Another possibility for removing broken bolts

[drspiff]

I was wandering the 'net looking for information on building a TIG welder, and stumbled across an article on using left-hand drills to remove broken bolts. Here is the URL: http://www.madelectrical.com/workshop/broken-bolts.shtml. I have not tried this technique, but it may be of interest if you are looking at one or more head bolts or radiator casting bolts.

That same procedure (in different wording) has been posted by several members at different times and may even be in the how to section.

I know several on the forum have used this method successfully. It also helps to soak with penetrating oil first.

My Dad sucessfully removed a sheared off bolt yesterday in the area where the PTO cover plate bolts to the back of the tranny housing. He simply placed a nut over the bolt hole and welded all of the inside of the nut. I didn't think it would work.....but lo and behold....it did. Turns out, the bolt is steel, the housing is cast.......weld doesn't stick to cast. Using a crescent wrench.......it backed out with ease. He's never been fond of the bolt extractors. Why did I ever doubt? 50 years in the machine shop......got to count for something.

I have been using left hand drills for years, wouldn't be without them. My only caution would be to buy a good set, the cheap ones are just that....cheap!
Snap-on makes a good set of extractors but even they fail more often than not
