I'm amazed at the variation in pricing and options for putting all the
mechanical in for my dust collector in my small shop. I have 6 tools
I'd like to collect from and a 3HP G0441 dust collector from Grizzly.
I've gotten quotes for spiral pipe and snap lock (hvac) pipe that range
from $175 to $600. I've talked to local installers and they want $95
an hour for labor !
I know the snap lock pipe (if I'm using the right terminology) is
suppose to be more difficult to work with but have no idea how much so.
Grizzly's piping is outrageously expensive and the sales people at
Oneida I've found to be knowledgeable but pushy. Last I spoke to them,
here's a quote "I'll design your piping for your Grizzly system (I
never told them I bought a Grizzly), but it'll cost you $400". Not a
business winning personality if you know what I mean.
One concern w/ less expensive pipe is for each of the Wye's that go to
the individual tools, I want a sturdy place to be placing the pipe
clamps for the flex hose.
Any and all advice greatly appreciated.
Oh man, don't buy that spiral pipe for a home shop. Way too much buck
for no bang.
I bought the snap pipe from HD (the thicker stuff... they had two
locations in the store). Works great.
You can see it in action on various tools in my shop:
Great shop I'm jealous of the room!

I recently did some duct work and found that snapping the pipe together
first, then using my sabre saw with a metal blade worked much better than
the snips. Was much quicker and left a smooth cut.
Wow, I wish I had thought of that. I did some metal duct work a while ago
and used up a large supply of colorful vocabulary cutting the pieces. Your
idea sounds like a winner compared to what I went through.
Nice shop - I am envious of the space.
A couple of the shots looked like my pictures from a couple of years
ago - the pegboard shot, for instance. I did a double take... ;-)
It's long gone, however, having had to rebuild the walls and ceiling.
Suppose I'll have to put up a shop page one of these days...
I have a few badly outdated projects pages and a CAD rendering of the
shop, but no pictures...
the snap lock is easy to work with Just wear gloves to avoid accidents. Do
not use the thin stuff at HD, if they have the heaver stuff get that.Do NOT
use HVAC pipe (for the wyes) purchased at HD. look for a local industrial
woodworking supply store near you or go to http://www.airhand.com I just
went though this I my home shop I read all the opinions and different web
sites on materials and finally bite the bullet and purchased four hundred
dollars worth of pipe ,wyes,flexible hose ,ect to connect 8 machines
good luck and be careful puting in the system
I took the cheap route: 26 gauge snaplock pipe from HVACommerce.com
($5.66 for 5" x 5'), "economy" 26 gauge fittings from Penn State
Industries, and I installed it myself. The snaplock really isn't hard
to work with - there's a bit of a trick to snapping it, but you'll get
the hang of it after a few pieces. Definitely not a $95/hr skill level.
As far as attaching the flex hose, you'll amost certainly want a blast
gate at each tool, so the hose will usually connect to the gate, not
directly to the pipe.
$400 for design? Humph. This ain't rocket science, and you don't need
CAD drawings with 0.001" precision. Spend $20 on a decent book, and you
can do the pressure loss, airflow, and air velocity calculations
yourself. If you don't feel like doing the math, it's a fairly safe bet
that 5" pipe is the right size for an average hobby shop, using one
machine at a time.
Oneida-Air will do drawings for $50. It is free if you bought your dust
collector from them. They will also credit the $50 if you buy in the
I don't know what they will do if you say you want plans for a different
brand collector. I would just pick the Oneida-Air model with the closest
airflow to your collector if you want them to do plans for a non-Oneida
I got a great deal from a small local sheet metal shop on the y's
(6-5-5, 5-5-4, 5-4-4) and heavy snap-lock I needed. Sorry, can't
remember now what he charged, but after looking at Grizz and Oneida I
about fell over at how cheap he was in comparison. You might get a few
specs together and call around locally.
