No recommended changes other than upgrading to a 1460 and using it more in my neede applications and limit the use of the 1850.
So will try and get pix tonight of the solutions, but spent the day at a local steel place. Talked with the engineers and ended up short on solutions. I am leaving it in my mechanics hands as he has a better idea of what will fly.
But to describe, what more than likely he will do is take a piece of 3/8 flat stock, heat it and wrap it around the ball. and weld it down. The second plan is taht I bought some thick walled tubing and he can cut a tube out and put it over the other tube. Problem is that the ID of the tube is 2.5" and the OD of the ball is 2 5/8 so an 1/8 of an inch has to be taken off. I tried to grind it out in advance and it did not work. I think I need a metal lathe and that would do the trick.
