Just to update.
I have now brewed 5 batches on this rig.
The heating element was kicking my butt. I ended up trying a 110V element in the RIMS tube. That didn't do any better. I put a 220V element back in and re-wired the relays to supply 220V to the element. Had to change a few other aspects of the wiring. Added a 220V cord and plug. Then split off one leg to get the 110V I needed for the motor and PID.
Next issue was now I would way overshoot my temps. Silly me never did auto tune on the PID. After that things seem to be doing much better. I have a 2 degree difference between what comes out of the RIMS tube and the temp in the Mash Tun. I can live with that.
Unless there is a way to do an offset on the PID. Will have to look into that.
I also ended up replacing the false bottom I was using. It was from my old 10 gallon Gott cooler and it just wouldn't seat right in the bottom of the keg. I ordered a S.S. false bottom from NB and put it in. Had to cut a couple of notches in the keg opening so it could slide in easily. It fits perfectly in the bottom of the keg. I had almost no grains getting by it after the grain bed set.
Things left to do.
I still need to put in sight glasses on the HLT and the MT. I have the stuff. Just been lazy.
Purchased a couple of BBQ pit ignitors. Want to mount them to light the burners.
WIND SHIELDS!!!!
Now that summer is here I need to make another coil to immerse into an ice bath for wort chilling. My ground water is already up to 70 degrees. Pretty soon the immersion chiller won't be able to cut it anymore.
