venting my new forge

[andreas]

I am rebuilding the little forge in the pictures. Basically scrapping everything but the blower and rebuilding to roughly the same dimensions, except square and a little taller. If you look in the other picture of my shop, I want to put the forge in the area under then window, build a hood over it and run the vent/chimney pipe out the window. My question is, will the hood still draw well enough with two 90 degree bends in it (to get the vent outside)? Anyone else have a similar setup, what did you do?

How high of pipe will be outside of the window? How enveloping will the hood be? What will be the gap between the pipe in the hodd and the forge table. What size pipe will you be using?

Basically we need to know a lot more details between saying Yes-No-Maybe!

Put your pipe on a 45 degree angle use 1 45 elbow out side.
you don't need a hood at all. I had a setup like that for years
it worked great if you will burn some newspaper in the mouth of the pipe
before you try to start you coal fire. I got this idea from Walt Hull.
He had it for a long time. super simple, cheap and it works good.
Make sure you have plenty of pipe out side to clear anything
within ten feet of the pipe.

Phil, I agree. I've used a horizontal 3 foot run of 10" through the wall and a 90 degree outside with great success. Used some fire brick for a surround for the pipe to act as sort of a funnel. In total it acted as good as any fancier arrangement that I've had or seen. Simnplest is often bestest. :-)

What the Peacock, I'm guessing is Phil, is describing is a side draft hood and it will work much better than a large over head forge hood.
