Well.....the old adage "if ya don't know, ya don't know" still holds true.
When I bought my Delta jointer at a garage sale a couple years ago for $50.00 I don't think I had ever even seen a jointer except on the sales floor at Grizzly. I know I didn't understand how useful and important a tool this is in a shop.
Ennyhow, I am glad I bought it and have it. But, I was using it a little dangerously and not getting best use from it until recently. Someone sent me (here?) a YouTube on jointer tips. From that I learned my (all?) jointer has a feature I wasn't aware of.
There is a handle (I cleaned up, painted and made a handle for mine) for adjusting the tilt of the fence. But what I didn't know was that it also could adjust the width of the cutting area. This, for safety, should be used with the narrow setting. The handle can engage two nuts, each has a different function, angle or width.
It also can save wear on the blades not dulling the same spot.
Now I know.
