Idid wonder if drilling a few 1/8" dia holes in it to get penetrating oil farther back would hurt the shaft?

Dont really know what is best. . . . I think I would rig it so both offsets were on the same side of the shaft and then change the offsets together to the other side. Back and forth. Then maybe step 90 degrees and go 180 back and forth from there. Bowing it sideways in comparison to the 1st positionings. You have a good setup. Keep using your ingenuity.Spyder
Are you saying rotate 180 from each other or 180 for both?
Exactly! There is a science to using heat. Not exact science, but still. And the quicker you heat the outer shaft the better, before the inner shaft has a chance to absorb a lot of heat. Once the inner shaft gets almost as hot as the outer shaft, forget it and let all cool down to ambient temperature before doing anything else.Yes -- and glowing red will anneal the shaft, not to mention cooking lubricants to lacquer. - - - Clean the metal surface and look for a surface change from clean silver to straw-brown. Bluing happens next. There and up is the danger. You can ruin the shaft.
Yes! Heat it fast no further than blue. Tap on it some - then cool it fast with a blast of water. This will affect the outer tube first and it will try to move stressing the rusty interface between the 2 shafts. The real chance for a gross move is during the heating but dont waste the quick cooling shock. Every tiny relative movement puts you closer to a slide.Exactly! There is a science to using heat.

When ever I had similar situations when a lot of heat or rapid heating was required, I always used a oxy-acetylene or oxy-propane torch with a rosebud.
