That could help me check hardness on a bunch of lead muffins that I need to separate? They are either linotype or ww.
Thanks

If your just wanting to check each muffin for either being Lino or WW.
I would think a automatic centerpunch should give you a
physical difference that is easily seen with the naked eye.

Would this automatic center punch be useful for sorting wheel weights? steel/zinc vs. lead?

Great idea Jon!
I ended up looking at the cast iron skillets they had and the impulse to run down there was almost to great too bear! :mrgreen:

I think it would.
you should get a large dimple with Lead alloy,
and just a tiny spot on Zinc or FE
also, back to the op,
maybe rounding the point would help make
a dimple size differentiation between Lino and WW alloy.

You can sort those with a screwdriver.
The WW will scratch easily.
The LINO will be difficult to scratch.
You will have no trouble. You will see what I mean after a few scratches.
After you do a dozen of each, you will be able to tell the difference by sight.
