Dust collection questions
I am about to upgrade my DC, prompted by buying new equipment recently.
The 1hp H&F dusty I bought a couple of years ago did a sterling job with the
Triton and my 12" GMC thicknesser, but struggles a little with the new
tablesaw and struggles a lot with the new 15" thicknesser.
H&F have a deal at the moment of a DC-3 dust collector with a FC-10 1 micron
filter cartridge for $458 complete with 10 plastic collection bags.
I have 2 questions.
How loud are these 2hp dust collectors compared to my 1hp, is the difference
in noise level really noticeable?
I am going to run 100mm sewer pipe ducting, running overhead. Is it OK to run
this uphill away from the DC, following the roof line. The DC will positioned
against the shed wall, the pipe will run to the middle of the shed following
the roof slope, then come down between the tablesaw and the router table.
There will be a t-joiner above the table saw, coming down to the guard and
stepping down from 100mm to 65mm.
I am still deciding on whether to build a small cyclone or just go for the
2-stage approach that other forumites have adopted.

Hi Big Shed,
I cant comment on the h&f 2hp dc but the carbatec 2hp one that i have handles the 15" thicknesser not a problem. I do have a cyclone of sorts as well but it is mainly to collect the shavings.
Another forum member commented to me about running 6" pipe instead of 4" as it boosts air flow somewhere between 20 & 40%. All I have to do is remove the inlet pipe fitting on the side of the dc.(it steps down from 6" to twin 4") You might be able to get away with just going up a size in pipe instead of upgrading everything. I would probably try a length and see how it goes before you lash out and buy a swag of new gear.
Saying that, if I was going to run the pipe permanently across the ceiling I would most likely put the bigger size pipe in the first time.
Shane.

Just being technical but I think your running it TOO your DC not away.
Been pricing that sewer pipe and it aint cheap esp. compared to storm water pipe bugga bugga *^#*@*^#><*I would love to grow my own food, but I can not find bacon seeds

I dont think it would be much louder

I have run 6" (150mm) to the middle of the shed roof and dont have a problem, My duct does slope towards my cyclone

Big Shed if you havent already you may want to have a read of Bill Pentz's site. http://billpentz.com/woodworking/cyclone/Index.cfm
I upgraded my 2HP dusty for a cyclone and I just love it, I no longer have to worry about the fine dust that used to come of the bags each time I started the dusty up. Here is link of my cyclone. http://www.woodworkforums.ubeaut.com...ad.php?t=31169
Have a look at Dust Collection section in the Best of the Best there is a lot of good info and ideas that other forum members have contributed.

Investigating cost of 6" pipe and fittings, might make main run 6".
Am a frequent visitor there at present.
Yep, have read (and saved) your thread several times, also the pictures.
Great workmanship, would never be able to emulate that.
So your 2hp dusty is still the unit on top of the cyclone? I take it you
exhaust straight to outside without further filtration?
That is not an option in my case as our rainwater tanks are there!

Have read all of those and more, thanks.

Pat, I know my abilities, faith has nothing to with it. I am positive I couldn't build Al's duct work, let alone the fittings
I am not a metal worker, never have been and never will be.
It is noisy stuff and it stinks

ok, adapt his design, utilising the plumbing bits and pieces to make it work. 100mm sewage pipe, is it plastic type. Therefore elbows can be plastic. Depending on your budget you should be able to do what you want to do. No fine dust from any of your machine toys

Yep I know I can do the plumbing stuff, did all the sewage pipes around the house, for plumber to inspect.
Plastic is easy, and with the duct work I won't even use glue.
It is metal that doesn't like me
