Hello to all,
I have a Jet 6″ jointer that is giving me trouble. When I try to plane an edge that is parallel to clean up the saw kerf and/or reduce width, on longer boards I end up with it cutting O.K. at first but leaving some uncut wood at the trailing end. Suspecting that something is out of alignment (tables) I got out the owners manual and tried to see what was covered under troubleshooting. Very little. I laid a straight edge on the outfeed table and raised the infeed table to look for any gap, and found the end nearest the knives was lower than the opposite end. I’m not sure if this can be changed since I only see gib adjustment. I’m wondering if anyone else has had a similar problem?
Thanks
Greg

Gill,
There are several things to do about the alignment. First, you should make sure that there is no dirt or debris on the infeed or outfeed table ways. Debris can cause such misalignment. And it can be either table. You must remove the tables and clean and re-lubricate the ways.
Then make sure the gibs are snugged up but without impeding the movement of either table. If the misalignment is still there, you will need to shim the low end or corner. You can buy shim material, but you can also try cutting material from various kinds of metal cans first.

Gill,
The usual cause for a jointer cut to run out is that the outfeed table is slightly higher than the cutters. This sometimes happens as the cutters get dull. But first, be sure the stock you are jointing isn't bowed, and lifting away from the infeed table as you are feeding it thru.
Good luck,
Ray

Gill,
Check out the "jointer" section in John White's book, "Care and Repair of Shop Machines"! He covers jointers end to end with nothing left out in the middle! It is an excellent reference for the common shop tools. For $20, it's a resource I wouldn't be without! It's available at most woodworking stores and libraries. No, I don't get a commission! LOL
