He has now has a new engine with a two bearing crank.
The original three bearing crankcase was a little far gone to 'hack out the middle bearing' so he replaced it with a two bearing crankcase and new crank.
He had a two bearing crank before it broke
You are correct of course- I was confusing two failures.
The one under discussion was a two bearing ADI process crank- he wanted to build a three bearing engine with new crankshaft but the only three bearing crank available was another ADI shaft and he wouldn't use this.
He now has a replacement two bearing crankcase with a Phoenix crank.
