Topic tags/keywords: question mahogany planer resource

I picked up a Dewalt 735 planer 2 months ago. Recently I was running some mahogany lumber through it and the feed wheels starting slipping and not feeding the lumber through. They are functioning correctly otherwise but they seem like they can’t get a good grip on the lumber to feed it through all the time.

Sometimes they work and at other times they don’t. Although they are always moving.

Has anyone else had this issue? Know of a fix or am I doing something wrong here?

Just to eliminate some suggestions
1. I’m not taking to large of cut usually only 1/32 or 1/16 at best.
2. The rollers are clean nothing on there.

Check the height of the infeed and outfeed tables. If they are not on plane with the actual “work surface” of the cutter heads this might cause a problem. (co-planar) . Another guess would be to clean the feed rollers with denatured alcohol. Mahogany is fairly oily and they might actually be slipping. I know you noted that they were “clean” but . . .(Visibly clean v.s. Actually clean)

Also, do you notice any additional snipe at the ends? Does it happen only on long stock? Only on thin stock? Does it occur if you INCREASE the depth of cut? Any addtl. info could help to nail this down.

Ihave the 735. The problem you describe is usually my first indication that the knives are going dull, or they are loading up. My first step is to follow Grumpy’s suggestion and clean the rollers, if that doesn’t get it, pop the top and remove the blades. If they are loaded, just clean them up and reinstall, if dull, rotate and use the other side.

Great suggestions I’ll get into these tomorrow.

1. No snipe
2. Length doesn’t matter happens on all lengths

The rollers are slipping because when it stops moving and i have to push the lumber to get it going again i see a small amount of rubber dust almost like a little burn out.

i have an older ryobi that does the same thing. When it does this I know it’s time to give the rollers a good cleaning. they will load up with dust and oils from the wood. you can also try waxing the bed of the planer with a furniture wax. the bed will get small scratches that may catch the wood. I’ve tried to get into the habit of cleaning my planer after each heavy use to keep this from happening during middle of a project.
I clean the rollers with Krud Kutter from Home Depot. IT’s also great for router bits and saw blades.

I have a newer one in good shape and this happens once in a while. I always stand by to “help” a little. I think it just depends on the smoothness of the board as well as some of the other things listed earlier. With a little dust and a freshly planed surface certain types of wood will tend to slip a little.

Well it seems that it was just the mahogany i was running through there. I ran about 20 feet of walnut and poplar tonight and didn’t have any problems. Only once or twice it slowed up so i just nudged it and it kept on truckin.

I’m still going to break it down in clean all the internals.

Thanks for all the help guys lumberjocks rocks!

as an aside, you might also try cleaning and then waxing the tables with either paste wax, top-cote or some such . . .once it is applied and completely dry you shouldn’t have any problems with whatever finish you apply. You’ll probably sand, plane or scrape before finish goes on any way.

My dad has one of these and has had it in the shop three times for this issue. We tried planning up a about 12 90” long 5/4 boards this weekend an got to the 3rd board and it started do the same thing described above. So he took it into the shop today, and the service manager agreed to replace it and should have a new one by next week. Needless to say he is tickled pink. Hope you are not having the same problem that he has had.

I have same planer. I have had the same problem. Take some thinner and clean the rollers by raising the head to the highest point. change the knives that will help. More often the blades are starting to dull.

Same planer – same issues – same answers:
  1. Rollers may be dusty – clean with mineral spirits
  2. Knives may be dull – use second side or replace
  3. Bed may not be slick – apply paste wax

For me this problem is most pronounced with mahogany (dusty) and hard maple (knives must be really sharp).

DeWalt service centers have excellent help – both live technician and videos of common routine fixes.

OK it’s official, I had the same problem until today. That’s because yesterday I raised the planner to the max. Then I used lacquer thinner on the rollers. They were nasty, but today they were clean. Today the planner worked like new, and not one piece of wood bodged down. Do this before you mess with the blades.
