Noah used this one to solder collars on the unicorns.
Jeff: I've got a tank here that's solid, has a repair at the outlet, doesn't leak, and I'll trade it even for your "screwed up" one. It looks dirty inside, but it seems to be solid dirt. While I'm here, I'll mention that I'm in favor of sediment bowls as opposed to the in-tank filters on the wide frames. I'm also dropping a couple .50 cal. lead balls in the tanks to keep things stirred up. Vibration has to be good for something!
I'd forget repair. I'm sure there are many folks on this site that would have that tank as a spare. That's a fairly common tank, I think I have a dozen of them. Try sponsors first and if that's not cost effective try placing a want ad on this site. When buying from a sponsor you generally know what your getting. If the budget is tight and you go with an add be sure to ask questions before you buy. A rusty gas tank can be a major safety issue.
I love that old soldering iron. I have a decent collection of older hand tools. Brings back a bunch of memories of my grandfathers garage/workshop. Now if I can only find someplace that sells gas and oil scented air fresheners.
On the tanks, the ones I have are for future restoration projects.
Leaky Gas Tank Revisited
The BOOMERANG Tank:
Back from Pennsylvania:
Getting a bath:
After an overnighter in electrolysis tank:
Cleaned up well:
This wasn't the way to go:
This is an epoxy that my neighbor had given me. Not sure what it is - seems to have bits of glass in it. Needs to be mixed a small bit at a time.
This tank, as Jeff can attest to, is clean as a whistle inside. This rust was on the outside, near the strap clamp. My best guess is that years ago the strap got tightened hard enough to crack the paint, letting moisture collect.
Don: I was hoping that particular pic would draw KK away from his fishing pole. This was easy/fun experiment/work. Also, kind of a riddle as to why this tank rusted from the outside when it's so perfectly clean inside. I'm going to finish it up with a nice paint job, install in on Penney (Hi, Steve Mitchell) and run it next summer to see if it stands the strain. My tractors are ALL works in progress!!
Got your email. This is the stuff I used to try to clean the inside of the tank you just got:
It went in clear (on the left) and came out brown. Probably several more treatments would really help the inside of the tank, but that's why I say I really like a sediment bowl - good gas, some MMO, and keep the sediment bowl clean!
