I am wanting to build a new bow for my granddaughters and grandson,so. I looking to beg,borrow or steal some plans for a r/d glass longbow in the 20-25# @20" to 22" range. So does anyone know where I can purchase a set ?
Thanks for any help.

Don't know where to purchase them.  I have in the past taken 2" glass and split down into two one inch wide pieces. If I build them about 48" long I can get one and half bows from each piece of glass.  I built mine on one of my full size longbow forms and just flushed them up on one side.  The deflex and reflex probably weren't in the optimal place but the kids didn't mind at all.  I am sorry but never kept track of the stack height I used etc committed it to memory, bad mistake.
I have saw some info on them here in the past a search would probably yield some good info.  Good luck and keep us updated on your progress.

I believe binghams has both plans and a kit.
