I've been working on a sketchup model of a single tier brew stand I've been itching to get started on. I'm looking for any feedback on anything that might not work well or could be done better.
I'm planning to use high temp painted 1.5" square mild steel tubing welded using wire feed or mig. The stand will be approx. 60" wide, 20" high (2' high to the surface the kegs will sit on if you include the 4" casters), and 17.5" deep. I tried to make it so that the keggle edges will rest roughly in the middle of the tubing. I'm intentionally making this lower than many designs I've seen on the forums - hopefully this will make it easier to see and clean inside the kegs without a stepstool. I'm planning to use 3 BG14 burners as pictured, a plate chiller I already have, and a march pump I already have.
I paid particular attention to several threads about heat shields and venting heat and exhaust gasses. I'm using a heat shield, which I might buy here: http://www.brewershardware.com/12-he...ner-mount.html
, or I could try to make out of some stainless sheet or duct or something.
I added gussets in the front of the stand to create a solid surface in front of the kegs. The burner shield is mounted flush with the surface, but I've cut out 1.5" of the top of the ring in the rear to allow heat to flow out that side and up around the corners behind the keg. Hopefully this would successfully keep heat away from the valves and silicone tubing in the front. I've seen some examples where they've opened the back of the heat shield and lowered the rear frame member to allow heat to escape out the entire back, but I felt like that would weaken the frame and this seemed like it would work just as well. It's a little hard to tell in the pic, but I was planning to use pieces of 1.5" bar stock to weld the heat shield/burner mounts into the frame. I was thinking I'd drill several sets of holes in the heat shield at different heights for the purposes of mounting the burners and this would provide some height adjustment on the burners.
Any feedback is welcome, but my main questions are:
1. Will the stand be strong enough as designed? What gauge tubing should I use?
2. What could I do to keep paint chipping and rust where the keggles sit on the frame from becoming a problem? (or is that not really a problem for others)
3. Is the approach taken to venting heat and exhaust gasses good?
