Well, I've done a lot more purchasing lately, and have much on the way to me.
I settled on going ahead with the sub panel, and have the subpanel and all necessary breakers and the 50 amp GFCI for the main panel, along with the 6/3 wire.
I bought all the copper I think I'll need, plus some extra fittings just in case. I also bought lead free solder, flux paste, and brushes. I already have a propane torch which should be fine for the job. I still need to get the sink valves, and the stainless 1/2 valves are on their way from china. Haha. I am going to have three valves, one for the water filter, one with a camlock for flushing lines, and one with a garden hose fitting for other cleaning and flushing through the chiller. I do have converter adapters I've made, but I think it will be easier to just have the dedicated separate valve, rather than switching things around. I haven't ordered the sink yet due to its size though, as I still need that space for other things right now as I am working on some home projects at the same time too.
I also got the 30 amp 10 gauge cable, and it is hefty. I also just put in an order for PG21 cord grips (the 10 gauge cable is just over 16 mm in diameter), which I think will fit in 3/4'' knockouts which will be convenient. I also have the 30 amp switches and the AC whips, though with the 10 gauge cable, I may return the AC whips, but we'll see.
I'll be putting in the order for the two monitor arms soon.
I measured out dimensions for the mill to be mounted on hinges above the mash tun, and it should work quite well, hopefully.
I am still figuring out placement along the wall for all the electrical boxes for everything - vent fan, mill, chugger pump, sump pump, and a spare one for a future chugger pump if I want to fly sparge.
Once I figure out the placement for all the electrical, I'll go ahead and do the wiring, and then the vent hood, and then I can work on modifying the kettles and getting the conversion kits and controllers. I do already have the SSR for the HLT, but the temperature controllers are on their way from china as well. It was surprisingly difficult to find a 240v temperature controller that showed temperature in Fahrenheit. I still haven't fully decided on how to add fans into the controllers yet, but I'm not too worried about it.
I think I want to try silver soldering the brewhardware radius 2" triclovers. If I fail miserably with that, I'll just get the weldless kits from stilldragon.
I've moved things around in the garage, and put in an overhead airhose reel, which gives me more space on the ground.
I also still need to get the discharge hose. I tend to think I'll just get a rubber hose, as it should be able to withstand the higher temperatures the best.
So, some progress made, but a lot of work still left to do.
