Don't need one. Can put on some dyken and scribe the aluminum so I have a line to file to.

And that's how I would do it. But your sentence said you'd use files
"along with a machinists square to ' file to fit,' so I was pulling
your leg about filing to fit, using a machinist's square. d8-)

If you talk to him further, tell him how to do that layout, and to
scribe diagonals to find center for drilling the hole, and about prick
punches and center punches...

If you get that far.

I definitely said that I would use files. Along with a vise to hold the part, a well lit shop with heat, a scribe and dykem as well as a machinists square.
