"It takes 2 years to learn how to hand stitch." Yeah sure looks like a hell of a skill, whacking a chisel.

But did they do that in the period of the file machine Rob is interested in? From the looks of it I'm guessing nineteenth century. Or earlier? That's what I was curious about.
Arbalist:
This French one is C 1700 apparently.
vtsteam:
Wow, Arbalist, And it looks modern in comparison!
The first is an amzing example of blacksmith art. This one of engineering, at such an early period.
If someone turns up a sand blaster for files from the 1700s, then that would answer my question of how they heat treated and preserved sharpness. Just showing a big set of bellows isn't fair...was that actually how they did it? Or was there another way used..... :whip:
ps. I bet a lot of the above file making machine was shaped with files!
Arbalist:
Perhaps it was, I wonder when the milling machine was invented?
