Topic tags/keywords: jointer joining question

I purchased 6” poweramtic jointer off of CL a while back and am just getting around to setting it up. It came out of a school shop and had a 3/4hp 3ph motor, I changed it over to a 1.5hp 1ph motor, both are the same speed. I just put new knives in and am having trouble with excessive tear out and the cutterhead wants to grab the workpiece and pull it forward. I’m not real familiar with setting up jointers so any help is appreciated. The depth of cut is set about 1/16”

The cutterhead wants to pull the workpiece FORWARD?? Which way are you moving the workpiece?

From the infeed table to the outfeed table (R to L, when facing the jointer)

gavo, congrads. on your find. The early powermatics were very nice machines. Dovetail ways no doubt. Your info. is a little sketchy. Are you asking how to set the kinves? If so, basically the top of the arc will set with the outfeed plane. You also mentioned the the cutterhead was trying to pull the work forward. That concerns me. Is the motor running backwards? Can t answer the tearout issue without knowing a few things to wit: wood species, grain orientation, proper knife installation, knife grind,etc. Good luck with it JB

From the same perspective, what direction—clockwise, ccw, is the cutter head rotating?

Sounds like it might be a wiring issue? If the cutterhead is pulling, then the motor is turning the wrong way.

Steve and Lee asked my next question. – lol

When you’re pushing the workpiece, is there any actual cutting – or just a lot of banging as the cutterhead hits the board?

You guys are correct the motor is rotating the wrong direction. I pulled it out the other day and it says that it is non reversible, so I just ordered a new 1hp Baldor motor.

Have your say...
