I tumble a lot of brass for ammunition reloading, so I know how well this can work. I'm always a bit leary of getting near a used gas tank with a torch. Lou you're braver than I am (and clearly a better sweat solderer!)


Meanwhile, as I have the engine out of this 123, I discovered a brazed crack in the frame. The brazing is cracked too. While I'm anything but a good welder, I'll get the grinder out and try and get rid of the brass, groove the crack a bit and see if I can wire weld top and bottom.

It's about this part of the process I have to remind myself what it is I set out to fix :-)


Oh, and the driveshaft pin hole is egged out. I'll split the tractor and see what the front of the hydro shaft looks like....


I suppose after 55 yrs things DO wear out....
Been my experience where ever there has been braze, it gets into the "pores" of the metal and trying to weld it produces Spatter/porosity like the metal is very dirty,
And I have wound up with a mess, even if ground away, I can't get it all out.
As far as parting a tank at the seems:
some are spot welded, some are seam welded/rolled résistance welded.
Few are just furnace soldered or furnace brazed.
Just my experience.
Myself, I clean up the loose scale and put the tank in use.
If storing a cleaned tank, do as others said, oil it inside.
Fuel in a tank has vapors which precludes moisture laden air, so rust mostly does not occur.
