Here's a dust collection device built from scratch.
SHOP OWNER: Dave Sloane
LOCATION: Edmondton, Alberta, CANADA
This unit is my second project; the first was built from plans in WOOD Magazine. I use a 64" x 20", 1-micron filter bag; and, even though most people are jumping over to canister-type filters, I believe that this system is more than adequate for my purposes.
I used commercial metal barrels for the cyclone drum and dust catcher. I incorporated a ramp and neutral vane to try and stop airflow turbulence inside the drum. The neutral vane is circled in red and basically it is just the inlet pipe extended right up to the exit pipe.
The impeller is made of structural aluminum and mounted onto a 2-hp, 3450-rpm motor. I machined all the aluminum parts with carbide woodworking tools. It took a fair amount of planning and improvising to get it balanced and true. Actually the balance came out near perfect after I devised a way to true the wheel.
