More Dust Collection

[jackellis]

I thought I had my DC piping choices all sorted out until I went over to the local Borg tonight for some 2x6 KD lumber. While there, I found out that a) Home Depot doesn't carry 2x6 KD lumber, b) ABS pipe is only available up to 4 inches and it's not cheap, and c) 6" ducting runs about $1.50 per foot.

The only drawback I can see with steel ducting is that you have to caulk the seams, which might be more trouble than its worth. For 6" waste pipe, looks like I'm going to have to try the plumbing specialty shops.

Does anyone know whether Lowes typically carries what I'm looking for?

My Lowes usually only has sewer and drain varieties of pipe up to 4", although they carry pressure-rated PVC (way too expensive) up to 6". Instead of caulking the seams of steel ducting, have you considered a good quality duct tape instead?

I was thinking the same thing as UC about the tape. There is tape out there that contractors use on HVAC ductwork that has a mastic backing on it & a type of foil on the outside. To get a larger diameter pipe, you might want to try a plumbing supply company.

6" Waste Pipe

My Lowes usually only has sewer and drain varieties of pipe up to 4"

In St. Louis, some of the Lowes carry 6" green waste pipe and some do not. They are 10' lengths. Plumbing supply houses have the 14' lengths w/ gaskets in the bells. I bought the pipe and most of the fittings from a supply house, got a quantity discount (I think for 3 sticks) and it was delivered free. There's another place here that sells by the foot, good if your main is short.

I use sheet metal for multiple reasons, it is fare easier to put up, is lighter, seals better, can be connected to very easily, and is grounded by default so there is no danger of static sparks. http://www.bt3central.com/showthread.php?t=43926 has some pictures and discussion about how to seal metal duscting. Also see the pictures in my response on that thread

If you are going to use 6" ducting, you will want to find a cheaper supplier than either the Orange or the Blue Borg...

$1.50 / foot is awfully expensive. Check your local Ace Hardware, as well as other vendors. It should be around $.75 / ft.
