Broken Bolt removal



Brad 
An oxy/ace torch is very hot and can destroy a part in
the hands of a novis. A MAPP gas torch is hotter than
propane but not as hot as an oxy/ace torch. They work
quite well for removing tough bolts and the like. They
don't cost any more than propane and are just as easy
to use.
