half a broken petcock stuck in the tank - 50V

Back again with a dumb problem rather than a dumb question. I was removing the petcock when the years of gunk over powered the metal and it snapped.

What's a good way to remove it? (edited)

Left handed drill bit on an impact will do the trick

Dont have access to any power tools until next week. Any mcgyver type solutions?

Re: half a broken petcock stuck in the tank - 50V

Got a strong grip and straight circlip pliers? You can set them to "open when squeezed" and shove em in there grip the hell out of it and try to back the thread out.

Try hammering in (gently) a torx bit?

Its got me out of similar situations.

Looks like the tank needs an acid bath anyway, plug the hole, fill the tank and let the acid devolve the aluminum remains while cleaning the tank.

Re: half a broken petcock stuck in the tank - 50V

You might try a flat screwdriver on a leftover edge and hammer in the off direction .

Maybe apply some penetrating oil .

If it's really stuck , you might try a hacksaw blade in the hole to cut slots in the aluminum and then push the leftover chunks toward the center of the hole . Keep a needle nose pliers close to grab the loosened pieces .

You could grind it flat then screw it into the tank and retrieve with magnet.

You have a magnet that attracts aluminum ?

vinegar will dissolve the petcock faster than the steel,ask me how I know.if you have a small hack saw blade you could notch it and try to turn it.

...and it's a tapered thread, so it's only gonna get tighter threading it in.

I call these my aluminum and plastic "magnets". ;)

Re: half a broken petcock stuck in the tank - 50V

I came here to make the torx but suggestion, it's been my go to for this sort of thing for years and works like a charm, plus every drill set you buy comes with a bunch of torx bits you'll never use just so they can say "110 piece toolkit"

Ha . I have one like that . Works great for those tight spots and even starting a bolt where I cant fit my hand . Both the hole and bolt has to be pretty clean though . But , that doesn't happen very often , thankfully .
