Thanks man, huuuge burden off my back getting that evap issue resolved.

I used a few different youtube videos as a resource when I made my smoke machine. I initially started very basic using a paint can & incense which worked fine but then made things a little more "high tech" for convenience.

Very general parts list:
1 gallon paint can

assortment of 1/4 air compressor accessories from harbor freight: couplers, quick connect fittings, etc

1/4" Coupler x 1/8" NPT Male Thread (2) if using the dwyer flowmeter

dwyer flowmeter

3/8 clear tubing ~10'

24 gauge resistance wire that I got from a local vapor/tobacco shop

2 insulator binding posts

mineral oil (to increase smoke production)

propane gas regulator 0-10psi

oil lamp wicks

insulated alligator clips

Air source: having an air compressor is a nice luxury but I was able to make a bicycle tire pump work in a pinch when I had air compressor issues.
