This Page is about my home made dust collector.
I made this in the summer of 2005 and it works pretty well. It could use a little more
pressure, but it flows a good volume of air and filters quite well. I build the collector from
salvaged materials. I spent a little on some switches and filters. In total I spent under $20
to make this, not including piping.

Front view - the unit is 41" high, 38" wide, 16" deep, and was sized to fit between my
workbench and lathe bench. The wood is a mixture of particle board, chip board and
plywood, all scrap I had lying around.

The squirrel cage fan came from an old
furnace that I salvaged when I helped
renovate our old church office. Pulled the
fan before the furnace was dumped into
the bin. The fan has four speeds hence
the on/off switch and three two-pole speed
control switches.

The collector is a four stage unit, The first two
stages dump the air into large chambers so
the larger chips fall out. Below you can see
the clean-out door open to show the bottom
of the first two stages. Notice the larger chips
in the first stage on the right.

The third stage is a dust bag- created
from a cotton t-shirt. The old boot laces
keep it in place. This works well. The
dust falls back down into the second
stage below.

The fourth stage is a series of furnace filters. I
was expecting these to clog badly, but I have not
had to change them yet. The bag is working well
and I am not getting fine dust in the outlet as I
was worried about.

Here you can see the side outlet and the 3" ABS
drain pipping and 4" dryer tube used for the main
piping. The flex pipe goes to the lathe - see
below-left. Anyone interested in more detail see
the sketches below-right.

Dryer flex pipe and a blast gate are used to
collect the dust off the lathe. I have also
plumbed in piping to the sander, drill press,
bandsaw, and table saw. I also added a
floor sweep near the lathe.
