I built this wooden brew stand a few weeks ago.
I made it out of 2x4's for the base and uprights and 2x6's for the top. I have the HLT and MT on 1/2 particle board and the burner on cement board. I don't need to heat water in the HLT because I have an on-demand water heater that puts out 175F water from a faucet in the garage.
The burner is a 32jet natural gas wok burner. I've capped half of them to reduce the amount of flame coming out from under the keggle during WOT.
I used aluminum flashing to protect the wood from burning. I've done a few test runs and so far no fires. I also cleaned up the look and tried to avoid cuts by putting metal duct tape on the flashing's sharp edges.
Since these pictures I've switched out the barb fittings for camlocks and installed two of the lightobject pumps.
Sadly I have not yet brewed with it. Right after I finished this I installed underground sprinkling and then had to travel out of town for work. Maybe in early September I'll get a chance.
