Hi all,
Looking for advice on my next challenge!
One manifold stud had a poor thread, so we removed it (it came out pretty easily using a stud extractor).
One other has been replaced in the past with a stainless one.
So it seemed sensible to replace the others.
Mistake.
The next one I tried sheared off. Drat. That was a mistake.
I now have to extract the remains: pic of remains
The approaches would appear to be:
I've used approach 1 successfully with the lower water branch studs, so this would be my ideal approach.
I wondered what methods & success people have had with this - I realise that ideally we'd have a jig, or use the manifold and a turned insert.
Unfortunately I don't have a lathe.
I managed the water branch with a drill bit in a drill press and no guide, but it did not go perfectly centrally, and it was a bit heart in mouth. It also helped that there was a hole right the way through.
Thanks!
James

The approaches would appear to be:
- extract the remains and use a bottoming tap to restore the thread at 1/4 BSF
- drill out larger and use a helicoil
- drill out larger and use a stepped stud
