Now that I actually understand what I am supposed to do with a square
graver, I have to prepare the rest of my equipment.
I had an old engraver’s ball which someone very generously gave me a
few years ago, but in the process of a move I had somehow misplaced
one of the two jaws which insert into the main vise and the pins to
go in them.
Replacing the jaws are no problem whatever. I’m simply using my CNC
to machine a new pair in aluminum, and I can sweat the small stuff
there like milling holes and attaching a shaft for each bottom.
The bigger problem is what kind of pins to make. I’ve got brass road
and bits of rectangular brass. I can machine the bits of brass to
whatever shape I want, then drill a hole in the shape and fasten it
to a piece of brass rod, then hard solder. The result would be a pin
with a certain shape of head, like square, triangle, etc as I vaguely
remember the old set having. Making it that way is easier for me than
machining each pin as a single piece.
So. how many what types of shapes for pin heads should I make, to
recreate a complete set?
I want to be able to get my engraving ball operational so I can
practice using the square graver with it.
