Guess what? I'll be spending some time at my Brother in laws house for this one. You see when you said trapezoid I thought why do I have to get one of those things I see kids jumping up and down on in backyards. Oh! That's a trampoline? Any way I will be hands on but with a toolmaker/Machinist/Army armorer looking over my shoulder and why lie in the end he will do the most work so I won't bodge it up. Patrick, I'll use your info and when he gets time when our other project is done I'll get to it. For now thanks again, and HAPPY NEW YEAR. Dave
