I will be welding mild steel and rebar primarily w/ a FCAW in my garage. I have a up to 3500 CFM floor fan I plan to put next to my table pulling away from my table and out the front of the garage. I read that flux core wire does okay with a breeze. I will also open a door at the back of my garage for air flow. I have a half face respirator with 2097 filters. This seems solid for PPE in my case and ventilation for hobby welding from reading in this sub reddit. I also read some folks dont run respirators as their ventilation carries it away?

I have some hardware I'd like to incorporate into a windmill for a friend. This old hardware belonged to his late dad. I would like to weld this project together and have it spin on a bearing for ease of movement.

I am curious which sealed bearing type/material would stand up to rain over time and not rust? As a noob, this feels like it may be a tall order but figured I would ask here as others may have a solution for this?

Appreciate any guidance.

I purchased this table and the top CNC machining with no factory post work leaves the holes and edges of this surface sharp. I cut my hand taking it outta the box.

Wiped down the top thoroughly with paper towels to get the storage/shipment oil off it.

Used a stepped bit for about 2-3 seconds per hole with some medium pressure(just a bit more than the weight of the drill provides) to clean out the hole edge. Sanded the whole surface with a few pieces of 220 then to get any metal bits sticking up from the drilling and also sanded the side edges, top and bottom, and now I can run my hand across the top and edges without getting sliced. Gotta protect your money makers.

Do the fiberglass blankets break up the welding flash enough to protect folk's vision on the outside from damage from welding flash?

I picked up a flux welder to do some small project in my garage. I have good open space out there and a solid fan to move air through. I feel I am protected with the gloves, helmet, etc I have. However I want to protect my family and anyone walking by, if the garage is open enough, from the welding flash. Do these blankets work well enough to break up the light flashes so they are not harmful to them?

Thanks in advance.

I have a window AC( Frigidaire 6,000 BTU Model FHWC064TE1 ) I installed today in an upstairs bedroom and the compressor noise really carries in my backyard(and for my neighbors) which is otherwise really quiet. I am curious what I can do to quiet this noise? Anyone ever put up panels to the side of the AC unit (offset 10") to help contain / deflect the noise?

Also curious if any of the window ACs out there for a ~180sq ft room would have a more quiet pump? Do the dual inverter units have a more quiet pump system?
