Then just to add to the thinking, I stumbled on an unfinished rostand part that matches the original tiller head....
here is a lineup of the HA 1.5" part, my wornout original and the rostand 1" tiller head on the right.
you can clearly see the extra meat in the HA part as well as the wear on my old tiller head (note i no longer have the original pattern tiller part of this pair of castings)
