Tormek / Wet Grinder Scissors Jig Notes

I designed this scissors jig to work with a Tormek T-7 wet grinder, which has a 15/32" diameter support bar, but it can be modified to work with others. I made mine from PLA, setting sparse infill to 50%, which has proved adequate so far for this application.

You will need to print one jig support, one lower clamp, two upper clamps (if you intend to sharpen both right- and left-handed scissors; right-handed shown), and three knobs.
