Broken Tap "Burning"?

[mecevans]

i broke a tap in the turbo exhaust housing. I looked around and found a method where they actually burn out the tap or bolt with a machine. supposed this does not heat up the surrounding metal due to special cooling. would this be safe to do to my turbo? the guy i found to do it assures me it will be safe. hes asking $60 to do it.

Sounds like a load of chit to me mang. Got a picture of the tap where it is broken?

You're talking about EDM and yes, it'll do the job quickly and without damage. I'd try all the other ways first though just to save the $60...

I agree with JJ. But I thought this was "on" the car.

$60 is cheap for EDM work, it's very precise and very safe to the surrounding material, you have to ask what's the housing worth and can you replace it for less than $60.

Most other attempts to remove a broken tap will usually just make things worse, sinker EDM is the only thing I've found that works 100% of the time.

Look up "Wire EDM" it's even cooler

Wire is in there too, Crazy stuff. If i had a lot of money i would have so many cool things that i probably didn't even know existed until my money (or Supra Mania) led me to them.
