Here's a easier way to do the pitch gauge. I've taken off the plate scanned it, reversed the image
Sprayed 3M on the paper stuck it to the backside, trimmed excess paper then fitted gauge plate
in the other direction. Warning:The pivot screw is a 5-40 tap. Did not know that when I had my first one
The other screws are 4-40. Drill & tap the 4-40s in a new spot cause you will need to countersink them.
If everything is lined up right the pointer should line up perfect as shown in the pic below. If not U can always
take it off print another one & try again. Here's the scan if lined up it should fit perfect. And don't forget to
cover the paper with clear tape afterwards.
Enjoy
