posted September 1, 2011 Report Share Posted September 1, 2011 I must admit I did that once, during completion of an 80% receiver so it was a drill bit.Drilled it out with a straight flute carbide bit. Then tapped it oversize and threaded an aluminum screw into the hole with Loctite 690 retaining compound. I cut it off dressed the surface with a fine file, Re drilled the hole, slower this time. I also thread this hole to capture this spring and detent pin.S##t happens fix it. Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted September 2, 2011 Author Report Share Posted September 2, 2011 I thought I did a write up on this...I left the receiver in the freezer over night. I even flipped a duster can upside down and got it extra cold. I then drowned the screw in WD40. The tool was simple to use. Just extend the arms, slide them down the flutes if the tap, tighten the lock and then back out the bit. It took me seconds to do. No marring and no scratches.Voila!
