Fixing hole in tank

[Junk Meister]

All of them, I wouldn't have listed them otherwise. @srcarr52 welded countless chainsaws cases and cylinders both saving them from the scrap heap.

@srcarr52 @tree monkey @dall
just a few off the top of my head around here besides all the welding shops out there...

You Should go a bit farther.. Do a search on @srcarr52 and others. Look for some pics of above and beyond Quality Welding and Machine work. There are some impressive posts right here on OPE

As far as drilling and tapping it- I am not saying it wouldnt work, but you have to take into consideration how thick that metal is- ist it even thick enough to get even two full threads in it, and pipe threads are spaced apart bigger and although there are straight pipe threads most are on a taper. If I was dead set on going the drill & tap route ( which I would not do personally ) I wild use the smallest diameter with a fine thread pitch to get the most threads in there. Just my 2 cents / opinion.

Have you ever actually looked at 1/8” pipe thread? It’s very fine.

Yes- I know they are more than 1/4-20 but probably not as much as 1/4 fine bolt thread which I know is a 28 pitch, Its probably between the two

I got one of those Card charts in my tool box somewhere- think its made by starrett, its probably in the drawer with the tap & dies ,drill bits

My first thought was to put the screw back in. Lol

Well the screw isn’t tight anymore after pulling it out haha.

 

[jacktheripper]

I don’t think there’s enough meat in the thickness of the case to tap it and screw a plug in.

I’m leaning pretty heavily toward just putting a nut and bolt in with a grommet or rubber washers to seal it. I can access the hole through the gas hole in the top with long needle nose. With a rounded head screw, it wouldn’t really stick out too much on the bottom. JB weld with fuel tank sealer would be great, but that sealer is so dang expensive.

That was my point

Some shelving like you would see in a parts room (Usually gray) used a 1/4"NC stove bolt with a flat screw driver slot and the head is fairly thin/low profile and a larger diameter stove bolt head on them. If you got the tank clean and a way to get the machine bolt started in the nut (Nut inside the tank) then get your JB weld smeared where it needs to be and tighten it up and be sure you see the JB ooze out all around the head. You might be able to tack (Not weld solid) a length of wire or rod to the nut and then break the weld after all is tight and JB is cured. Good luck.
You might find a shouldered nut with locking face I can't think of what they are called, and it wouldn't spin as you tighten the stove bolt. Similar to your Idea in last post but bolt going up and in and JB for permanent instead of rubber washer,

I would not worry about the tank sealer, generous amounts of JB weld on both sides around the bolt will work fine.

I would favor JB Weld, grind or sand (coarse grit) around the hole, JB all around, press in a piece of screen wire and finish with JB over the patch.

That hole is right next to a seam which is probably glued so welding is probably not an option as you'll burn the glue out.

Jbweld is what I've used on a dozen mag tanks, the sealer is a little $$ but the can I bought is probably gonna last me my lifetime! Just cut it with acetone.

Well damn you pretty much know everything huh??

I have one with jb weld. Its not pretty but it doesn’t leak.

Not taking the bait

You ever been to Ricketts Glen park?

SOME of US were born that way. Then sometimers gets in the way.
