want to make a glass recure 58to60 inches 45to50lbs could some one help with specs for parrel needed and riser lenth.

Old master crafters has a good set of blue prints.  its called the cat, horse, giant recurve one piece.  give them a call, they cost 10.00  also binghams has a one piece recurve that i see built alot.

I don't think Old Master Crafters has a web site, but here's Binham's.

I built this one using the Binghams 58" print/plan.
