Slight change in the plans. I found the piece of aluminum diamond plate for the platform and got a 4" U-clamp to attach in the rear, but the main change will be in the rear. Instead of having the rear supports come from the rear of the rack to the axle, those rear bars will be shortened and mounted to the rear unused V-brake mounts. This rack and design is still in progress.This is the crap I do in my spare time. These kind of projects costs nothing except the silence of the voices in my head.
I hear people say "Why not buy a rack on Amazon for $30.00." or something like "You can buy a rack cheaper than your time." but this is what keeps me doing cycling related stuff interesting during the winter months. It's called preparation for some hardcore commuting!
