I am getting a series for small indentations when planing soft wood like pine or cedar. These appear to be caused by the output feed roller. There is no problem with hard woods like white or red oak and even poplar.

I have read a number of topics dealing with DC with the 735. People have used either a real dust collector or they have used garbage cans in some configuration. I do not have either the room or the desire to buy a real DC so I have been trying the garbage can route.

My problem is that even with a Woodcraft garbage can lid attached to the planer and another garbage can with a homemade lid attached to the first can which is then connected to a Ridgid “shop vac” there is so much air being moved that the Woodcraft lid must be held on with 2 ratcheted hold downs. I am still getting enough back pressure that some of the chips are not cleared and gather on the feed rollers or the board being planed. By the way, the tubing between the planer and the first garbage can and from the first to the second can is 4” clothes flexible dryer tubes.

Are these indentations something to be expected with soft wood when not using a 1400 cfm DC? I cannot believe that using the garbage can solution will eliminate back pressure so that all of the chips go out through 735’s blower. I even found people who use only small bungee cords or use non clamped fittings with a pillow case as the final resting place for the chips.

An associated question deals with cleaning the rollers. How can I completely clean them since they cannot be turned without taking the top off of the machine and manually move the cutter head?

You need to have a way for the air to escape your trash can… like a cloth sleeve. This will solve your problem I think. No longer available is a sleeve to fit your trash can on one end and a four inch hose on the other. I had one and it works well but makes your shop dusty. A shop vac will fill up much too quickly to be convenient. I now have mine hooked to my dust collection system.

I am afraid that I did not make my configuration or my questions clear. I have a Woodcraft garbage can top hooked to the 735 to simulate a cyclone. The output from that container is directed into a home built trash can top via a 4” flexible hose. The output from the second container is connected to the shop vac via a 2 1/4 ” hose. The shop vac should get very little input since the vast majority of the chips are left in the first container with some in the second. I have tried screen and cloth filters to replace the shop vac input hose still with bad results. There is still enough back pressure to keep the 735 from ejecting all of the chips. The few that remain then appear to be pressed into soft wood with resulting indentations.

My questions are:
- Am I possibly getting more then the normal amount of air moved by my 735 since others have indicated that even a single container with a cloth sack attached works?

- Do I have to live with these small indentations in soft wood if I do not want to purchase a DC which moves 1400 CFM (needed according to DeWalt)? They obviously can be sanded out. Does anyone else have this problem?

- How can I clean the rollers on the 735 when they cannot be turned without removing the top and the internal cover over the cutter head?

The only way I’ve been able to clean the rollers completely is to clean what I can, jog the motor, clean again, repeat as needed.

This has also been my experience with roller cleaning. I don’t have the issue you describe though; how much depth do you typically remove, and what width boards are you planing?

Even a big shop vac won’t keep up with the blower on a 735. You have a separator, and another garbage can, but no large filter correct? The air needs to escape through a bag or pleated filter. The air cannot escape so it pops the lid off.

The filter on the shop vac lets some air escape, but not nearly enough.

I have a small single stage dust collector on that planer, and collection is quite good.
Take the lid off your planer and check for broken plastic parts. One clue is the inside of the planer will fill up with chips, making the handle hard to rotate. I have replaced both the shroud and fan blower assembly. When those parts are cracked or broken, dust collection becomes poor.

Good luck finding a simple fix to your dilemma.

This is a good option and it works very well.

When using my DW735 I use a crude “Thein cyclone” dust separator made from a large paint bucket and a home depot bucket with a Thien baffle between them with a shop vac and it works well. I did upgrade the filter on the shop vac to a Cleanstream Filter to make it easier to clean the filter. If I forget to turn on the shop vac, the bungee cords I use to hold the 2 buckets together allow air and some dust to escape but it still catches most of the chips and doesn’t seem to prevent the planer’s blower from clearing the chips, even with 16’ of hose.

It’s ugly but it works great:
