What kind of trouble?
When i tried grounding a lam with this jig, the lam came out quite far from what i expected. I was aiming at 2,2mm thickness on the handle side of the lam, 1mm in the middle, and 2mm at the tip end.
What I got was:
Handle end: 1,6mm
Middle : 1mm
Tip end : 1,4mm
(Sorry for the mesurment in mm, not used to inches yet for thickness)
I bilt my jig with 2 pieces of plywood. I glued in between thickness gauge with the desired thickness every 4 inch.
I don’t know what went wrong
