DC system setup

[venkatbo]

Hi folks,

I got myself a Delta 50-760 1.5HP Dust Collector for the garage wwshop.
'am totally clueless as to the design and setup of the piping, Y-splitters, etc., to hook this DC system.

Could someone point me to resources on the design such a system. I don't think assembling the Delta 50-760 would be an issue... just all the other stuff that needs to be installed before hooking up the Delta 50-760.

Thanks,

venkat,

Have you decided what kind of piping you want to use? I'd suggest 4" S&D PVC, due to it's appropriate size, low cost (for pipe AND fittings), and because it works well with other DC fittings.

You can make a "main line" from the DC to the farthest tool, and then install "drops" to each tool from there. The picture shows a wye connection, which is a good way to branch off a main line. Use another 45 degree elbow to make a full 90 degree bend.

This picture will give you a basic idea of how to connect 4" DC hose (Rockler, Woodcraft) to the 4" S&D. The metal blastgates are a good fit into 4" S&D, and the S&D, in turn, is a good fit over many 4" dust ports on tools. Put blast gates on each drop as close to the main line as you can.

Try to minimize the # of elbows, and use large-radius 90's when you can.



Uhhh, disregard the 3" PVC plumbing behind the 4" S&D.

Tom

Thanks Brian & Tom.

Tom, pardon my ignorance - but what does S&D stand for :?)

Hey guys, I'm at the same stage regarding DC system.
I took a 4" adapter (one end the hose fits on and the other end fits over the tool outley) with me to HD and I can't see how you get 4" S&D pipe to work
the big end of the adapter is the same OD as pipe.
Now I didn't take flex with me. will it fit over the pipe?

Tom, what is the green piece you ahve the hose attached to?

Venkat,

Where did you get your new DC? I've been holding out for a decent sale for the 50-760 but nothing so far. Did you get a deal?

Thanks,

Vinh,

I got this a while back for ~$175 or so cant recall properly... Just getting
to hook it up.

If you have the patience, you can get the HF model and add the 1micron
bag - search the forum for the 1micron-bag supplier. It's come to ~$155
or so. <=1micron is highly recommended for healthy lungs :-)

That green piece is just a short section of S&D. If you have a fitting that is the same OD as S&D, then you could use a PVC coupler (used to join 2 pieces of S&D). OR, since a 10' piece of S&D comes with a ~6" section on the end that's oversized to slip over the next piece, you can use that portion to couple.

The flex hose that I get at Rockler will just fit snugly over S&D; usually I remove a few winds of reinforcing wire, and add a hose clamp like in the picture.

(Note that the fittings for S&D are different than for Schedule 40 pvc.)

Tom

Tom, as I recall, you use Schedule 35 S&D, correct?

So disregarding the 3" plumbing, any reason you used pvc before the s&d pipe? Any reason not to do the same (possible access).
Thanks

Thanks Tom.
I realized that I answered my own question after I wrote that.
this is what I was talking about and it looks like it will likely fit the belled end of the fittings for the PVC and the flex screws right onto it.

I'm not quite following -- which PVC are you refering to? The wye? Any reason not to do the same as what? (Sorry, major case of brain-dead this AM.)

Brian (Knuckles): Yep schedule 35, aka SDR35, or ASTM 3034, which is ~1/8" wall thickness for 4" diam. There's also thinner-wall stuff out there, ASTM 2729, at a bit over 1/16" wall. That stuff is probably too thin. (SDR stands for "standard dimension ratio", the ratio of wall thickness to diameter, with some multiplication factor. A given SDR will have the same pressure rating, no matter the pipe size, as bigger pipe will have commensurately thicker walls.)

Brian (bigsteel15): Right, if a DC part doesn't fit inside the S&D pipe, it'll probably fit inside a S&D fitting. And then getting it connected to the pipe is a done deal.

Tom

This time I wrote it down. I knew you posted it before, but each time I tried to search for it, I couldn't find it.

I was in the Eden Prairie HD tonight. They have the SDR35 in an attractive gray color.
