I have a decent dust collector with 4” pipes but it is pretty inconvenient for small tools, particularly sanding. I wanted a mobile solution that I could wheel up to where ever I was working. Using a shop vac by itself is a poor choice because I wanted a HEPA filter for the really fine dust that sanding generates. It would clog up pretty quickly. So, some sort of separator was needed. I’ve seen several designs like Jay Bates’ that use a dust deputy. I felt that wouldn’t work well for me because the DD is so tall that I felt the whole thing would be unstable. So, I got a “cyclone” separator on sale from Woodcraft (reviewed here) and a small shop vac. I added a Thein Baffle to the separator and it seems to work pretty well. I was concerned about the small shop vac being underpowered but it turns out to be more than enough. I added an iVAC switch box (reviewed here). So, the vac will come on when I start the sander (or what ever) and it will run about 4 seconds after I turn it off. While I really dislike the iVAC company for their misleading product claims, this works well for me.

One of the keys is that I didn’t want a lot of extra tubing that a dust deputy would require, so I elevated the shop vac just enough to allow the gooseneck from the separator to the vac to be really short. I think it works really well. I added handles at about 36” high and that makes it super easy to move about. I pulled the castors off the shop vac and mounted them on the bottom of the cart.

I’m pleased to say that this is working really well. The HEPA filter gets what little the separator lets through, the cart is really easy to use and the iVAC switch means that I don’t have to start the vac separately.

I’ll probably add something to hang the vacuum hose on in the future though it stays put when wrapped about the unit.
