A friend wants me to build some seat brackets for his speed boat, and already bought all the "neccesary" material. He wants me to weld together a pair of 23" high seat brackets out of aluminum 1.25x1.25x.125 angle. I'm just not sure that this will be strong enough to be used for seat brackets for this boat(600 hp-ish).
And chance this material will be able to take the abuse?
The old sead brackets were just pre-bent 1/2x1.25 aluminum stock, no bracing of whatnot. I was gonna link the top and bottom, and add cross bracing throughout.
Thanks for any ideas and suggestions.
