If you can get your string and cable lengths, you can get them made fairly easily.

As far as presses, they all pretty much work. I havethe WWAG press, and it works flawlessly. I've gotton desperate in the field and made a "press" by placing two strong sticks on the outside edge of each limb and used a treestand ratchet strap to draw them closer. I put a t shirt under the sticks as to not scratch the bow. Was it safe? seemed like it. would i recommend it? only in an emergency, because something could definitly happen. Just keep those fingers away from the string groove - that goes for all presses!
