made a start on the rear caliper bracket, usual thing, work out where it's going to be mounted,[underslung of course, me and dangerous arguing about the torque arm, is it better to mount it in a 'pulling' plain or a 'pushing' plain?, think about it, it's not as simple as just making a hanger], the obligatory cardboard template, work out the centres and drill clearance holes before chain drilling and milling to shape, from bitter experience you can spend a load of time getting the profile spot-on and then drop a bollock when you drill the mounting holes.
