the background on my bo is that it started as a hickory-backed hickory longbow, glued into a 2-3 inch reflex. things went fairly well, untill i got to the final tiller, when i went too far!(i wanted about a 55 lb. bow) as things developed, it was clear that i was on my way to a nice 35 lb. target bow, so, having been facinated by the entire concept of the penobscott, i decided to add the backbow. the results were what i was hoping for! the bow now has a working draw of 52 lbs. and has been shot a couple of hundred times now. besides enjoying the fruits of my labor, i love the attention it draws(pun intended) whenever i pull it out. i particular love the blank stares i get when i call it my primitive compound!!! the vital statistics on this bow(yes i know folk are probably waiting for this) 68" tip to tip,with the back bow runing 36" tip to tip. the primary bow is hickory backed hickory with a mulberry handle and hickory heartwood tip overlays. the back bow is hickory backed mulberry glued into a 1.5" reflex, and then tillered to 50lbs. at three inches. the limb tip overlays on the backbow are also mulberry.
