When is a tank too far gone?

[Gregory]

I has so much luck in repairing pin holes in the 821100e tank that I broke out the 78skunk tank to try my hand at it.

It has MANY (at least 20) pinholes that I plugged as well as several that were much larger. I was able to seal all of them down to just a seepage level until I got to the one in the picture.

I had planned on stopping the rust and double or triple lining with Caswells, but not sure now.

I have a mig welder but I am pretty sure it would just burn through this thin stuff. Is there anything I can do on my own to repair this tank?

If you are skilled with the welder, cut that thin area out and weld in a patch.

If not so skilled, get someone who is to do it.

I was gonna say the same thing. Its on the bottom so just cut it out and braze a patch over it and leak test it.

Not to redirect the question, but I did think of a way to procure skunk tanks cheaply...well sort of.

I could make a rubber mold of the indent, then use it as a form for bondo-ing in an indent on the much easier to find 79+ tanks.

Any info on how to braze? Is it something I can purchase cheaply?

I actually have another loaner tank that I could cut the base off of to use.

If you don't know, you need someone better at it.

Not a good first timer's project. Someone like Chuck could do it a lot better.

Brazing is done with Oxy / Acetelyn torches and that gold brazing filler rod. You got a set right? Got any buddies that can modulate then flame low enough to not just melt the area worse and do it for you??

[GregT]

The problem with brazing patches into a tank is the flux left on the inside.
You can never remove all of it, and as it's slighly acidic it's a great spot for more rust to start.

far better to fusion weld - either oxy acetylene or a MIG turned well down.

[chuck hahn]

You can braze with uncoated rod.

[Gregory]

I have an acetylene torch but haven't tried brazing. maybe my neighbor knows how to do it. Just hate for a good skunk tank to go to the scrap heap.

Smallest tip you have and practice on some scrap. Thin stuff like duct work ( but without the galvanizing ) is a good place to start. Or you can burn off the galvanize and use the raw metal then. Wire wheel the soot off it and start playing.

L tanks are great to practice on.

I guess I will have to do some playing with it. I will get it figured out one way or another.

I thought I had a bike bought that had a skunk tank, I(t was a 79 but had the indented tank), but he just called me back and said it sold already dang!

I have a line on another skunk tank as well so my fingers are crossed.

I think brazing is going the same way as lead body work its becoming a lost art

[chuck hahn]

How about doing Oakum and lead sealing on cast iron sewer pipes?? Yup Ive done lots of that too.
