I have a very small shop...and I mean SMALL!
My DC is my shop vac attached to a Thein modded 5gal bucket. The Modded bucket works VERY well, as it is intended to. However the daggone thing won't stay upright on the floor. The hoses continually knock it over.
My next issue is with small paerticles of dust being blown around by my box fan. I read that someone here taped a furnace filter to the back of the fan and it solved the problem.
I did this and after cutting some MDF (nasty stuff) the filter completely clogged up so there wasn't any air flow.
My fix for both problems this weekend:
I thought that if I taped an old T-shirt to the back of the fan, that it would not only collect dust but I could wash the shirt when dirty. I tried it yesterday and sure enough it has collected a decent amount of dust.
Next, the 5 gallon bucket. I thought about making some sort of wheeled carraige...or maybe something heavy. I found in the dim dark recesses of my shop a couple of 5lb weights (barbell type) I put two into the bucket and presto, no more falling over.
Just my .02 today.
