Hey guys,

I’ve had my dewalt 735 planer for a while without problems. Lately, the left side (from feed side) is cutting just slightly deeper than the right. Very small variance, but it is there. Measuring up from the planer bed to the knives, it seems that they are the same height. any ideas or did this happen to anyone else? Also, i went through a spell where chips were collecting in the inside making it hard to crank at times. got that taken care of but now have this. Any help is appreciated.

Ross

No problems yet as one described yet. I can relate to the chip problem, maple chips have been a problem, clogging the blower duct and in an around the crank. Just keep it blown out w/ compressed air.

Has it been a consistent problem, or did some chips get caught under one side of the board?
Are you using a dust collector?

Its been more of a consistant problem. Actually if i run narrow stock under the right side and without lowering at all, run again on the left, it will take another small amount of material off. Any chance its the blades you guys think?

Is it possible the knives are just duller/more worn on that side??? As you probably know already, the Dewalt knives suck, and don’t last very long.

A few weeks ago, a guy had a similar problem and it turned out that at least one knife had moved. I would take the knives out and replace them and check it again.

I don’t see how the knives could move on the 735. They are fixed in position by registration pins. They will move side to side a bit, but cannot move up and down.
Check the manual on how to adjust the cutterhead carriage.

it only take for 1 knife to move or lose it’s edge for abnormalities to start happening. it seems like it’s time to rotate/replace knives

I’d suspect uneven knife wear. My Delta says to feed across the table. You probably have adjustments on the infeed and outfeed tables but I think the middle stationary table is pretty much fixed left to right in alignment to the feed rollers.

”...Also, i went through a spell where chips were collecting in the inside making it hard to crank at times…”
\///////////// I had this same problem and found the cause. When planning cedar a large piece of wood broke loose and was chopped up in the discharge fan. This broke the impeller and the case of this fan allowing sawdust to get into the planer and jamb up the thickness cranking mechanism. I had to replace this fan. (twice) I now keep a spare discharge fan on hand.

I was also thinking a nicked blade would leave a ridge on the board. When you flip the board, the ridge holds the board slightly off the planer bed and causes a slight side-to-side taper.
So I think you are on the right track replacing the blades.

I can speak to the chip problem. The back of the impeller housing wears out fairly frequently, allowing the chips into the case. The two halves are cheap and easy to replace. I have three 735’s and run them ALOT!! I keep extra housings on hand, and find that they wear in about a year in my shop.. that would be an est 20,000 board feet or so. The wear is almost indistinguishable to the naked eye. Replacement does require removing the impeller, but is not hard.
