Looking for some advice on what to do next.
Bought a 1945 AGMCO at the Madison get together in March, it was my most desired item going to the swap, so was excited when I found one in great shape. Noticed at the time that the left valve was froze up, but decided to wait until warmer weather to dig in.
When I got back to it I tried heating the valve with a small, then larger propane torch, but to no avail... that's when the trouble started.
I started to tear down the valve working my way down, when I went to spin out the valve, the threads soldered into the tank spun, and now I have a leak where noted in the last picture. (tested it by putting a small amount of alcohol in the depression with air in the tank and bubbles come out the seam.
One question, is this a common failure point, if so was there something I should have done differently (other than trying more heat first?)
Hoping someone has a good suggestion, the best I have come up with so far are:
1) Replace tank (I have concerns on how I avoid the same fate in the next tank)
2) Try and re-solder the seal (not sure how I would go about that, and not really excited about trying to repaint the tank)
3) Try and seal the tank from the inside with POR-15?
4) Other suggestion?
Thanks for reading, and thanks in advance for any suggestions.
