On to the Burner heat shields. I went with two because one did not protect enough. I want the exhaust gases to vent to the rear. This is not completely done but this is what I have so far. Notice the Shields go up above the deck level. thats because they fit tightly to the inside edge of the Keg bottom.. No heat can escape up those sides.. The exhaust heat is directed to the back and up. / next step is to fabricate an exhaust chute on each side.

Bottom pic you can see the termination / connector to the RTD probe hanging. all wired inside the frame and color coded heat shrink tube. (Red = BK, Yellow = Mash and Green = HLT)

I ran every single wire inside the frame of the Stand. Here's the RTD Thermo connectors comming up through the front frame.. They are made using Kal's method www.theelectricbrewery.com/temperature-probes
As you can see here though I additionally covered them in a third layer. Its a product called Insultherm.. http://www.ebay.com/sch/i.html?_nkw=INSULTHERM+1200+deg.F&_sacat=0&_odkw=I NSULTHERM+1200+deg.F+10+feet&_osacat=0&_trksid=p32 86.c0.m270.l1313

It can handle up to 1200F. first pic is with the Insultherm on the cable. the second pic is befor I put it on.

CLEVER! Nice work.

Fingers crossed there are no issues with the wires inside the insulation layer getting overheated - but I love the build! Lots of great features being implemented.

I put the wires only in the front and front down posts. no where near anything that heats up. (since I have it designed to exhaust the heat to the rear) I tested this first.. I also mounted the heat shrouds with a fibrous fire resistant washer to reduce transfer of heat to the stand.

Great job so far.
Seems like you invest a lot of background work too.

Very nice build! I'm interested to see what you come up with for venting the gas buildup underneath the kegs. I'm having the same issue with my stand and can't figure out a way around it. My flame is very weak because of this... I was concidering using a plasma cutter to cut slots in the bottom of the keg skirt, but wasn't sure how that would effect the overall heating times...

I tested the idea of the two shrouds around the burner. I got great results in the front.. the rail heated up to only 100f . Which was really just warm to the touch not hot.. So Im pretty confident the wiring is gonna be fine.. But the back rail was so hot, it smoked the paint right off. I knew that was gonna happen but I wanted to see how much. So Im adding more heat shield from about 9pm to 12 noon on the clock face..So that only that one corner is left open and I can build my heat (exhaust) guide up an out from there. I also noticed that I may have to add some forced air into these burners.. Just too much yellow flame...I put a computer fan near the opening and forced air in and the flame was beautiful.. So Im gonna work that idea too
