HI, I just posted about my drum&disk sander I made and now about my homemade squirrel cage dust syatom I made.
I got a smaller blower out a furnace [traded for it] and had some bigger down spout from commerical building was in dumpster too, I have read that these have no suction? Heck I built this put a board on it turned it on and could NOT pull it off, WOW it has suction. As you can see I mounted it above my wood lathe and ran down spout to my sanders and a 4inch duct to my lathe, I ran a 8inch to the outside, I dont want to collect the dust just get it out of the garage, [I may get a Y and two flappers so can run on low with filter for light dust and keep heat in shop will work good also] So I have 4 outlets that are 4inch and run the blower on high [it has 4 speeds I wired it for] and I cover the blower inlet with a board for this and when running the drum sander it gets All the dust, I cant believe how good it works. When I am spray painting I open the side up [take board off] and put a grill and fiberglass on it [I make filters from dumpster fiberglass I got] for a filter it works great for this too, collects all spray paint, my garage is only 24×24 but it works great. I open the little cat door for when I am using it to run drum sander and when painting I open small window on other side garage to get makeup air, if dont sucks my wood stove smoke back in.l

It has low, low med,high med. and high for speeds and runs on 110, Hope this can help someone and can answer any thing you may want to know, Thanks

Alright Bud2, you’ve gone and done it now. I have plenty of things going on for the next couple of months, now you come along and post this terrific idea. I won’t be able to get this off my mind for quite a while. I have a small blower from Harbor Freight but it really isn’t powerful enough. My father has an old furnace blower in his barn, he wouldn’t still have it if it was no good, so I have access to a blower. Now I just need the time and if you don’t mind I will steal your idea for my shop. This is another case of ‘why didn’t I think of that?’. I believe I have a new project now for the spring. Thanks for sharing this great idea.

hi farmerdude, I know what you mean, I think I am done with things then I see something that wow, I can use and do that. This really does work better that I thought from all the other sights I read about them people seem to say there not worth it, Like I did say I think I may add a Y on the 8inch outlet with two shut offs for each so I could run blower say on low and circulate the air in shop with a filter on it, just would help keep heat in, not sure yet if I do it?

I have spray painted with it on and wow the filter [home made fiberglass] turned out to be the color I was painting, Just keep asking myself WHY I did not do this long time ago? Just got sick of all dust I guess.
I did add a screen outside keep bats and birds out of it.

I just wanted it for all the dust and paint anyways, the saw dust from table saw and shavings from wood lathe dont bother me, they just land on floor stay there,I use them for starting fires in winter anyways.

Have your say...
