Someone is giving me 15 feet of pipe, 15 inch in diameter. My question is could I make a side draft hood out of it then have the remainder to be the vertical pipe off it? my fire pot is 12in by 12in.

of course.

only on days that end with "y"

Like this wonderful skitch I have attached?

reason being is I don't want to put a hole through the roof if I didn't have to, so if cutting the pipe and joining them in this fashion would work, then that's what I'll do.

The rough sketch is what I meant, I see square box type at the fire pot through the wall with the round pipe attached vertically so I'm not sure if I'm wasting my time using the round pipe at my fire pot then run it vertically off it.

I don't want to put a hole through the roof if I didn't have to, so if cutting the pipe in two sections and putting if through the side of the shop would work, then that's what I'll do.

I still have the 55 gallon barrel and if using it as my hood and then run my 15in pipe straight up off it through the roof would work better, then I'll do that. I need to know which way would work the best because I screwed it up the first time and I do not want to get smoked out again.

Your sketch looks like Hofi's setup from the missing blueprints. Maybe Glenn will make the blueprint(s) in question available for you to look at for a day or so.

Hi Ledson,
My sidedraft is loosely based on Hofi's design, and very much like your drawing as well.
I'm well satisfied with how mine performs.
Hofi's side drafts are really nice, while mine was built from what scrap I had available.
It still works GOOD.
There are a bunch of pictures in my gallery showing how mine is made.
Good luck, James

I'm using the Hofi syle side draft . I have never had a problem. It draws very well,I never have any smoke inside the shop,it's very simple.
