Hi Wigan Lad
The disc is fastened to the wheel with an aluminium centre,
Pic also shows the inner ball bearing, I used the original outer bearing due to lack of time, I plan to look at using a sealed ball bearing when I have more time, if it is possible
Before drilling and tapping for the disc
The rear of the aluminium and the inner wheel, cut down
The fixing
Another close up, shows the folds on the plate better, 45 deg fold on the front to add extra support
The plate is folded under the frame and is held with the frame bolts through the axel bearing housing, and two bolts through where the brake shoes were mounted. The bearing housing I trimmed the shroud off, you could just reverse it but I think trimming it makes a neat finish.
I will take some more pics tomorrow, but it looks like any other standard C5, I like to think of it like a wolf in sheep's clothing.
I am unable to fit the front wheel covers without cutting them, so I have another set of forks were I will mount the calliper on the rear and hopefully this will allow fitting of the covers without having to cut them.
Also thinking of adding more gears but recently moved house and will have to put some time in there soon, I will help with questions and post more pics if anyone wants to know more, watch this space !
PS the brake disc is held on with csk bolts allowing a closer fit to the plate, there is only a few mm clearance to play with.
