Frode, here are some "lever" views there is a back, belly, and side view....in the side shot I marked the two drying checks I wanted to protect with the "add-on's" to the back side of the levers. They are marked A & B. Usually the levers are the Back of the bow ....there shouldn't be a height difference on the back, only the belly.
Dave 55, if you tell me what weight you want to build, I can shoot some pics of one of mine and insert the rough-out dimensions...if that would help you any? Type of wood, length of draw, and draw weight ....and I could get you real close on dimensions so you can minimize the tillering.
