This is a simple device to help set the blade height on my Jet jointer. I simply found an appropriate piece of scrap lumber, and this one happens to be fir. I then bored four 1/4 inch holes just deep enough to set four neodymium magnets into the wood so that they are flush with the surface. Finally, I epoxied the magnets into the wood.

If I were to do it again, I would use 1/2 inch magnets. This device works fine, but could use a little extra holding power.

What you do is place the blade setter on your jointer’s outfeed table, with two of the magnets right above the blade you wish to set. The blade should be in the…spindle (is that what it’s called, or cutter head?) and the spindle should be rotated to roughly the highest point in its circular travel. The blade will be attracted to the magnets, and will stay there while you tighten the blade in place.

The shine on the wood is excess epoxy. You can see that I did not spend too much time making this pretty.

Really like the concept. Does it work well?

djang000, it works pretty well for me. One thing I have to figure out is how to stop the spindle from rotating while changing the blade. People say to wedge it, but I do not know where to place that wedge. Again, I would suggest 1/2 inch magnets instead of the 1/4 inch ones I am using.

Have your say...
