A while ago I posted regarding my set-up issues on a G0586 8” Jointer. At the time, though, I had no gauges with which to measure anything and was just jamming in shims left right and centre. I do now, and I’ve tried again, but I’m still failing.
I’ll write down my process. Please point out any errors if you see them:
1. Brought the infeed table level with the outfeed, and I used my dial indicator to get it spot on.
At this point I considered it done, but I went back and checked everything over. It was all perfect until I retightened the gib screws at which point the outfeed table – at the cutterhead, near side (away from fence) – dropped down by 0.01”. I loosed, added two shims, retightened and it was fixed.
I know this sounds incredibly ridiculous, but at this point I have 2 shims on each side at the top of the dovetail ways, and 1 shim on each side at the bottom. Surely this would all just cancel out to 1 shim on each side at the top? Well, I don’t know how either, but the measurements said it was correct.
I now go about checking and adjust the blades. Zeroing dial indicator at the outfeed, finding the high dead centre, rotating cutterhead ‘til the indicator hits the top of the blade and setting to zero. I did this all around just fine. It was time consuming, but in the end I got them all to +/- 0.001” of the table, so +/- 0.002” to each other.
I re-tighten and re-check everything. All seems fine. Run some wood over it… I get a wedge. A big wedge. I. Do. Not. Understand.
At this point all I can point at is my straightedge. I could never dream though that even if it’s not quite as accurate as others out there, how is it creating such incredibly poor results? I refuse to believe that every woodworker who owns a Jointer also owns a $100 straightedge.
So, across two separate online stores I currently have in my baskets: Assorted brass shims, 36” Veritas Steel Straightedge, new jointer knives, jointer knife setting jig.
If any of you can shine a light on something and save me from throwing $200 at my Jointer please, please share your wisdom.
