My wife hired one to run 3 20 amp circuits out to my shop about 50 feet back in my back yard. 1 for dc, one for the tool in use, one for the LED lights and AC/Heater
Good idea. I have a blank space for a breaker, and the breaker box is right above where I will put the DC. Thanks.

DesertRatTom @bdbailey Almost forgot, Shop heating solutions. There was a long discussion on this recently. I have a similar problem during winter. Cold hands around spinning blades is a dangerous situation. Some solutions were using the gas outlet for a dryer to feed a closed flame heater. There are combination AC/heater units that are electric. But after all that, I realized that I had to insulate the ceiling and drywall it or any heat would simply be dissipated. The walls are already insulated, so since I'm too old to do that project, someone's coming in to do it with at least R38 batting.

That done and about R12 foam/bubble insulation in the roll up garage door--with good door seals--and I'll just run the gas dryer a few minutes and vent it into the garage. There is enough fresh air circulation from water heater venting so it will work and once heated enough, it will cool slowly. During summer (desert here), the insulation will mitigate the heat. Maybe AC some time in the future, but I'll see if it's needed. My shop has AC. Radiant space heaters near your work area is another help. Just no open flame or heater elements.

Hope this helps.

Plenty of air flow, no dust gets through. Picture below.
This is a subject that's on my mind a lot right now. I bought the RZ industries mask, and it works really well. But it filters so well that, with me having pretty severe COPD, it's an effort to inhale through the filter. I had been thinking about coming up with a fresh air mask, with a pipeline running to outdoors to plug into wherever I'm working, but those masks are really pricey.

I hadn't seen these powered units, and it seems like a good solution for the money. You're a veritable encyclopedia here lately, Tom. Thanks for the tip.

DesertRatTom @bdbailey Budget is always a problem and finding a balance between that and safety is tricky. A box fan and filter needs to be set near a wall so it creates a circulation. In a two car garage, I'd set up two fans on opposite walls, suspended from the ceiling With an attached garage, the problem will be tracking sawdust into the house, and having the fine, suspended particulates leak into the house.

Sawdust extraction at the tool is also very important. Sweeping up sawdust after you finish working is likely to only launch more fine particulates into the air. I spent a lot of money trying to put together a good home brew DC (Dust collection) setup, none of which really did the job. Finally, I got the Harbor Freight unit, on sale now and again, for $187 with a holiday weekend 25% off coupon and on sale. Still had to buy a couple of other parts and a 4 inch hose to attach to different tools. It cost me about half what I'd spent on various parts, blowers, barrels and such. I have two, one in my 12x24 shop that has a really fine additional drum type filter, and the other in my garage where I prep wood and resaw. The garage unit just has the cloth filter. The shop's canister filter lets me recirculate shop air rather than blow it out along with the heat and AC air.

A good DC system does not negate the need for a mask, eye and hearing protection. The DC units also serve to vacuum up the shop floor and shelves.

All that seems like overkill to some, but for a grand total of about $350, you can avoid a raft of breathing problems. I am a throat cancer survivor and the carcinogens in sawdust are NOT going into my throat and lungs! Discuss this with your spouse so she's on your side on budgeting for this. After taking me through radiation and chemo, my wife had no problem with my investing in good DC.

furboo A mask is a must. The only reason I also have air filtration is to help minimize dust getting into the rest of the house. If my shop was in a detached garage, I probably wouldn't bother with it.

Chris Hachet Mask and dust collection 100 percent. And I agree with Stick, I stopped using steel wool decades ago.

Job and Knock Wear a mask and get a vacuum cleaner attached to the tool you are using (which is far more effective than the air filter units which hang from the ceiling) and make sure that your vacuum has a fine dust (HEPA?) filter and that your mask fits properly because if it doesn't you'll just be breathing-in dust round the sides of it.

mlerchenmuller +1 on the 3M 6000 mask. Works for sawdust as well as fumes from finishing products. It is a half mask so it does not interfere with glasses or safety goggles. A very high level of particulate filtering. It's the very fine sawdust that will harm you. Most of the dust collectors are not very efficient removing the very fine particulates.
