[Farmall] broken easy out

[Greg Hass]

First of all, I don't purport to be an expert on this.  My statements are 
just based on my experiences.  I have used the method you describe only 
once, and that was on a cattle waterer where the bolt had rusted in and 
twisted off.  However, in this case it was a little less than 1/2" thick and 
I could blow the metal straight through the bottom.  It did work nad all I 
had to do was run a tap through to clean out the threads.  I did this only 
because it was too far away from any source for a welder and was fastened 
down so it could not be moved.  I am thinking this method would only work on 
cast iron and not on steel, as the steel would get too hot and the threads 
would be destroyed.  I would greatly prefer the weld method over the heating 
method, although I think I would try the heating/blowing out method before I 
would ever try an "easy out".   Before trying it on something as important 
as one of our old tractors, I think I would try to find some junk casting 
that either had a bolt already broken off (or where you could knock the head 
off of a bolt) and experiment with that just to get the feel of things 
before atacking something good.  Hope this helps.  Perhaps someone on the 
list who has actually done this on a larger casting will chime in here.
