One of my metal stock tanks sprung a leak, and of course it's near the bottom. Normally in warm weather I'll empty it, clean the spot and use JbWeld. If the hole is over 1/16" I usually use the jbweld and glue in a short machine screw (not a sheet metal screw that animals will get hurt on). However, this time the tank is frozen to the ground, it's severely cold outside (around zero), and jbweld will unlikely dry, not to mention a wet tank. The hole is about 1/4". I plan to take a 1/4" bolt, with nut, metal washers, and rubber washers between the metal washers and tank. The problem is where can I get a washer with a 1/4" hole? Sure I can make one, but I'd rather just see what the hardware store has. There must be some plumbing type of washer. Otherwise I got to buy sheet rubber and all of that. Even if it just holds another month or two, until I can use the jbweld.
I have done this before using the neo-washers from pole barn siding screws, on smaller holes (and it worked well) but this is a larger hole and needs a larger washer. Any ideas? Needs to be a common item from a hardware store, farm supply, or auto parts store. We dont have any specialty places here in farm country.
By the way, would leather work? I got a piece of an old saddle strap. If this snow keeps up, I may have to use what I have laying around because I wont be getting to any stores for a couple days.
