I get around 365mm for the Rover disc and around 370 mm for the Victa 24 disc, so only 2.5 mm difference in radius .
I'd just use the lathe to make the boss for the plate.
You could have this Rover disc Norm but this one looks too worn out, has lots of cracks and bits missing and rust .
Not sure if I have any more of these bigger discs ,I think they were off the early 21 inch Rovers.
I guess it just depends how much it's going to cost to laser cut all the parts as normally I'd just buy a 24 inch Victa for the blade plate ,I've seen the complete 24 mower advertised for $50. occasionally.
Looks like a good job to get the Power Torque to fit.
