    Hole punch adapter

    For a client's project (theatrical chain motor controller) I needed to make a large number of holes in a heave gauge steel panel. No problem, I have a hydraulic punch puller.

    Except, I didn't have the right size punch and die in my set. Ok, I'll just get the right one.

    Well, poo. The new die takes a metric sized bolt and my puller is inch.

    Ok, to the lathe!

    I made this adapter out of 0.750 drill rod and it worked great!

    Don't tell anyone, but I had to make two adapters, part way through the batch of holes something shifted and the die jammed, bending the first adapter into an artistic, but less than usable curve.
