Evening all.

My no1 daughter has snapped the lug on her plastic watch, so I’m making a new case.

No it’s not cost effective, but why have a workshop eh?.

I was given a box of metal bars, including some stainless steel. One of the bars is a good size to make the case from, so I’ve had at it. It’s non magnetic, and it doesn’t seem to work harden or be the usual pig to machine that I’ve had in the past (316)

Is there any simple way to tell what alloy it is - so when I want some more I can actually buy it.

Dave

If it machines easily it may be 303 grade. 304 can be a bitch to machine and 316 is easier but not to drill and tap. 303 wins for me every time for the cosmetic stuff.
