Today I continued working on mounting the rear caliper. In order to do that I had to make a completely new hanger. I started out with some 10mm aluminium plate.
I marked out the dimensions required for the caliper to clear the disc and the relevant hole centres to carry the caliper itself and of course, to receive the axle. To make it look at little better on the eye (and to save weight
) I marked out two areas to be removed in the centre.
After trial fitting, it turned out, as I expected, there was a 3mm offset reqiured, which need a subtle bending of the hanger. The two caliper holes and the stay mount hole were all tapped out to 10mm and 8mm respectively.
Once I was happy with it and the caliper cleared the disc equally either side, it got a buff up on the wheel.
I had some bar ends and some aluminium round bar, so I decided to make the brake stay rod. Fairly simple, I drilled and tapped either end to M8, around 30mm in each end, cut some stainless threaded stud to 45mm and screwed each bar end on. Then a quick once over on the buffing wheel. To attach the other end of the rod to the swing arm, I cut a small bracket from 5mm steel and tapped to M8.
All on and done. I'll weld the bracket up properly when I get the swingarm off.
Popped the carbs on and made up a new throttle cable. Here it is as of this evening
