I worked out of a two car garage at the time I made this so wanted a large Cyclone but not needing one of those high buck systems. plus I just kept seeing the shop made out fits and wanted the challenge.
I made it using a 7 gal. pool bucket so it holds quite a bit a saw dust before it needs emptying.
These pool buckets also have a screw on top and are made with extra thick plastic so I've had no problems with it collapsing on me.
I boxed in the vac so it is much quieter but be sure to leave a lot a space for cooling or the vac can over heat.
Over at LJ,s I had a blog on the build so if interested you might what to check it out.
