Oren, a furnace fan is normally in a closed structure and the air flow is
restricted by opening sizes. RBM asked you about amp draw as this is
what you need to NOT exceed or you will toast your motor soon. I've made
quite a few of these for different people/reasons. You'll be really
close if you close off one side of the fan with a piece of peg board, the
other side can remain full open. The amp draw will be really close.

Restriction should lessen amps.

Using this idea to restrict the air flow into the blower, could I get
/ go back to the high-speed (black wire) that I prefer?

Eventually this fan will be on a small dolly that I can wheel around
and use in various situations. Hopefully, have an on / off switch.

Also I would use hardware cloth to keep my fingers safe :-\
