Great mini build, in particular the mod for the removable thermometer. That's awesome. What size face bushing did you use and can you recall where you purchased it? I'm attempting to fabricate something similar. In my initial attempt, I used a stainless steel 1/2" to 3/4" NPT hex bushing with a 1/2" SS lock nut. I tested it out using a piece of cardboard to mimic the tamale pan and realized that the tapered threads of the Tel Tru prohibit the thermometer from being fully screwed into the bushing, thus leaving a a bit of a gap where I'd prefer it to be flush. I assume this would work, but it would just look better (and the stem would be farther into the smoker) if the thermometer could be flush with the bushing or washer when inserted.
If you needed a 1 and 1/8" step bit, I would imagine this would be for a 1" bushing but I couldn't find any 1" x 1/2" NPT face bushings. Was yours a barstock face bushing? Also, of the brass face bushings I've come across, some are lead-free which I'd prefer but they have a max temp pf 250 deg F, which is where I'd probably around where I'd run the mini, but that seems a bit low for a smoker so I'm curious how it holds up. I know brass ball valves are used often in UDS builds so I suspect the brass, while I prefer SS, will be fine. I can get steel or black iron bushings from McMaster Carr, but those would rust. In any case, if you could share a link to or share the source you used for the bushing, I'd be grateful.
I don't mind if I need to pay a few more bucks to get the right bushing, since I already have a UDS and modded ECB so the mini will be the last one I build for a while and if the mod works, I might use it on my UDS. Thanks in advance for the help.
