Not Ranked
I bought a new set of number and letter punches. The requirement is for the characters to be at least 7mm tall. The punches I had were only 5mm so I bought some that are 8mm. I tried stamping the numbers directly into the chassis bit I couldn't make a decent impression as the steel of the rails is pretty hard.
I was in a hurry so I stamped them onto a piece of aluminium and then rivited that to the chassis but they said that was no good. I'm now working on stamping them into a strip of steel sheet and I'll weld that on to the chassis.
Cheers
