Lining a sponge bucket?
« on: August 30, 2010, 03:12:39 PM »
 Our sponge bucket is several years old now, and acquired a small hole at the bottom seam, so I sandblasted it in preparation for brazing, and discovered several small pinholes, which failed to braze.
Enter JB Weld, which we applied mixed thin to creep into the seam and holes, and I then lined it with pickup bed liner in a quart can sloshed around to coat evenly.
 Has anyone else done so, and if so, does it last?
 Worse case scenario, I end up rebuilding it- I just can't see dropping almost $200 for another.

 Never done a real bucket, but I do have a rust bucket of a '73 GMC pickup that I used Rust-Oleum truck bed liner on. There were some pin holes left after I mig welded up some holes in the bed. I also used a rubbery spray-on undercoating on the bottom side. After ~5 years now, some areas still look solid, some have blisterd with rust under the coating.

Wouldn't it be more correct to lead solder the holes.

What is the bucket made from?  Galvinized iron?  I thought the originals were wooden.  Tar would seem to be a period sealer.

They were made of iron with a wood lid.

That's it, Boom J. Let me get you my address, so you can ship it over right away. HA.

I thought about fiberglass resin, but it dries pretty stiff, and as the bucket lives somewhat of a rough life, I didn't want it cracking. I figured the bedliner would flex somewhat if struck.
Solder was out, as when brazing, more holes were opening up, and I figured that was enough heat.
And Victor, if you've succeeded keeping a '73 GMC from rusting completely away, you should be sainted!

When I had the same problem with mine, after sand blasting I poured in Electrical "Scotch Coat" and rolled it around in there to get full coverage.  After it dried I repeated the process 2 more times.  It worked for me.  No leaks.

I wish to heck that was my bucket, because selling it would put around $850 or more in my pocket, and then I could go out and get me another cannon. ;)
