Hello all, been lurking for a while and thought it was time to post something. I've built a few smokers in the past most recently my go to has been a UDS that puts out some pretty good Q but just doesn't have the capacity I want. That brought me to searching for a tank to complete a RF smoker build on. I bought a large ethanol tank that I will be building into a trailer and the day after that I was given a 60 gallon air compressor tank for free so I thought I might as well build that one first and then scale it up for the trailer. I'll be plugging all the numbers into the calculator and basing the build off of that but here's what I did yesterday. Mounts cleaned off the tank Cut the top of the opening and made some hinges for it, they're a welded bullet style I placed .035 about the tank height for swing clearance. Just welded some round stock into a piece of tubing and sleeved the other side. Then cut the rest of the door and made a stop to keep it from swinging too far back. It allows the door to open just past 90 The door handle is just temporary so I'm not fiddling my digits in to open it every few minutes. This one I am thinking will be built with 1/4 plate for the FB and RF plate, and will just put it on 3 casters since it will mostly live on the patio. The weld and fab quality on this one isn't as nice as I will be doing on the big unit but it should get the job done. Here's a picture of the big tank. Supposedly 225 gallons, 66inches long once the stands are cut off and 34in in diameter. Base plates are 3/8 and the body is closer to 1/2. Just ordered the axle components I need to build that one but I'm thinking the FB will end up being either 1/4 insulated or just all built from 3/8 or 1/2 plate.
