[TheForge] repairing tapped sleeve

The gas turbine mechanics' friend......helicoils
helicoil inserts are a life saver. They are great for stripped out head
bolts on engines, and on power generating gas turbine, every joint bolt hole
has a helicoil insert. You know you are going to tear up the threads so why
not make them easy to replace....;-)

Subject: [TheForge] repairing tapped sleeve

I have some machine parts that need to be repaired. They consist of a steel 
sleeve that has the inside threaded to 5/8 NC and the wall of the sleeve is 
worn completely away in some areas. I can cut out the sleeve and replace it 
but that will be real pain in the neck. I tried to find some carbon rod that

I could thread and screw into the sleeve and then build up the wall with 
weld. I haven't found any carbon that will work. I wonder if a copper rod 
will work?  I looked at copper rod in the McMaster Carr catalog it shows a 
melting point of 1981 deg F. I'm afraid that's too low. Any ideas? 

Thanks in advance, Dan Cruzan
