I seem to recall a conversation about how hard it is to put a Gray gizmo on the line - but it's all a blur. Got Part #'s? Also - why did you use the PVC cap to hold the heater element instead of the locknut from Bargain fittings?
Because Bargain Fittings was not known at the time 7-2008, a lot of the fist electric rigs out there were using CPVC and such.

I have used the BF nuts, but right now I prefer SS half couplers as they are more cost effective and provide a smaller dia. footprint (able to mount elements lower when doing a side install)

The LocLine is easy to assemble until you get to the threaded adapter, that is difficult. I boiled mine, used oven mits, and smashed them together, or you can buy the tool that McMaster sells.

Just picked up some 304 SS square tube today for $35 per 20' length... cutting and TIG welding that next week for another build...

I cant seem to locate a photo, and no longer own this rig... sorry. Ever seen the thermowells that they sell for fermenting? It is just like that, but without the airlock hole.

That's strange my first electric brewery assembled in 100% stainless I Tig welded my own dry well plugs back in January 1992 after I purchased my second Miller 350 Tig welder. I used those mechanical 1 1/2" dial pocket thermometers you thumped to move the needle 4 degrees.You were probably having your milk and gram crackers then your nap time in school back then.

What size square tube are you using? $35 sounds like a deal

Default Grounding\Wiring questions again

I am in the process of setting up The Pol's HERM system and I have a few questions regarding the grounding and wiring of everything. Not real knowledgeable in the electrical dept, so I was hoping someone could help me out. Both the Element and stir motor only have two wires\terminals and I know it is best to ground them.

How am I supposed to do this when there is no ground terminal?
Do I just screw the ground in with the common? If so, I was going to just wire the ground into a triple gang box and back to the pug and panel. This would be better than grounding to a metal plate, correct? ( I have a wood stand)

Pol, how did you mount your stir motor on the top of the cooler? I know there and threaded holes on the bottom, but I do not want to put holes all the way through the lid for this. What type of wire did you use to wire the stir motor up to your switches?

Thanks, Scott...

I have a friend in the business.

$35 per 20' is the cost of mild steel... $199 for 20' was the cost of SS before the "discount"

Peace....

My build is progressing slowly - mostly 'cause I keep adding to it. The latest thing that I want is a simple timed alarm - set it for 30 or 60 minutes (or whatever) to sound a LOUD alarm so that I remember to set the PID to the next temperature for the mash. Seems really simple - but I've been looking for a "cheap" alarm that's audible (excludes kitchen alarms) that works off 110 volts and mounts in the control panel with no luck. Even the timer on the Auber website is kinda high considering what I want to do. Is anyone else doing this and can point me in the right direction? I hate wearing watches - and the ones with an alarm are not really audible if I'm working in the shop.

Pol, I know this is much much later, but where exactly did you find a 12" false bottom with a 1/2" elbow barb? I can only find the 12" fb with 3/8" and I don't wanna run all around Chicago looking for a 1/2" fitting in SS that may not exist. Might be easier to return mine and buy a new fb with the right 1/2" fitting.

Fc36,

I am obviously not Pol, I think he has stopped using this forum over some drama with another one of his builds. Anyways I read in this post where he said that his elbow barb was 3/8" and he didn't think it would cause a problem. There is a possibility that he changed it later but I have not ever read that he did for sure. I see you quoted him saying his was 1/2", is he referring to his false bottom barb?

Anyways I have a nearly identical MLT and I use a 3/8 SS barb. I really have no way of knowing if would get more flow out of a 1/2" (everything else in my setup is 1/2") but I can say that it doesn't bottleneck my system. Mcmaster Carr has 1/2inch barb to 1/2" NPT elbow's but I think they are crazy expensive. Maybe try bargainfittings, if you must have it 1/2" you could use a 1/2" street elbow and a normal barb.
