I have a General 80-100L, 6" jointer and spent an hour yesterday changing the blades. I have changed the knives several times in the past with no issues.
After adjusting the outfeed table to get rid of the trailing snipe I decided to test the entire 6" cutting path by edge jointing a 3' piece of maple at various fence settings.
The front 2/3 of the cutting path (0-4" of exposed blade) worked perfectly, but the last 1/3" of the cutting path cut the first foot or so of the part fine, but the last part of the test piece had a noticeable taper all the way to the end. It is almost like halfway through the cut the outfeed table drops tilting the test piece away from the blades.
I've tried adjusting the outfeed table, but in order to get rid of the taper on the outside fence setting, I end up re-introducing the snipe on the narrower settings.
I'm believe the knives are installed ok, and I took particular care to insure that they were all set the same way with the knife setting jig. The tables don't appear damaged or out of plane.
Any suggestions on what I should be doing?
Also, has anyone who may have that same machine replaced the stock cutterhead with a helical unit? Was it easy to swap out? How does it work?
