Hello;
Well, in my quest to help my 57 chevy, I was working on my rear glass frame noticing that a stud that accepts a clip to put the mechanism on was loose. I tried to use a punch to tighten it but didn't do the job, so, I get this brain storm to drill through it and install a small screw or bolt and use that to tighten it up. Well, I drilled about half way through and had another brain storm to tap it (4-40) and use a fastner from the back side. Don't you know that I only had about two threads in when the tap broke, just before I backed it out!?!! Evil or Very Mad
Then, I got another brain storm to drill from the front side. I got it drilling really nice and , I guess when it went through, hit the broke off tap and broke the bit Shocked
Now, I don't have too much of a plan for saving my part other than using welding of some sort.
I know that there are some metal working genious' out there, any body got an Idea?

Thanks,
Bruce

At this point, with a broken tap, and drill bit in the stud, just how loose is it?

I know exactly what you have there.
Part of my job for many years was to go out with a portable EDM and
fix problems like yours.
The big problem with that, it is quite expensive.
You will have to weigh the cost against going after it with a welder.

THIS^^^^

Had this situation on a pistol once, broke a punch trying to get the rolled pin out. Pulled the pin rest of the way then broke another punch going the other way. Finally decided- "Well, it still shoots I just can't clean it real good!"

If you broke it twice... maybe its fixed? Seriously, good luck and be careful.

Hello;
I tried to find another "stud" to remove the bad one but havn't lucked up on it yet! I'm thinking that welding may be my only fix, at this point.
I do however have a place to go and look for a replacement. Thats Skycraft in Winter Park, Fl. It's the kind of place you have to pack a lunch, go early, take lots of cash. All sorts of "wonderful things there!!!
