I got it off, cut into it with a thin cut off wheel trying to not cut into the shaft, ground it down almost to the shaft with an angle grinder, wedged a small cold chisel in between the drive lugs and the end of the shaft and that got it moving. Cut the drive lugs off, ground some off the bottoms of the puller jaws to fit under the lug, clamped the jaws in a vice and it pulled off. It wasn't pretty but it's off with only two very small nicks on the shaft from the cut off wheel. I'm calling it good.
