First I started with the dimesion that Perrydasavage had posted in a previous thread:
Picture #1 - I purchased this from Home Depot. I believe it was 3/8" but I might have ended up with the 1/4" because I knew that I only had a pair of vice grips and the use of leverage in order to make the brackets. I first sanded it down because I knew I wanted to primer and paint them.
Picture #2 - I clamped a pair of vice grips onto the area labelled #1 and then took a pair of needlenose pliers at point #2 and then bent the rod around.
Picture #3 - Then I just followed the dimensions Perry had posted and would clamp the vice grips at about the right length and bend the rod to the right angle.
Picture #4
Picture #5 - Once I got the brackets completed, I primered and painted them a flat black. You can see them on my bike in the pictures below.
Picture #6
Picture #7 - The right side is a little bigger than the left side. I thought about re-doing it then realized, hell - no one's going to even see them once the saddlebags are on.
Once I bolted them under the fender, I then bent them into shape the way I wanted them to fit. So far so good. I even use them to hook my bungee cords to when carrying something on the back seat.
