Topic tags/keywords: dust collection delta flex tubing question small shop

I know there are a ton of post on LJ’s about dust collection, I think I’ve read most of them over the last week, but I’m still have some questions.

First, a little background.

My shop is a two car garage with all the tools in horseshoe shape around the center. A workbench, miter saw station, fridge, W/D, sink, deep freeze, and shelves take up pretty much all of the wall space, so most of my tools are not against a wall, unless you count the garage door.

I got a 1HP Delta DC with a chip separator the other day I’ve been racking my brain trying to figure out how to implement it with my shop setup. I absolutely do not want to move it from tool to tool, so I got some 4” ABS pipe a few joints that break off to a 2.5”. My current plan is to run two 4” feeds, each about 6’ in length (the advantage to my horseshoe setup). One goes to my TS with a couple of 2.5” drops for my OSS, Scroll Saw, etc. The other goes to my router table with some 2.5” drops for the DP, BS, and jointer. My bench top Grizzly jointer only has a 2.5” dust port but it seems to work well. Each of these tools will have blast gate to control the air: 4” at the TS and router table, and 2.5” gates at the other tools.

Now for my questions:

- I know this may not be the best setup, but will it work? One day I may move towards a 2HP like HF but it’s such a small area and I only use one tool at a time so I think it should be ok for now.

- I currently have all my tools on one circuit. It works, like I said I only use one tool at a time. I tested my iSocket with the DC and every tool can turn the DC on at the same time without a problem, I even tried it with a couple tools to see if I could trip the breaker, but everything seems fine. Will this cause too much wear and tear on the DC? I’d really rather not leave it on the whole time, it’s quieter than my shop vac, but it’s not quite.

- How do ya’ll connect your mains to your flex tubing? I found that my spare 2.5” shop vac hoses fit into the 2.5” ABS joint, but I’m not sure how to seal it. I saw Rockler has some adapters but I was hoping to go a cheaper route, like duct tape.

- The Delta DC has a bag filter that I’d like to replace with a cartridge. Does Wynn or anyone else sell one that will fit this DC? I haven’t had much luck finding anything yet.

- It also cloth bag on the bottom, would I better off using a clear plastic bag? I figure fine dust is escaping through there as well as the bag on top.

I hope this isn’t too much at once, but like I said, I’ve spent the last few days trying to figure this all out. Any help would be very appreciated! Thanks.

I’m going to get a copy of “Dust Collection Basic” this week to see if that helps. I was also wondering if there are any tips for making your DC quieter?

David, you will soon have the answers to your questions when you fire that thing up. The only thing I would advise is to not reduce any more than you have to. (2.5 inch will inhibit the flow) On the noise, well short of having the unit outside or in an enclosed area not much to do other than venting to the outside. The exhaust is where most of the noise comes from. What is your intake, is it 6 inch, if so I would stay with that as far as you can.

I have arranged my shop so that a 10’ length of 4” hose attached to my DC will reach my big machines – TS, jointer, planer, band saw, router table. The end of the hose has a plastic blast gate with a “quick connect” end (a bit larger than normal) that fits over a typical 4” dust port on the machines. Moving the hose from machine to machine is not really more of a hassle than opening/closing blast gates, I imagine. Previously I used a 6” hose and did get better airflow. Shop vac hose is 2-1/4” I think, but either way, 2-1/4 or 2-1/2, you will get only about 1/2 (or less) the airflow compared to the 4”. Seems to me that is too small for most of my big machines, although my Dewalt 735 planer is designed to work with that size, but it has a blower near the cutter to blow chips out the back.

I also have some 4” PVC drain pipe running along the ceiling. I “plug in” a drop, usually a shop vac hose, to reach my drill press, Kreg Jig, and table saw blade guard. Otherwise I slip caps on the “ports”. I have a 4” dust collector elbow fits inside the 4” pvc drain pipe (with several layers of electrical tape to tighten the fit), and then I use a 4” flex hose and hose clamp to go from there to the DC inlet.

See Wynn Environmental for information on switching to a cartridge filter. I just did this just last week.

Oh yeah, my DC is much quieter when I put my hearing protection on 8-)

Also, I have a remote to turn the DC on and off. I REALLY like that. Going to the DC to power it up or down was a real pain. I even wired up a remote switch I could reach from in front of my table saw, but that was not very helpful when I was using my other machines.

cabmaker, the intake is only 4”. The only tools I have that have 4” DC ports is the table saw (i added it underneath) and my router table “box”, everything else is 2.5”. Maybe I should run 4” to some of the 2.5” and just neck them down at the tool?

1st thing you should try to do, is put in a few more circuts if possible. You are gonna be in trouble trying to run a DC AND any tool together on one plug/circut. No matter what you do, I don’t think you can ever completely be dust free, well, unless you spend a ga-zillion bux for super equipment.

I scrounged 4 used shop vacs at the local non-profit building materials salvage store for $10 each. Now each tool has it’s own dedicated dust collector and I don’t have to run ductwork everywhere. A good collection hood is a large concrete footing form that is shaped like a big funnel. A HVAC sheet metal reducer gets the smaller end down to shop vac hose size. Noise? I wear ear protectors which I usually do anyway.

Roger, I’ve been a bit concerned about having everything on one circuit, but for the time being I don’t have much of choice. Maybe I can get another circuit added soon. It hasn’t been a problem so far, but I don’t realy want to push my luck either. Maybe that’s what I’ll do this weekend, figure out if there is more than one circuit in my garage and what the rating is.

I don’t expect to get all the dust, I just want to do a decent job so I spend less time cleaning up and there isn’t that constant coating of dust on everything. I’m also going to buid a couple of air filters soon, just need to find the time.

I plan on placing my blast gates within reach of each tool so as long as I remember to open them I don’t think it should be much of a hassle. The way my shop is setup, moving the DC from machine to machine would be a big pain.
