ive been watching you build this bow clsely mr pat. ive been curiousabout your form that you use to heat in reflex. what you made it of, pine 2x4, spruce ,some type of hardwood like oak perhaps? ive also been curious about the elyptical shape, how did you arrive on that shape? im a carpenter , and know how to make an elipse by using a mathimatical formula. does this work for bows or is it different. or did you just eyeball it? ive also been wondering when you use oil on the limbs, do you just apply the oil on the belly side or on all sides? do you use the tin foil over the form as a sheild to keep oil from dripping on your form? just been very curious!!! ruddy
