Both good ideas, still have to hit up the store tomorrow for the wiring so I'll look at those options, thanks! Also just remembered I need to dig up an old CPU heatsink for the ssr and figure out if mounting it inside will keep everything cool enough.

I'm scared to cut into this box

Yeah. Hard to make the first incision.

Plan. Plan. Plan.

Don't cut until you are damn sure you know where everything will go.

Yep, I plan on it. See below, that's not what I'll be cutting from but that's my basic layout I think. And a few more pictures of what I'm working with for reference.

So I'm back from Home Depot with I think everything I need to get this guy built today.

Question. How should I be mounting thins like the SSR and the terminal buses. Screw head outside and then shaft up? Otherwise I'll just have crap sticking out the back of my box no?

Got a great deal on a medium duty 14 gauge extension cord. 50' for $20... Should be enough for everything, RIMS tube will be rather close to the box anyway.

A good source for recessed male 120v connectors is a scrap computer power supply. I'm sure that you can get one from a local computer shop and salvage the connector.

Ah, well I think I'm just going to hardwire it in at this point.

I've got a heatsink but I have no clue how to mount it and whether or not it will get too hot inside the box if I don't mount it outside...

I could cut a hole and kind of glue it in but I'd rather it be inside.

So, I got some work done today, not nearly as much as I imagined but I figured almost everything out. Except: how do I mount this heatsink? Here is the layout I decided on, need a few more screws and a drill bit for the switches and then I can play with it again. I'm thinking glue for the heatsink, and of course drilling holes in it to mount the SSR on it.

Here is a setup I made similar to yours...
I have a separate box for the PID & RTD connection and the Power distribution.
I did it that way so I can use the smaller box as a digital thermometer.

I was willing to risk burning up a SSR to see if this would work. I used it a few times, but quickly progressed to a BCS controlled system.

I put a thermometer in the box and sealed it as best I could. Under 50% duty cycle running a 1680watt heatgun and a pump for 3 hours, the temp never exceeded 100f which is 37.8c. The operating range of the auber ssr is up to 70c.

There are NO fuses or over current protection in this build and the wiring is a rats nest.

I had no problems with it in probably 6-8 brews that it was used in. I still use the "Digital Thermometer" portion on occasion.

Portable power supply for the RIM's heater... Just kidding.

It drives a small buzzer through the PIDs alarm circuit.
