[TheForge] flues

[Ben Barrett]

This is a great conversation, guys, thank you all -- I have an
additional question as I am also developing my plan to install a flue
pipe.  In my shop, I'd like to pipe a small woodstove and my coal
forge's flue together, so there is only one hole in the roof.  I was
figuring that the most sure-fire (heh) way to maintain a good draft on
either or both would be to make a good-sealing damper on each pipe
below the "Y" piece that will bring them together.

I am planning on having the Y joiner just above the forge hood (which
will have a drop pipe too, I hope, if I can fit it, so prolly above
where the drop pipe raises up to), but still inside the shop.  This
joiner is the only horizontal dog-leg I can foresee in my plan.  Is
there any good or bad luck folks have had with sharing a flue like
this in their homes or workshops??

thanks!
