After sanding today, I have dust everywhere. I wore a mask, but I still feel like I inhaled a lot of dust. From now on I’m taking the sanding outside, but I’m also going to build me a dust collection system. The main culprit is the miter saw and that’s not to hard to collect, next is the router, then the TS.
I plan on using a washer motor I have new in a box. I’m going to mount this to a pulley system and gear it up to run at 8000 rpm to a massive squirrel cage impeller enclosed in a box which will vent outdoors via a 10 inch pipe.
The collection system will require that my shop is up and running and everything has to stay put, so it may be a while before I get the feng shui to a desired point.
The collection pipe will be 6” diameter run from the ceiling to each tool station where it will curve to the back of the tool in an out of the way spot where three 4” flex tubes can be used for each tool. One on the dust collection port, one to suck the surface and another to grab the dust around the operator, between the operator and the source of the dust.
I don’t know the math but it should move a ton of air. I don’t worry about the amp draw on the motor because using the proper diameter of hose with curved pipe will minimize the restrictions to the flow.
I have two garage doors that will remain open while working too. The pipe will just go out the door on the floor and around the corner so wind won’t bring the dust back in. It will be colder in winter, but I’ll use radiant heat to solve that problem.
