I picked up a Dewalt 735 on sale at one of the local tool stores. For $550 I couldn’t refuse. I built a table taking ideas from the site. My thanks to all who went before me. Right now I’ve got it hooked up to a 2 1/2” hose to a Thien cyclone to a shop vac. It ain’t happenin’.
If I cut a 4” hole in top of a plastic garbage can and hook it up to a 4” pipe ( no shop vac), will that work?
Thanks .

I’m not sure what you mean by “it ain’t happenin’”

But I think I can take a few guesses….

1. Planing generates a LOT of debris – try keeping the aggressiveness of you cuts to a minimum – meaning; try to take a little off at a time – don’t get to crazy

2. maybe you need to extend the 4” portion of you vacuum line (36” to 48”); it might help spread out the debris stream

3. Can’t tell from the photo – but it looks like you can use a bigger can on your cyclone set-up; like a said – planing generates a LOT of debris

you’ll figure it out

If I understand correctly you are talking about hooking it up to a garbage barrel using a 4” pipe with no suction and hoping that the debris will land in the barrel. No, I can’t imagine that this would work, as I think it would quickly clog. You will need to hook up a dust collector with some decent suction. You might be able to get it to work a little bit if you use a shorter run from your shop vac. Before I hooked mine up to my dust collector I had it hooked up to a 5 HP shop vac with a 6’ hose and it worked borderline ok. I had to unclog it every now and then, but for the most part it would keep up with the planer if I took light passes on narrow stock.

But, I would look to add a dust collector to your collection soon if you want to effectively collect from a planer.

The 735 expels the cuttings pretty well. I’ve used mine both hooked to my shop vac and with the cloth thing it came with around the top of a garbage can. Both ways worked just fine. Did yours not come with the cloth can-topper-thing?

The shop vac obviously fills up quite quickly, so be aware of that and empty frequently.

Planing doesn’t create much dust but does create a ton of shavings. You don’t need to go overboard with a DC system just for planing.

Get some 4 inch flexible hose and make a Thien separator with 4 inch PVC. You don’t need to attach any sort of suction to the cyclone, the 735 blows chips right up the 10 foot hose and into the separator. I bungee some muslin to the middle hole of the Thien and it works like a champ. Made my Thien cyclone from some construction grade plywood to fit into a Rubbermaid Brute trash can.
Your big problem is using 2.5 inches. I tried that as well and it spat chips out the front of the planer, even with suction from a shop vac. Air flow was restricted too much. Maybe I’ll post some pics of mine as a project soon.

The way I see it you have two choices. You can either get a dust collector or you can get a broom.

Run a 4” hose to the separator and then you can use a 2” hose
and vac to pull the air through the other side. I used this sort
of setup on and off for years for planers.
