As it turns out, I measured the stainless that I used and it is more like 22Ga. (0.032"). From what everyone is saying, it looks like 1/8" (10Ga.???) or thicker is the way to go for a rigid mount that doesn't flex. I had thought about using those little 'rubber feet' like Matt uses, but I want to keep completely off the fork shrouds if possible. If I had access to a metal brake I'd bend a couple of angles into it for stiffness, but all I have is a POS bench vice that's about 40 years old and rusted.
The braces I made help a lot, but hopefully I can redo
my original design and get rid of them. I kind of like the two piece design like the ones Phil made up (shown in original post), but was concerned about messing up the fork clamp (from rubbing and vibration) where they go over the front. If I can get some stainless thick enough, the
single piece design should do the trick (sans the braces). I sure do envy you guys that have access to a machine shop. Hey Phil, was the bag hitting the fender due to the action of the front forks allowing the fender to push up into the bag, or from the bracket itself flexing?
