Cyclone Dust Collection

[Overs Pianos]

Terry,

Here's the post again with the impeller wheel image included.

Dean's suggestion is a good one.

A plywood box will reject enough heat to prevent the motor from 
overheating. The whole box will heat up a bit but the motor will 
survive. Don't forget that you'll have over 1000 CFM of relatively 
cool air going through the cyclone unit. As the box heats up some of 
the heat will reject from the box back into the air being cleaned 
within the cyclone.

Exactly, and your garage will keep rain off the plywood box, so you 
won't have to worry about building it from marine grade ply. But you 
will need to build an access door for emptying the collection drum.

Just had a look at Ed Morgano's site. He's using a backward curved 
impeller wheel. He's doing some very good work. The Jet range of 
dust extractors have similar good-design impellers, but they don't 
have a cyclone upstream to the collection filter.

That Mini Cyclone that Ed builds for shop vacs is a most excellent 
idea. I've been considering the same idea, but here's a man who's 
already done it. Buying a unit is far easier than building one.

I've already sent an enquiry. Thanks for the lead Terry.

Best,
Ron O.
