Hi all...I have a 6" bench jointer...it's a Geetech (I was told they also make Jet and others). It is sturdy and well made. The problem I have is it cuts more off the front of the board than the back. I ran a piece of 6/4 walnut through it several times...at the front end it was near 5/4...at the rear still near 6/4. I can't figure out what's going on...maybe technique? I haven't used a joiner in quite a few years...but I never had such an issue.The beds are flat and perfectly in line...the cutter solid with no apparent slop in the bearings...the whole tool bolted solid to a workbench. At any rate it doesn't seem that bad technique would produce such a discrepancy. I just don't know what to do! Have any of you had a similar problem? I would sincerely appreciate any assistance. It's not just on one piece of lumber...I have tested it with several. Thanks!
