I thought about making a sleeve and welding it in as well (great minds think alike. ). My only concern would be if there is enough "meat" on the arm to do that and keep it safe. Steering arms on tractors can take a hell of a beating. Tapered end mills are available, but are pricey and your chances of using it for something else are slim. A D-reamer would do the trick and you could make it yourself, but you would likely need to step bore the arm first to get it close to size.
