Oh yeah, would definitely be too weak for the fender. Since I had the remnants left over I opted to test out the process again and make this piece to ensure I have the bolt pattern down before I wreck a piece of aluminum. Since I am going from Maryland to Missouri I will not have the bike with me when I fab the bracket so I need to be spot on.
Over all the fabrication went really well. I let everything sit for 12 hrs then pulled the weight off of it and ran the heat lamp to finalize the curing process. Sure wish I had a band saw here! Would definitely be a lot easier than hacking it all.
