Hey All,
I just want to relate an experience I had yesterday in my basement
woodshop. We have a three flue chimney with a coal stove in the
basement (shop side) and our oil fired boiler which uses another flue
on the "not quite" clean side. This is also our laundry room and my
wife went ahead and ran a load of clothes in the drier because they
did not dry completely from being outside earlier in the day. Up
stairs is our woodstove which uses the third flue. We had a fire
going in the woodstove and all is going well. I was in my shop
marking layout lines on the legs for my dining room table when I
smelled wood smoke which I traced to the coal stove. I never had that
happen before but soon I realized it was the clothes drier removing
room air and the main source of make-up air was coming from the flue
of the coal stove. We rarley use the drier, relying mostly on hanging
clothes outside or nearby the two stoves to dry.


I never smelled oil fumes when the drier was used so it either was
never running when the boiler was firing or the air paths were not
affected. This just goes to show you that you really need to provide
make-up air if you exhaust your dust collector outside. A clothes
drier passes a lot less air than a DC but its results are almost as
significant. (My dust collector uses a large pleated filter so it
always returns filtered air to the shop.)

By the way, I am copying the design for the Hayrake table that was
shown on the Fine Woodworking site a few months ago.

Hope everybody's team wins today except for you Steelers fans. Go
Ravens!
