Good day.

Too many chips get past my Super Dust deputy. I would like some input.

20” powermatic planer
Planing 2×6’s that we’re left over from my shed build. Going to use them for a shelf under my tablesaw extension wing to hold a fence or two.

4” PVC routed from the SDD to the planer. Soft hose the last bit of the way to the planer and from the SDD to a 55 gallon dum. Venting outside to 2 4” ports.

Everything appears to work great. Lots of suction at the machine, chips in the barrel. Still lots of chips outside the shop. My wife noticed it and I looked in my barrel and was just over half full so I emptied it, cleaned up the chips outside and went back to planing. A couple more 40” boards later and there’s a layer of chips outside plus some in the barrel.

I literally hate dealing with DC stuff. I thought, for a hobby shop I was doing things pretty well the way it’s supposed to be on a budget. It really should work and seems to have worked in the past.

So, am I taking too much off? It’s construction wood pine. I am carving Off a lot compared to the normal hardwoods. Still not sure why it wouldn’t work still if that was the case but maybe you all know something I don’t?

You quite likely have a leak in your chip container lid or the mounting of your SDD. Mine lets almost nothing get by it except sometimes some confectioners sugar sized sawdust and even so little of that that I have to look hard to find it.. Get a can of smoke test spray like they use for smoke detector testing and spray it near the joints between the lid and container, and also the SDD and the lid joint while the dust collector is running. If there is a leak, the smoke spray will get drawn into it. Incoming air will cause turbulence in your chip container, allowing chips and dust to get past your SDD and on to your secondary filter. Believe me, they work incredibly well when there are no leaks.

Lighten up the cuts and see if it makes a difference. Bigger chips and lighter weight chips could be the problem

Maybe a picture of your setup would help.

Charley, that was my wife’s guess too. I’ll try the smoke test. I don’t have clamps on the lid because I can pick up the barrel with the DC on. I’m definitely not on here to bash the SDD. Hell, I bought it because of the extensive reviews and I believe them. However, this hasn’t really been an issue before unless I let the barrel get too full so I think you’re on to something.

Dan, this is pine so I don’t think the chips are heavy compared to what I normally plane but it’s a thought.

Bill, my setup has worked in the past well so I doubt it’s the setup. Charley is likely right but just in case, here’s a pic, besides, we all love pics.

I would think if a leak is the problem, it is somewhere below the deputy….a leak down there would cause air to rise up thru the deputy and take chips with it.

I agree Bill maybe when I emptied it I didn’t push down enough to get it set on. I’ll run a smoke test and likely get some clamps for the top. Right now it’s two layers of plywood with a bike tire around the lower one to seal it.

I have a similar setup in that the weight of the lid and suction is what seals it, no clamps. I have a wide piece of stick on foam seal on the underside of my lid.

Yep. Smoke test (incense). A six inch board is a six inch board and twelve inch boards don’t create enough chips to get past my SDD.

I solved my seal problem by using the straps trucks use for their engine covers.

My SDD has, since this picture, been switched to my 3hp and it’s been running for a couple years. They only thing that gets past the SDD are plastic bags, fluffs of insulation and other things big-and-light.

It’s happened a couple of times so I think you all are on the right track. I just got back from the store with the wife to get incense and we forgot the incense. Go figure. I’ll head out this week. Tomorrow morning I’ll just throw some weight on it and see if that works and I’ll get incense this week if needed. This little project isn’t a fun one really, just a necessity so I kind of just want to get through it. I’m almost done milking stuff down. I’ll update this for future reference (read: when I forgot the solution to this problem in five years and do a search).

Are your blast gates on the manifold or at the tool? At the manifold will help your flow & static pressure.

Thanks Mark, mine are all where it divides off to the tool like yours, before they turn into the flex hose.

In my rig the plastic slip on connector were also slip off when the fan is pulling. Tried several methods but finally had to X cut the ends and snug em all down with metal clamps. Had to go to metal blast gates as the plastic ones just came apart. Each change alone made things a little better. It took months of tinkering (+$$$) to finally get it right.

Yeah, I definitely want to go to metal blast gates because I think the plastic are garbage however, there is severe suction at the tool. I tested a couple tools and it’s pretty strong for sure. Very scientific test of putting my hand over the hose. Obviously things are working on the suction side since the chips are flying out of the shop. I hate tinkering with this stuff. I like tinkering but hate the DC thing.

I had two of my systems set up with metal blast gates and sloping Y’s and could detect the drop with each mod. Finally, I just ran a separate hose to each machine and swapped the hoses, rather than open and close gates. That improved the system greatly and it takes no more time or effort than the gates.

I have eye hook in the ceiling with small pulleys though which ropes run to two different units so they remain at about chest level, the level of the port, and it’s easy to swap things.

Just saying I have the metal one, Grizz 2 HP on it, NEVER any thing like that, I did notice I got that plastic one and returned it, it had gaps between the outlet and inlet pipe, I was afraid of cracking down the line even though the plastic one’s design looked better
I put the Grizz blower on top of the cyclone then to the separator, man dust succer ,AND separates

seal it up or get the metal one
