A little sawdust and a hot coal that escaped the stove undetected spell instant danger.

Unbeknownst to a lot of amateur craftspeople, even untreated wood can be replete with toxic chemicals that, when sawed or agitated, can irritate your eyes, kickstart an asthma attack, or make your skin itch. The easiest way to avoid those issues is to use tools that have a dust collection hook-up, usually an easy to connect spot for a shop vac or exhaust fan. But dedicated workshop warriors should consider stepping it up a notch with a whole-shop system that can be easily assembled with the right pipes, tubing, clamps, and patience.

Use a cyclone system to take things a step further and collect the tiny dust particles you might not be able to see. In a perfect world, your workshop will be detached from your home or cottage, but so few of us have the luxury of living in a perfect world. Why leave open space around fans, would not the fans pull better if the space around fans were closed up. Hi Paul. George, Appears that you may have room to hinge the unit to either door jam, this would eliminate the chance of the unit tipping over.

Can always pull the hinge pins to move the unit. I thought about creating a pivot point, but I also like the idea that I can roll it around the shop if I just want to create a breeze. Maybe a pivot with easily removable pins….. Nice economical idea but some sort of screening might also be advisable to keep out bugs and critters.

One way to eliminate the tipping from the front-heavy stand might be to move the plywood frame etc. If the thresh hold is to high for the castors, one set could be moved toward the center back set and the base could be tapered to actually cantilever the weight by the base extending over the thresh hold.

I think that would solve the problem. Excellent way to ventilate an entire shop in hot weather. The fans would work better if you close the gaps between them and between the frame and the floor. Air takes the path of least resistance, so some air is likely currently sucking in between them and going right back out without ventilating the shop. I wondered about the non explosion proof fans too.

Not sure how critical that might be in the way he is using this set up. A discussion about that seems warranted. I would benefit from knowing more. Simple fix would be a 3x8x16 solid concrete block on a the shelf of the bottom frame for ballast. I do this with my portable bench saw table saw set on a workmate base to keep it from tipping during use.

Works great. Would this system work better as a way of getting saw dust out of the air than a system that uses a filter?
