A while back I purchased a Jet JWP-15CS 15" planer with straight blades that were in good shape. They are no longer in good shape, but instead are in need of being changed. I have the manual and it calls for the use of a knife setting jig, which I do not have. On my G0490 jointer, I do not use the blade setting jig that came with the machine, but instead an aftermarket jig that aligns the knives with the outfeed table. I vaguely know what the knife setting jig should look like. Questions to the team.

Is there another brand and model that uses a jig with the same settings as the JWP-15CS that is available for purchase (*ahem* Grizzly *ahem*)?

Is there an alternate knife setting jig you prefer and suggest, and why?

How will I be able to tell if the blades are set correctly?
