Sorry about that AC the pictures are much to big. I resized a few. Most the others are not important since I had to change up my design.
This is the way I brazed on a propane valve for the small cooking bottles.
This is the finished product and going into my gauges to test for any leaks.
Here is where the change happened. I could not get 30 feet of 1/4 refrigeration copper to coil in the tank without going to the top. This really was a problem because I had planned on simply brazing on an old hacked element base and continuing to screw the coil in. So I just uncoiled the tubing and and ran in it the bottom element hole and got it to coil at the bottom.
I used teflon tape and joint compound with a 36" aluminum pipe wrench to put it all together. I will finish the back half tonight. Idea is to braze the coil through a 1 inch bass cap then tighten the union down. I'll post more picture at the right size from now on.
