Did some beer related work tonight. Finished sealing up the box with that aluminum duct tape. Also wrapped the beer and air lines with Reflectix.
Close up of the inside of the box.
I also received the new drip tray / glass rinser combo. This thing is a beast. It's still in the protective packaging, but you can see the glass rinser in the middle. That works perfectly for my situation since there are two studs smack in the middle of the tap box behind the wall. Almost looks like I planned this...
Custom countertop has been designed and will be fabricated soon. Once I get that in place, I can mount the drip tray, get the metal plate on the wall for the "tap back splash", install the shanks/taps/lines and pour beer!
