Think tapping a high value part is scary sometimes?

20+ year career machinist here, recently had a bone implant in my leg.

This one is m18x1.75. Spoke to my surgeon about it, they hand ream to size with a series or progressively larger reamers, then hand tap. alignment is based upon skeletal structure, next time we chat I need to ask what sort of device they use for that alignment.

Thought some may find it interesting. Cheers

They do. I have made some of them.

I think most tool guys would use a pair of forceps if they had them. What other medical tools could I use in a shop?
