Help with Jointer setup

[chopnhack]

Can anyone give me some pointers on jointer setup? I managed to replace the motor and reset the in and outfeed tables, from what I could tell somewhat satisfactorily... at least the scrap pine board came out equal in dimensions after taking several passes. But I expected the jointer to be quieter and smoother with the new motor. It is somewhat quieter, but still a little too noisy for a new motor. With no belt on, it is quiet and smooth, with belt....... I tried to align the pulleys, but what I found is that the two are slightly off alignment as checked with a torpedo level. If I correct them the belt starts to rub on the outside edge of the case! I tried to move the jointer forward on the base via its slotted holes and I maxed them out trying to move the belt away from the edge of the case. I also moved the pulleys on the shafts to get better aligned. Are their any tips anyone can share? And yes, I plan on getting a twist belt as soon as I can. The belt does seem to get hot fairly quick, but I am guessing that spinning at 3k rpm would do that. Thanks all.

A link belt will help but the is, to some extent, the nature of the beast. The cutter head is heavy and with three 6" or 8" blades cutting the air it is going to be loud. The same is true for a planer. I considered a link belt for my 8" Rockwell but don't think it would make that much difference.

Pulley alignment is going to be a lot of trial and error to find that sweet spot where the belt runs smooth on both pulleys and clears the case. Mine is on a shop built stand so clearance was never a problem.

Is this the correct replacement motor? If no then you might have to cut the case to make room so the pulleys can align. Another way is to alter the motor mount so the pulleys will align. If your pulleys have key ways, make sure they're aligned & tighten the set screws on the pulleys, I would use lock tite on em. Belt alignment & tension are important. Check all your screws, nut & bolts on the stand it might be loose and a possible cause of the noise. U can use lock tite on these fasteners so they won't vibrate loose. Last resort check your bearings on the cutter head. Hope this helps good luck....Jimmy

Thanks guys, the motor is a direct replacement, so I guess trial and error is the way to go. Its the vibration that really gets me. Its not so severe that you can't operate, but then again, its enough to worry about. I wll play with it some more tomorrow.

Sounds like the belt to me, Try the link belt I,m almost positive it will improve where you are now.
