Planer Knife setting guage

Rockler has a magnetic bar jig that will hold the blade at the same plane as the bed. Another trick I’ve read about which works the same was some sort of flat aluminum stock extending over the opening in the tables with a couple rare earth magnets on top hold the knife right against it (outfeed table height) while you tighten them down. So one across each end of the knife.

These should work are sized most benchtop planers. I used a pair for years on a Delta 22-540 because the factory jig was such a piece of crap.
