Ok, Thanks Bill, that was the essential piece that I was overlooking.

Is that why SuperFlow says 25" is typical ?

I was going to say something about the definition of "practical" but you
beat me to it. Almost anything can be done with the proper application of

use that spare Triumph motor in the corner to turn your blower ...
Thanks again to all,
