I don't have any more pics of the chamber/stand. I did use 2x4 to frame and then 3/8 inch (or something close) plywood on the inside. I caulked every joint on the inside. I built everything but the top and then lined with 2 layers of 3/4 inch insulation. I staggered my joints with the insulation and used a little spray foam to fill in any gaps. I used an adhesive spray to get the insulation to stick on the plywood. I put my "ebay temp controller" in and directly wire a fan to the controller to always move air around. I put the top 2 layers of insulation board on and sprayfoamed the top against the playwood, then I put the top of the stand on. I foiled taped all the joints on the inside. I have the door opening staggered and used weather stripping to seal the door. I got in there and closed the door and found no signs of light, so I think its pretty air tight. There is probably about a 3 inch gap between the top of the insulation and the top of the stand. I actually have my controller power cable, the compressor power cable, and the ebay controller power cable routed in there and have everything coming out the top middle of my stand. I don't have the dimensions on me (I'm at work), but I wanted to be able to fit a sanke keg inside (initially wanted to get the sanke fermenter kit). Theres not much more room width wise, but I can get one in there. I think I went with about 5 feet length, to fit 3 kegs on top. Height was also to fit a sanke keg. Its pretty tall once the castors were on and the top of the stand, so I plan to make some kind of running board/stool to be able to peak into my keggles. I don't plan on heating, but it's been pretty cold (38 degrees) the last few days...I haven't fermented in it yet, but I should have a 6 gallon carboy with my pilot batch in it by Saturday.
 
I had my pilot brew yesterday. Couldn't post about it until now due to my other hobby taking up most of my day...

It was like a small victory seeing the wort circulate through the hoses since this was my first all grain effort, and second time overall

And seeing the mash

Underestimated my boil off rate, so I only got between 4 and 4.5 gallons. Hopefully I'll get that fixed for next weekend brew. I think my efficiency was about 84%. I pitched the yeast at 4 in the afternoon. Started seeing a little activity by 11. This was this morning at 7

My second all grain batch with my first liquid yeast starter. About 30 hours after pitching the yeast.
 
Good write up. I was there for the first several brew days...the end result was fantastic. I will eventually be making a similar set up here in MD.
