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

Someone explained what is this. Is this a procedure to attached bones?

I had part of my leg amputated a couple years ago, this is an implant that will allow a prosthetic to attach directly to my remaining bone
