I made up a tool this morning. Rather simple, but should work.
What's it for? Well look at these.
It will hold a spindle so you can install a new piece to fix it. A few of our tractors have the issue of breaking a spindle and this will aid in repairing it. I built this for Ford/Jacobsen spindles, but with a little modification, I'm sure it would work on other brands. I hope to try it out before too long. Main thing will be getting some stock to replace the broken part.
