Hi Ironbark,
not sure exactly what it is you are trying to achieve. I replace the Victa stubs all the time because good Victa wheels are hard to come by and I always end up with reasonable wheels on 4 stroke mowers, because the motors on them usually fail much earlier than anything with a 2 stroke on it. All I do is grind the back of the stub off and punch it out. I then remove the donor stubs from the axles, usually have to put them in the lathe and turn to fit, then arc weld them back into the Victa axles. The one that does cause me grief is the stub behind the height adjuster handle, I have to remove that before I can grind the back off and weld the new stub in. Time consuming but there is not much else I can do.
I try to get the stub as square as possible but if I get one a bit off I just hold it in the vice and give it a bit of a tweak, you can never see it.
Done countless numbers this way and never a problem, bit of paint and you would never know
