Arwyn,
You may not have had any trouble with welding causing distortion on the KP tube but MMC have had, my first Morgan (a 07 reg +4) was such a car. When I renewed the KP bushes (at 15K miles) the first axle went without issue but the second one did not. On checking the axle in the lathe there was over 15 thou TIR runout at the lower end of the tube.
Fortunately Peter M at Mulfab helped me out with the supply of some bar ends of the material he used for the bushes. I made my own bushes and left the I/D small to allow for the machining. I bored the bushes in one setting and left a thou or two for final reaming. This covered your point of accuracy. Your other point about balancing is valid and was solved by bolting weights to the axle, not using a fast spindle speed also helped.
The hardest part of the whole job was cutting the lubrication grooves!!
Just seen your last post, time is not money to me so I push out one bush at a time.
Rog, Your elliptical plate will work, just as my round with flats on did. Using a press is just easier than using a draw bolt.
