I just made my brace out of 1" angle iron and so far it's held up to any abuse I've thrown it's way.
Thanks Dave, yeah I may need to brace this one also, I cant notice any flex when I sit on it but I may cut out two small triangular shapes and weld them on each side of the bend.

I used my 4 1/2" grinder with a 1/16" Dewalt cut-off disc and just cut through enough so that I could bend short section over until I had the angle I wanted and the I sewed it all up real good with the hanged rod, mine was cut completely in two so Im thinking by doing it the way I did it has retained a good bit of it strength, I really dont think it will ever fail on me, I may add the braces just for insurance

The bsouth end of the north bound mule dropping down on the rear tire at 40mph would be an ugly event that will bring an entirely new definition to a "skid mark"!
I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
