Had a few minutes to look over my used machine last night, and the beds are definitely not coplanar. My 36" straight edge is showing 1/32" gap with the beds set level to one another. In other words, the infeed table slopes down as you move away from the cutterhead. Ive never actually adjusted a parallelogram bed jointer before, and i dont have a manufacturer's instructions to go off of on this one. My DJ20 was ok and not worth messing around with for the 8 months i had it. After that, the 12" grizzly was surprisingly dead on the whole time i had it. Truth be told, the only time ive adjusted a jointer's beds were for a friend with his 8" dovetail ways.
Unfortunately, youtube only has grizzly and the woodwhisperer to go off of, so hopefully someone here can give me some real insight on how to do this task. Looking at the machine, there are 8 holes in the beds that correspond with the nuts that adjust the cams. I assume these holes hold set screws or bolts that keep the cams in place after adjustment. They are filled with years of crud right now, so i cant confirm whats in there. Next, ive seen two ways of doing this. Setting the outfeed table parallel to the cutterhead body, then adjusting the infeed table to be parallel to the outfeed table. OR, ive seen people suggest to raise both beds to their max height and then set them parallel to one another that way. I imagine all roads lead to rome in this instance, but which is the preferred/easiest method? The cam adjustment nuts dont line up too well with the chassis cutout on the infeed table, which leads me to wonder if the makers didnt intend for the beds to be raised to max extent when making adjustments. Finally, what am i supposed to do with these cam stops on the side of the beds? I dont think ive ever seen anything like that on a jointer, and im not sure what purpose they serve. I kind of get it on the outfeed table to always brin it back to exact height with the tersa knives, but i might be missing the point.
Thanks, apologize for my noobness on this one. I know its been covered before, but a few of my challenges are specific to this machine.
