This morning I drilled/tapped the heatsink and attached the tube with a piece of wood. I will go pump then HEX although it would have made routing cleaner the other way round.
Next is mounting the PID, SSR, switches, and wiring it up.
Should I be concerned about the PID being in the same box as the pump? (HEAT, the liquid is all outside of the box)

Lots of progress today. Power cord with strain relief, switches with covers, SSR and PID holes cut and fitted, and some wiring.
I have 4 questions:
1) The RTD has 3 leads, 2 red one blue, which go where?
2) Can I just combine all my white leads with a twist connector or do I need to use a wire block like I did the grounds, and if I do so, is screwing it into plastic and wood adequate insulation?
3)Does the PID "need" a 1Amp fuse?
4) Will the pump create RF that would be an issue for the PID and or RTD leads?

Also please take a look at my rat's nest. I have a heavy duty power cord coming in, with the ground wire going to the ground block, the black wire going to the common on the double switch, and the white will be connected to all other whites (neutral, right?)

Update: I figured out the RTD wiring, and entered 21 (for my unit) for the probe type.
I found an offset of about 3˚ from my new CDN proaccurate thermometer, so entering thet in, it would appear that I'm on target. Freddy said to set the max output to 80% but I had no problems with boiling using 100%, but i only had the water up to 140 or so for my test. It seemed that I was able to make a 20˚ rise in temp with reasonable flow rates. I may do another test with a smaller volume of water that's already 155˚.
Just one small leak to fix and I do think I'll be putting in a small exhaust fan. The pump gets the box fairly warm over an hour, or maybe I can just crack the lid open once my fluid connections are good. Hoorah!
BTW that heatsink is severe overkill (for the load), it barely got warm, and that may have been from the heat of the pump. The RTD sensor seems slow to lose heat.
Do you other RIMS users use the RIMS on a batch sparge or just for the main infusion?

I used my portable RIMS for the first time and even used it to ramp up the temp as a mashout, for whirlpool and for CIP of the IC/kettle. I got almost 75% efficiency so I'm pleased. My temp correction needs to be re adjusted by about 2˚. No stuck sparges even with corn and rice in the grain bill, but the almost new march pump motor quit at one point, so I blew it out with compressed air and oiled it. All was good. I'm still getting the hang of correctly priming the pump.
I also rehydrated my 2 S-05 packets with my stirplate, which was nice as I usually just sprinkle the yeast on the wort.

Looks like i am too late, but it would have been sweet if you mounted the rims tube as the tool box handle.

That could get pretty hot for a handle.

That is a very utilitarian beer tool box you made there bendavanza.

Cheers;
