Project Information

This has GOT to be one of the most useful additions to my shop ever!

Found the plans on WoodCraft's website ( http://www.woodcraft.com/Articles/Articles.aspx?articleid=408 ) for this easy-to-build dust pre-separator and it screamed out "BUILD ME"!

One of the reasons it screamed so loudly is that I had just picked up the exact same trash can at a flea market the weekend before for five bucks - all it had wrong with it was a small hold in the top center of the lid which I needed to drill out anyway - how convenient!

This project took less than $20.00 worth of stuff from Lowe's and the Can itself plus 30 minutes of my time.

I modified their plans just a little to force the chips to more easily spiral down the side of the can and I also shortened the 10" of center pipe they called for. I also added a ring of self-stick weather stripping around the top of the can.

This is a HUGE improvement on my dust collector - not only does the bags stay totally empty, but the suction has far improved and stays that way the entire time until most of the trash can is full of chips. Plus it's WAY easier to empty. WIN. Win. win. ;-)

I tried something like that at one point, but it just reduced the suction. Your experience sounds great. Maybe I'll try again. Any good hints.

Kate,

The only hints I can give you is make sure everything is as air-tight as possible. I used a LOT of silicone both inside and outside around the pipe inserts. Also when you seat the fittings, press them really tight against the can and each other.

I'm not sure, but I think the weather stripping helps as well - I DO know if I block in hose completely when it's on, the lid depresses about two inches so it's pretty sealed. ;-)

Good luck!

I had to go back and buy a metal can for mine because the plastic one kept collapsing : ( I also made my own lid. : )

I will need something for dust control when I finish setting up my shop. I'm moving it to the upstairs of my garage where there is less windows and no door for ventilation.Thanks for the tips and pics., and link. I was wondering how well these work so it's good to hear your experience.

Pat,

I absolutely still use this but I DID add the baffle to it. I'll have to find pics, etc…. to update this post with. The baffle makes a HUGE improvement.
