Yep, ground is there so your house does not become a battery...

Anything with the accuracy to read an RTD (thousandths of ohms per degree accuracy) is going to be pricey, you can use this from AUBER: https://www.auberins.com/index.php?main_page=product_info&cPath=17&products_id=289 Or this cheap PID and just use it as a display...

The contactor is a mechanical isolation of both L1 AND L2 from the element. The SSR is using a pulse width signal from the controller to effectively transition the element from 110V to 240V at a rate that the controller decides by switching only one leg, L1 or L2. I much prefer the SSR after...

I picked up a partially completed 1/2 BBL eHERMS setup with 25gal pots. Looking for deals to finish it. I need: 2x pumps Counterflow Chiller QDs/Camloks/Hose Electrical control components (not interested in complete panel unless its cheap)

Well, naysayers aside I guess I wasn't arguing that there isn't a tool that exists that can make this work. Every one of these solutions requires additional pieces, parts and attention to make sure you get the hole ID to line up with the fitting The solution I have is dumb, it requires almost...

one more post and then I'll enjoy a homebrew. Also, for the average Joe looking to put 1/2" couplers in a keg this may not be simple enough to warrant $60, but if you have priced out the fittings needed to make 1.5" and 2" flares for other fittings (element etc.) those can start to get upwards...

and the female die is much more complex to machine...

Alien: Those tools are designed to be pressed into tubing to flare them, like exhaust pipe. They dont work for tank walls. Bobby: I agree, and I can make the females but I am pretty certain that since you are only expanding 1/16" of material that the socket you pull it into does not need to...

The concentric reducer we use in the typical keg tool has an OD of 1.05", which you don't want to pull all the way through. I was also thinking that you could just not pull this tool all the way to the shoulder for a coupler. However for clover fittings etc. an even 1", 1.5" and 2" is just...

Gee Vlad, thanks for the kindness, have you ever actually used a swaging tool on a tank wall, you did realize I sad tank and not tubing right? Did you look at the picture I posted or did you just get the idea to bash me in your thick skull and start rambling? Stop trolling. And FYI, since...

I decided to put my big ole' engineering brain to work and come up with a fancy tool to replace all the cobbled together fittings that I use to flare tanks for silver solder. I have; what I believe to be, an AWESOME tool design that I would like to get made. 304L stainless, of course. The...
