My 49 gas tank
« on: August 30, 2018, 01:00:20 PM »
So boys and girls, another first time ever project.  When I pulled my gas tank, it was an uh oh moment.  The bottom and sides had about a pound of JB Weld smeared on it.  Most was flaking off.  When I peeled it off and looked inside, it was like a stary stary night.  The whole bottom was pitted and rotted through.  At first thought it was time for a new tank.  Then hmmm, it is just a flat piece of sheet steel, let�s see if I can replace it.  Just happened to have some steel the right thickness that I got about 25 years ago that was not rusted at all (miracle), so here goes.  This is what I started with.

First off, made a paper pattern, then cut the steel.� Cut the bottom out of the tank, leaving some for structural support.� This is what your tank looks like inside.� Going to drill and mig weld to the baffle, and braze the rest.� I think it should work out fine.� Sure could use Sqid today� ;)

So far so good, got it shaped pretty well.� Plan now is to drill a series of holes and tack Weld the sheet to the tank on the edges, then go back Roll the edges and braze.� Should work OK since the original was soldered together.

So, one more problem!� Got the tank ready to Weld/braze and thought I should check out the gas line fitting.� Hmmm... seems to be plugged.� Got out a drill bit and it only went in 1/2 inch.� Clogged with something.� Cleaned it out with the bit, no problem.� Still plugged!� Seems it forms a kind of U and was plugged at both ends.� Needed to get a wire in there and unplug it.� Tried a welding rod, too stiff would not go around the corner.� Tried a length of mig wire, went in OK but not strong enough to punch through.� After fighting it for an hour and a half took an idea from my rc aircraft days where the control rods slide through a nylon tube.� Found a tube, fed the welding rod into it and with the rod inside the tube was able to feed it through to the plug.� Since the rod was inside the tube I could slide it back and forth to punch through the plug.� Like a lot of things, just a matter of figuring it out.� The tank is ready, just going to wait until I get my tank sealing stuff to finish it, it�s not like I don�t have a hundred other things to do.� FYI here is what unplugging wire, and the tank pickup look like, it is right next to the drain plug.

 If you fill the tank with water then dump it out it will still smell like gas but it won't burn
People think I go out of my way to * them off.
Trust me, It's not out of my way at all.

OK I give up.� Just ordered a new steel tank.� The bottom worked out OK, but the metal on the sides was just too far gone.� Oh well, I gave it a try, and I did learn some about brazing. :'(
Oops, out of stock for a mont(, looks like plastic tank for me.
