I do not understand how a 2/3 hp motor can out perform a 2 or 3hp motor
on a big dust collector.

He's confusing static pressure (vacuum) with volume. It is not a
vacuum pump but a air mover.

This guy is really cool. He's got way too much time on his hands, and he
has way too much patience, but he comes up with some really cool stuff.

What a cool project to work on.
Yes, he is quite a patient model builder....
I envy his carefulness......
I was wondering what it would be like to either cast in aluminum, or build
with sheet metal......

He retired. He worked for Blackberry (RIM), was an engineer there.
Probably an original .... He realized the company was going the wrong
way, like so many who think they are on top and can't be touched.

Obviously Blackberry (RIM) thought the smart phone could not touch them.
They didn't cover the bases.

Not sure I understand, he has a blower that is pushing a large
impeller... something that a 2hp motor would be required for. His is 2/3

Both his DC and this blower are on, and he is overcoming the more
powerful DC... which he should not be able to.

So it is more powerful.

Still, I loved my Crackberry...

His home made impeller is certainly more efficient that the 4 or 5 blade
one in the larger unit so it probably spins with less effort.


Having said that, the smaller unit simply relieved the pressure inside
the filter bag, naturally the bag would collapse. Had the smaller one
really out performed the big one I suspect that the bag would have
totally collapsed immediately rather than gradually float down.
Since the bag did not actually flatten the larger blower still out
performed the smaller one. And depending on the layer of dust in the
upper bag, the less the restriction, the more the smaller unit would
appear to be out performing the larger one.
