TIG time boys and girls! Xmas came early. I realized there was no way around learning tig for this project, so I bought a new DC machine after reading up on what to get and watching a lot of youtube. (George doesn't care). All plumed in and ready to cook.Got a CK 9 bendy head torch and ordered...

Ok so the frame was coming along (we are into November 2018 now), and I was waiting for a new chop saw. Switched gears a bit to the kegs. I chose kegs as starting material bc they are SS, cheap, easy to get, designed to hold pressure, and already have a curved bottom which will be needed for...

Sealing up those purge holes i had to drill! Time for the top, where the vessels will sit on. Fit up test.SS 304 is EXTREMELY hard on tooling. I would maybe get 15-20 cuts out of a blade before sharpening. I bought a new Dewalt ($150) specifically for stainless and boy was it a POS. 3 cuts in...

Got a nice press off CL with stand for 100 bucks. Drills straight and will use it for drilling the kegs.Upgraded my chop saw to a professional Trajan saw. I wish i did this from day 1. Would have saved me so much heartache and probably 2 weeks. Tacking on the legs. Once the rest of it was...

Getting reasonably proficient with joints.Some test fit-up. Top of the frame is cut and ready to be tacked. Close up of a corner. Good fit-up is important and was very hard because this saw I had was junk. Wouldn't make 45 cuts properly without a lot of messing with it. Welded joint. I don't...

Sept 2018 -Bought a Lincoln weld-pack 155 flux core welder. Nice older machine I got off CL from a guy who owned a fab shop. He took good care of it and it's internals were in nice shape. It needed modding to run MIG shielding gas. New helmet. M'URICA! Didn't have 220 if the garage. So...

I got into this lodo build project late last year. I was already thinking of building a more serious manually operated system, when I saw what Die_Beerery (shout-out) and some others had impressively accomplished. I hadn’t previously realized just how seriously brewing could be automated and...

super cool. Does it keep the port sealed in between additions?

Hey, As always pretty cool stuff. So even though you are doing everything under n2, at the end you oxygenate your cold wort?

No need to reinvent the wheel!

I ordered them to specification in china using alibaba. Specifically, Company: Shaanxi Qijia Automation Technology Co.,Ltd. The specs are: Model: CAP-WS Pressure Sensor Accuracy 0.2% Pressure Type: Gauge (G) Range:0-20kPa Temperature Range:-40-150 degree C Output:4-20mA Power:24V Connection...

Hi All, I'll start a new thread this thanksgiving break been busy welding the frame together out of SS all weekend. More parts arrived like my Hoffman box i'll also update.

MM Mass Flow DS100HBetter condition then expected one was a bit dirty but should clean up nice. Bigger then I expected. 10" welded tri clamp fittings ordered from china for the 3 kettles (x3). drilling and welding several 1.5 inch tri-clover fittings into each.pressure sensor spec'd from...

Cool I bought the correct ones then. Wasn't sure if you could loop in-line with the HIM into the 24mA out of the 9712 and use 2ao (cheaper) from the HIM and 1 from the 9712 for the arduino, or if the 9712 needed a dedicated line to the HIM. This is simpler though. My 9712s, DS100s, HIMs, and...

Another question...are your HIM Hart loops each 2 analog out or 3 analog out?

Ah that makes sense. So you open one of the ports and toss some in once your at 212 I assume. Cool. Do you re-purge the kettle with n2 during chilling?

How are you currently doing hop additions? if the system is purged and sealed, how are you adding hops at desired time-points?
