<VV> non-Corvair question...

[FrankDuVal]

Blue Point makes some drive in tools that look like Torx bits to remove 
broken bolts. I see where the idea came from.:-)

My first go to tool for smaller screws or non-rusty bolts is a left 
handed drill bit. Sometimes it snags the bolt and unscrews the problem. Yay!

Snap-On makes them, machine shop tool suppliers sell them, and I am 
having real good luck with the ones I bought at Harbor freight!

On larger bolts, I go with the MIG weld a nut over the bolt. Works great 
on rusty fasteners. Quenching with water helps also. Broken part gets 
thrown away, so who cares if the hardness changes to brittle? The shock 
to the rust is good.

On Corvair exhaust manifolds here in the rusty east, I just saw off the 
broken stud and drill a 5/16" hole to tap a new set of 3/8-16 threads. I 
gave up ever trying to remove broken rusted exhaust studs out here on 
Corvair manifolds.

I prefer to center punch, drill hole, then gently hammer in a Torx bit. I also use a Snap On bit as they are probably stronger than many other brands.
