A Billet for Billethead

This is so cool. @BilletHead likes his cast iron, I figured you would love this as I do. The ball bearing test is intriguing. Shows that these old metalworking devices are still top notch.

Seems to be fairly level...

Cool video.  I've got an anvil out in the shop that's fairly old from an Iowa farm.  But it only weighs maybe 30 pounds.  Still a handy thing.

                    That is so neat @Mitch f thanks for sharing and tagging me. You are right I like this kind of thing. I actually seen a couple nice big vices last Thursday.  I have to touch things like this when I see them and wonder where have they been and what has been worked on them. Again thanks.

The machine tool was pretty cool as well. Back in 1980 I ran an old Pratt Whitney Jig Borer before there was such thing as digital readout and glass scales. The linear dimensions in X and Y were .0001” increment dial indicators with inside stick micrometers for various lengths.

One hundred thousandth of an inch.  That's some precise analog.

1/10,000 of an inch, very common

I am lucky to get any of my housing engineers to come within a foot of the tolerance.

Had one call the other day asking me to tell him how to level the header of the opening.  My response, "to the gravity of the earth".  Seems like he should have called me with that question before he poured the concrete that was off 2" in 14'.

I guess he wanted some water drain angle! 😂😂 that’s enough for a flood!
