Topic tags/keywords: rollers jam

I have a 735, its a great machine. i try to clip any knots off the ends of the strips i plane, because i plane a lot of little guys. well, i missed one today and it exploded inside the there. it happens. by a fluke, a big chunk of the knot managed to wedge itself in between the metal housing that protects the cutter head and my front rollr. im having real trouble getting it out and i am on a deadline. if i seperated the top from the tables i could drill it our easily or cut it out but im not sure how to go about that. if i could pop the rollers out i could get to it too, and i found a post from a guy who replaced his roller bearings that might be helpful.
FYI, WD40 on your cutter channels is GREAT for removing pitch. i spray my tables with it too, and my carbide ripping blades on my saw. keeps things nice and clean

I’ve been checking this thread periodically to see if you’ve gotten any help (no clue from me!)—did you get it out?

Hopefully in the days once your post you’ve got this fixed. Regardless, my opinion – from me the not-to-mechanical genius in this bunch of jocks – if you can “drill” it out without damaging surrounding areas that might work. I would try that before I would tear things to far apart apart.

If it’s jammed between the metal housing and the front roller, it’s likely the roller drug it up to the point where it pinched. You should be able to roll the cutterhead backwards to drive the gear train and ultimately feed rollers backwards as well hopefully ejecting the knot fragment.

So my dad has the same suggestion, to drill the guy out. I raised up he carriage all the way but I was having s lot of trouble accessing the area. Anyone who knows a 735 knows there’s a safety guard there. It’s not quite enough room to get a Phillips in there, at least a standard sized screw driver, and those screws around the sprockets and such have a lot of torque on them. I was able to get the guard off after some tries. I didn’t want to spin a screwdriver in those over torqued screws and strip the heads, but in another classic leatherman victory, my leatherman came through for me.
Then I got the impact drill and started poking holes in the guy. After a half dozen I was making nominal progress but I (was) doing this for cash, so I wanted to get it going again and get paid.
I THEN proceeded to jam my leatherman tip in the drill holes and eventually got the chunk to disintegrate. Ugh, what a mess. I probably could have popped the roller out, but dad taught me not to take things apart if you don’t know how they go together, and I was also concerned the jam was severe enough the roller would come free without messing it up anyway.!

So I got the guy out. Reassembled my planer. Turned it on. The rollers spun! Yes!!!!

But no. When I attempted to run a peice, my rollers lacked the HP to pull wood through. I use this guy ALOT, and I know about clean rollers and clean tables and all. For kicks I checked my sprockets but I already knew it could only be one thing: stripped gears.

Fortunately it’s still under warranty. Dewalt has great customer service and they don’t care if you are using s machine commercially, so I love them for that. Other companies (craftsman) have shut me down on warranty questions once they find out there’s a commercial application.

So she’s in the shop now. Should be three week turnaround. The lesson: when planing pine in small strips be SURE to cut out any catastrophic knots
