Here's some progress pics to soothe the masses
Pic #1 - PVC Parts for the barrel
Pic #2 - PVC caps before drilling and tapping
Pic #3 - PVC cap after tapping for the plumbing and the gland nuts to seal around the refrigerant tubing
Pic #4 - Refrigerant tubing I bent up tonight. It has to be in that shape in order to fit into such a small diameter chiller barrel
Pic #5 - Cap with fittings attached and the tubing running through the cap with a perfect (I hope) seal.
If anyone has questions, feel free to ask. I wasn't real detailed. I did number the pics so you could reference when asking questions. Let me know what you want to know.
Hopefully Hightower will step up and post some pics of his tank so everyone can see what a nice system it is going to be cooling
