Re: Old dog learns new trick...Welding!
Thanks for the suggestions. I did not want to keep on welding because I don't trust my welding enough to keep at it, keep grinding down smooth... maybe I will screw things up good that way. In spite of the thickness of the metal, I did blow through twice, but also got it fixed again.
Another thought which came in the middle of the night was sealing it up from the outside with solder. I might do some experimenting today to see if I can get solder to flow and bond.
The baffles (braces actually) are a concern, depending on how thick the commercial sealer is.
One thing I know. When I hear people complain about how much it costs to buy an in-frame hand made tank, I want to tell them they have no appreciation for what is involved. I think that Sportscarpat's tanks are a bargain for what you get. Stainless steel no less. That guy is good.
I'll let you know how the solder goes.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
