So today I was able to come in work early and got started on my intermediate shaft that goes in between the 231 and 300.
I cut a portion of the 231 shaft where it goes in the mode hub, and a portion of the aw4 tail shaft.


Machined the 231 shaft and then bored out the hole in middle of it to accept the aw4 shaft.
Pressed it in lightly


Laid some tack welds then preheated it to 450 degrees

Put it on the turntable and did two passes



Post heated it to 500 degrees then out in the oven to cool down slowly for 6 hours.
Then sandblasted it and polished the bearing contact surface at bottom of the shaft
