That's foamy AF! Build thread?

Ummmm.....WTF? Need more input.....

No build pics... just threw it together out of a harbor freight sand blaster that never really worked right. I rearranged the fittings so it siphons the water/soap mixture out of the bottom of the tank. I can adjust the ball valves to adjust air pressure and water flow to fine tune the foam. (I can also adjust the pressure in the tank)

Inside the pvc pipe I stuffed some scraps of cedar breather I had laying around. I plan to pick up some steel wool to try as well. Going to also adjust the size of the outlet on the pipe to see if that makes a difference... Ran out of time for now but it works quite well as is. The foam was coming out a shaving cream texture.

Middle of a pandemic seems like a weird time to get into foam parties but you’re off to a good start!

Pot scrubbers would work but I’m not sure they’d be any better then what I have. Going to try stainless steel wool under the assumption the tighter the packing the better the foam.

If I use the foam as a Lysol dispersant maybe I could exceed the six person thanksgiving gathering limit?

Picked up some synthetic steel wool. Seems to be working better.
