I have a Shop Fox copy of the W&H moulder that I am very happy with. I’ve made a couple of knives on a wire edm that I have access to. They have worked well on reclaimed pine but I don’t know the proper height to cut the knives. If they are too short I don’t get the full profile and if they’re too long the feed rollers don’t have enough pressure to feed the board. There seem to be a fine line between too long and too short. Anyone know how to determine the correct height for the knives? Thanks.

Could you measure a new set? Trial and error? Hope this works out for you.

It’s a trigonometric formula. if you can’‘t manage the math
you probably shouldn’t be grinding your own knives.

The correct formula is you need 1-1/2” from the bottom of the knife to the deepest part of the profile. Or this works also depth of cut plus 1-1/2”
