Caliper Bracket (Round Two):
So most of Saturday was making the bracket and all of Sunday was spent re-making the bracket as I just wasn't happy.
I changed up the design somewhat to make it easier to cut. The centerline of caliper is still on the same plane as the axle. Rather than using a hole saw to open up the caliper location, I drilled several 1/2" and 3/8" holes.
All of this was hand filed to bring it to shape. I did use the angle grinder for the out facing surfaces.
I worked from the caliper mounting bolts to the axle to make sure my measurements stayed consistent.
Here's the template, bracket one and the revised bracket two:
I removed the cable stop from the caliper and this will be located on the swing arm.
I also had to reshape the inside of the caliper, as it has a outside curve which interfered with full pad contact on the sprocket. This was a lot of trial and error.
Here it is assembled.
And mounted in place. Plenty of room for the cable and lever travel. I'll be welding nuts on the bracket to allow for y-axis adjustment of the caliper.
