I've been viewing this site for months and just got to say you all corrupted me. Starting searching craigslist and found this 80 gallon compressor for a 100 buck they said the pump was sized no big deal just wanted the tank well I pick it up and end up selling the pump and the motor for 200 so I'm up 100 can't beat that. So the build is on. Just one problem regular flow with tuning or reverse flow? The Feldon calculator is great. Here is the progress so far started around the end of Feb. goal is to complete by end of April. Firebox is 20x20x20 and the FB Tto CC is right around 66sqin. Plan is for a slide out ash pan and the fire grate right above the intake holes which are 2.5" total of 6. I would like to thank everyone who has posted their builds alot of great builds to get ideas from.
