I'm at my wits end with my jointer right now. I've owned this older Grizzly 1018 8" for a few years, using it off and on. I built a roubo workbench with it 2 years ago and it did very well. The past few months I've barely done any woodworking because it has caused so much frustration. I don't know if it's because of the spiral cutterhead I installed in January, maybe?
The issue: The cut is tapering off at the end of the board. It's very obvious listening to it; you can hear the cut being less deep at the end of the board. You can clearly see the board lifting off the infeed table as you get to back half of the board.
Last week I calibrated the outfeed table parallel to the infeed table as best I could with my veritas 50" straight edge. I used my dial indicator as best I could to shim the cutterhead blocks to be parallel to the infeed table (I found this a bit difficult with grizzly's spiral cutterhead because you have to keep guessing TDC for each cutter). I set the cutters as best I could to ~0.003" above the outfeed table.
If this machine was flammable I would have already set it on fire.
Please help. Advice? Anyone in WNC want to lend a hand?
