I have a shaker trim ring with some broken studs.I know you can drill through and tap and replace the stud.Anyone have any other way to fix this?
Thanks in advance

you might ask Terry McCann he used to have an older craftsman who could weld them with some type of gas welding rod then retread them, but the old timer has passed several years ago , but Terry may know the prcess or other craftsman. trust me when he was done they were perfect . hard to believe ,but that the difference between craftsman and hacks.

Thanks for the tip.

If you can find a reputable shop that has experience with zinc welding you could ask them.
The trim rings are made of zinc commonly called pot metal.
Zinc flows at a lower temperature than most alloys, so care has to be taken with not too much heat.
The late gentleman that Mike mentioned who used to restud them ( probabaly repaired close to 60 trim rings over the years )
would heat the stud area and build it up with the zinc rod till hard, then dremmel down to size and rethread.
Finished they were same height, size and material, undistinguishable from originals.
Same process can be used with most nameplates or badges that have broken studs as most are zinc based.
He repaired many of those as well.

Investigate muggyweld.
The caveat will be to find a shop that could "build-up" the stud "tower" and have the ability to shape it into a usable fitment.
