Can JBweld fix my tank?

If I knew how to braise, this would be easy.
Since I don't, what is the best method to fill these holes?
 
I thought about solder, but I'm not very good at that either.
I'll give it a try. Any particular solder?
Since it will be painted, acid core should be okay, right?
 
It worked on my tank. I accidentally drilled through the tank when I tried to remove the brackets that hold the emblem. I filled it with JB Weld and it has been fine a year later.
 
I wouldn't trust JB weld for very long. It's an epoxy and alcohols such as ethanol soften epoxies.
 
i brazed my tank with luck..but was worse hole then pictured...

after a whole brazing rod an the tank shooting across the shop i decided to buy a used one
 
As Wally says soft solder is a very good way of doing it, the area has to be spotlesly clean and use proper old fashioned flux and an big old fashioned solder iron that way you can spread it about because the holes you can see are not the only ones that are there soon to break through, really I would braze it if you can p**s, you can braze all the same principle, its all in the preparation.
I did an old tank that I was going to chuck out, that was brazed all around and all where I thought it might be thin. A very satisfying hour. If you really feel you can't do it then get someone else to do it. These tanks are getting thin on the ground these days so really doing the job properly is an investment.
 
I like the Caswell idea, but I'll save that for a later date.
For now, I'll try solder. Then sand it down and primer it.
I need to get the bike running soon, to justify spending more money on it.

Thanks for all the info.
 
Im pretty sure JB weld would work just fine.

From the JBWeld site:
Q: Is J-B Weld resistant to water and/or gasoline?

A: When fully cured, J-B Weld is completely resistant to water, gasoline, and about every other petroleum product or automotive chemical. For wet-surface or submerged water or gasoline repairs, see our J-B Stik or Waterweld product information.

Why not JB the holes..then do the coating as suggested..then sand down the JB and leave it at that.
 
Ethanol is not a petroleum product. I used JB weld in an Autolite carburetor a few years ago, it softened up in only a month or so. It never did actually fail I guess, but it was soft enough to dig a finger nail in it. I did notice that it hardened up again after I had it on my shelf for a while.
 
jb works on about everything but i tried it on my truck gastank, it peeled off, i also tried the gas tank repair 2 part stuff ,its just like jb weld. it didnt work either,maybe fiberglass then jbweld then bondo,/primer/ paint

its in a real bad area , because gas sets down there all the time, and if it builds pressure inside the tank,it will push out the epoxy, so maybe good fiberglass, like they made race tanks out of or some coating inside will prevent further damage, i hate to see you go through all the work and it fail on ya
 
Searched my pic files and heres my answer..I mig welded the holes shut, JB Welded over the welds as a micro crack sealer, then coated the inside and finish sanded the JB down..sent to Nvr2old for paint.

I was going to solder it, but my iron was dead.
So I JBwelded earlier today as a temporary solution.
I'm sanding it down in the morning and then I'll apply primer.
I'll order some Caswell and do it right before painting in a few weeks.

I'm also looking around locally for a cheap tank.
If I find a good one to use, I was thinking of modifying this one for a custom look.
Maybe cutting it down and adding knee pads.
 
You can heat the tank with a propane torch and while its hot apply the solder (I think, this is what I would do anyways). Just make sure the tank has ZERO gas in it.
