This is a jig I made to adjust the knives on my jointer. It is oak and brass. I finished it with Minwax “wipe on” polyurethane.

More pictures and details are on my blog…

Very nice. I usually use a magnetic base to hold the indicator but I like this better. I could see making one of these.

I’m curious Stephen, what’s the point of adjusting the knives if you can adjust the outfeed table? I just went through this recently with my jointer. I came to the (possibly incorrect) conclusion that all I needed to do was level them with a magetic jig that I made and then adjust the outfeed from there.

Am I missing something?

My outfeed table is not adjustable. To cut properly, the knife must be the same height across the width of the cutter head. Each knife should be set at the same height as the others. Several sources (including my jointer manual) say the knives should be set slightly higher than the outfeed table.

Oh. I didn’t realize not all outfeeds are adjustable. That makes sense now. Yeah, I set mine to be level with the outfeed and then lowered the outfeed a bit. I made the three magnet jig which holds the cutters parallel to the outfeed and then tightened them. Much simpler than I expected.
