I'm afraid not much as of late.
I've been finding the right design for the spindle side of the bracket, the problem being keeping enough material there for the bolt to support, yet still allowing it to fit properly.
It's hard to get the right measurements for the caliper, so it's been a whole lot of guess and check. Getting a ballpark guess, make a template, try to adjust it, make another template, realize you screwed up again, make yet
another template........
I'm almost there
