A jig for accurately setting jointer knives

This jig allows me to adjust and set my jointer knives very precisely. Other than one of the dial indicators it was constructed from materials I had on hand. The plans were taken from ShopSmith’s Sawdust Sessions web site (unfortunately the video is no longer available). While this jig was originally intended for use with the ShopSmith jointer I would think that it will also help in setting up jointer knives for most any jointer.

I really like the concept. Do you have another link to the video; doesn’t seem to be working.

Doug—Thanks for posting this.

The video is not available on the SS website, but I assume you set the gauges to zero on the outfeed table, then rotate the knife to 12 o-clock and adjust so both gauges are at zero?

This jig is definitely needed in my shop.
How do you use it? I tend to think in the same lines as TheDane.

Thanks for the project. I use a magnetic base and a dial indicator now, but the design you’ve found would be a big improvement. I like the increased contact area of the metal bar stock. You don’t have to hit the bottom of the round tip on the indicator. It’s easy to get off a couple of tenths.

Looks like a pretty good jig and I bet that it works very well. Good work.

I really like the idea of two dial indicators. This would speed the set-up process a bit rather than sliding back and forth with one. Thanks for posting.

I like this!

I’ve been tossing ideas around for a while trying to get this right and it never quite came together for me. I’m gonna steal this idea for the rockwell jointer I am refurbishing.

Cool idea, I think I’ll have to make something like that. A question for anyone familiar with the common 8” Rockwell/Delta jointer: There is a threaded hole on the outfeed table and plain hole on the knife holder at TDC for each knife when it’s in the 12 O’clock position. I believe there is some sort of tool/accessory that holds the knife holder in position preventing rotation. Has any seen these?

Great jig. Great ingenuity !!

For any looking on … I’ve also seen numerous mentions of this simple method (quoted, in this case, from DustDawg, on this thread )

[BEGIN]
I have an 8” Delta X DJ20 which required all of the blades to be changed after running a board through with a hidden nail. A fellow woodworker posted this method on Sawmill Creek and it works flawless for me:

“I took a piece of 1/4 plate glass 5 1/4” x 12”
and super glued 4 rare earth magnets to it.
2 to hold the glass to the out feed table 2 to snatch the knives”.

The magnets hold the knives to the glass which is on the same plane as the out feed table.

Purchased the knives from Global Tooling and also saved a good bit of money:

Simple and Cheap

Good Luck,
[END]

I appreciate all the compliments. The only thing that I can take any credit for is posting it on LJs. It’s an encouragment to me to know that others are benefiting from it.
