Hello Forum
History proves that someone on this forum has a better approach than what I'm intending to do and I'd love to hear it.
Please refer to the image of the surgical site (attached) I'm trying to make sense here.............

0.090" mild steel outer part (dark) with a 0.25" hole
0.090" stainless steel inner part (sorta kinda shiny) with a 0.25" hole
These 0.25" holes are misaligned by approx. 0.060" (or more)
I won't weld on an unknown grade stainless, but I'm comfortable welding on the mild steel.

My vision of a fix is to weld a mild steel plug on the outer plate then drill a 0.25" hole and accurately capture the inner part's 0.25" hole.
But, how to capture the inner parts center location without f'n it up?

Many thanks

If you are just going to bolt them together, I'd take a round file and slot both holes about 0.03". Just enough to get your bolt in.

Depends on the equipment you have. I would cut a slot with an endmill. Otherwise, I would put a blob of weld on the steel part and punch a hole with and endmill. No need to make a plug for such a small hole. Use a chunk of aluminum or copper to cover the back of the hole while you're welding. Honestly, I'm having trouble imagining the situation you are trying to solve. If you could add any details...
