Todays Project - What did you do today?

[Mayhem]

Hi Brett,

I used a chunk of 6160 aluminium for the bracket. I actually printed up a round piece to match the diameter of the radius on the caliper, with an eccentric pin that was a press fit into the hollow rivets that fixed the disc to the hub. That allowed me to position the caliper correctly on the disc, so that I could take a picture. I then imported the picture into Fusion 360 (free 3D CAD) and resized the picture, so that the bolt hole centres on the fork mount were correctly spaced. From there it was a case of filling in the gaps.

I am lucky, as I recently purchased a 3D printer and was able to print several iterations until I got the one that fitted correctly and didn't have the caliper hitting the spokes. If I didn't have the printer I would have wasted a hell of a lot of aluminium.

Having said that, I could have made sections out of flat bar that lined up with the bolt holes and welded something up to base my measurements on but the printer was perfect and cheap to knock out the test pieces.

As for the cost of parts, I have no idea. I've just noticed that my location has vanished from my profile. I'm sure that I haven't been deported, so I'll have to go and sort that out...
