[DeTomaso] Headlight Bucket Studs - solved

[Mike Thomas]

Thanks.  I actually solved the issue similarly to your description, but using an “elevator” bolt which has a broad flat top with a four sided shank underneath before the threads.  I ground the broken studs flush at the back, punched and drilled them out, then with a square file shaped the hole to fit the four-sided section of the elevator bolt.  JB sanded the top of the old stud to bare metal then JB welded the new bolt in place, tightening it on the backside to hold it in place while the JB set.  I used a ¼” by 1” elevator bolt.  I did this to the two that were snapped off, cleaned up the threads on all of the others and bought new Nyloc nuts for all.

 

Once again, McGyver to the rescue . . .

 

I have art work for anybody that would like to see the process and result.

Just as a thought and trying to not piss off any of the overly pedantic members...I have also experienced a similar situation...I believe that if you are very careful and center punch the broken stud after filing it flat or carefully grinding flat then center punch 

You can successfully drill out the remainder....most important is to have the piece rigidly held in place as you don't want to drill off center . You can then from the back side epoxy the new bolt in place.  I have had some success in using button head Allen bolts.

Good luck. CHARLES 5346

I have my headlight buckets off to modify for the Cat Eyes, and on one, two
of the studs are snapped off and on one of the two remaining, the threads
are rusted to near useless.  Questions:
Are the original studs welded in place?
Are studs with the broad, flat head such as those available, and what are
they called so I can do an online search?  Do the vendors have them?
If I were to drill out the old studs and put new ones in, would it be best
to have them welded in?
Or, what metal adhesives might be recommended to use to secure the studs to
the bucket without my having to find a welder to do that?

   bought new Nyloc nuts for all.
