A little time modelling with paper and pencil or CAD software can save a lot of grinding. And there are a number of online calculator websites that can help calculate the hydraulic forces and pressures required. When I built mine I had the geometry pretty much worked out in advance:
I'm working on designing (actually, adapting an existing design) a FEL for my B7100. Does a 5 cu ft. capacity bucket sound about right? The owner's manual indicates a limit of 500lbs capacity for a FEL. The same manual indicates a 42" bucket width, but the tractor is wider than that. I'd like...

NOTE: you will see I played with the link idea and had that geometry worked out but in the end abandoned the plan due to the added weight. The extra steel doesn't seem like much at first blush, but really does start eating into the meager 500# lift capacity envelope I was aiming for.
