Talked yourself right out of it didn't you?
Magnet wont work, do the math. different glues have different strengths. it's all about choosing the right one. Jb weld?, epoxy? I guarantee 2 part urethane will work.
Sleeve it.
I'll bet your dentist could get those pins out.
Your a machinist? What size are the pins and how deep are they?
Seems like a really easy problem to solve for a machinist, treat it like broken screw.
Just make sure you formulate your repair plan before you choose a method.
Good luck.
If having experience in a similar situation, and it differs from your suggestion, qualifies as "talking myself out of it" then yes I have.
My degree is in Machine tool technology not electrical engineering, math or physics. I have been in the trade 20 years.
I am always ready to learn new things, so why don't you post the formula (math) which you are talking about so I can learn from you.
You are correct, different adhesives have different qualities.
To sleeve the pin I would have to hollow core drill around it to get a sleeve on it. If I did that why not just grab it and pull it out?
I always try to do as little harm to the piece I am working on, kinda like a doctor " do no harm". A dentist doing an extraction does not care about "minor collateral damage" because tissue heals. Wood does not heal.
Hard to measure the diameter of a pin which is sub flush. Estimating its diameter, using a gage pin on the surface hole, shows it to be about .100". The hole in the stock is about .030" deep. I do not know how long the pins are.
If it were a broken screw, I would either drill into it and use an easy out, or mill the minor diameter out then collapse the threads into the hole. Option # 1 is not practical due to the fact the diameter is so small, and I have never seen an easy out with a diameter that small, and what would be left of the pin would have no structural integrity. Option # 2 assumes the pin is straight and that you have a cutter that diameter and long enough to mill it completely out. Cutters this small generally have a shank diameter of .125" and a total length of about 1 inch. Ordering a custom cutter would be very expensive.
I always try to plan any operation before acting. That is why I created this thread, to see if anyone had faced this problem before, and what they did about it. So far only 1 post is from someone who has faced this problem and I have thanked them for their post.
Thank you, I appreciate the time it took you to post. Feamir
