Just a helpful tip here if you haven't found a blower for your setup yet: The exact same 2" blower they sell on some pro sites for $300+ for hobby-sized evaporators (Half Pint, etc) is only about $65 on Amazon ("Dayton 1TDP3", 70cfm). I found there are also very similar priced/sized units on there that range from 40 to 150cfm. Amazon also has speed controls for some blowers for under $20 too.

2017: Found a new addiction/hobby!: 6 taps, Coleman stove/turkey fryer, graduated to barrel arch, 1.75 gal
2018: Increased efficiency - 22 taps on 3/16 gravity vac, 10 buckets, homemade extended barrel arch w/ firebrick, warming pan, 20X30 baffled pan, small home-built RO, 11.5 gal
2019: Same as above now with AUF, home-built float pan, gas sap pump, fewer fire brick but more insulation, maybe a few more taps if the wife lets me. ;-)
