Had to modify the original hubs to fit the XR2 discs, the discs have a taper leading to the flat face on in the inside. A careful amount of fettle with a file to add that taper to the hubs was done and it fits perfectly. The final radius of the hub was not touched, double checked by fixing a bit of plate to the knuckle and pushed against the outside edge of the disc, span it a full 360 degrees and had no gaps created so it runs true still. Wasnt aware I'd have to do this but I'm happy with the results. I could have put this in the 4 jaw on the lathe but i really dont have the time to sit down and true it all up. Next up over the weekend is the brackets for the calipers & driveshafts. Just no time to get machined ones made so I'm going to push onward. The other knuckle has been stripped down and ready to be painted after attacking it non stop for 3 hours, along with the servo and the servo bracket. First thing ill do tomorrow is strip down the brake bar and prime it for paint.

See the last image, that final lip inside the disc is the taper I was talking about.
