You do not need a bow press to put twists in your cables. You just need a hex head wrench. Take your bow and press the cables toward the riser, this will rotate your cams. Rotate the cams enough so you can put the wrench on the outside of the limb into one of the holes in the cam. This will take the force off the cable and you should be able to remove the cable and put twists on it. Only do one side at a time to be safe. I've done this many times on my Cybertec.
