best ever home made catapult (by me)

heres wot i believe to be my best yet.i think the hardest thing to do wen making a catty is make your design i believe ive not seen one like this its based on a starship made with a mild steel frame and a pine carved ergo handle and wrist brace the handles got sum unknown wood capping the bottom stained with antique pine .ive been thinking about making a few of these to sell them wotcha think ?
cheers grant.
