Too much to be exact, but its in tree form, i had some Juniper tree sections but my father cut them in pieces that was under 2 foot and we burnt them long ago LOL, im thinking about making some Medieval arrows, if i can get some fresh feathers make soem flu flu styles and just use some trade points when im at the cabin this summer, just need to find the metal, might buy some sets of spoons they have some in the stores 5 for 3 dollars, i dont want to use dowels, although they are oak i shaved one down, it was the only piece of birch that i have seen in the shed, it is around 48 inches and no knots LOL, im going to look of a piece of birch that had the least amount of knots ans make a little self bow, any advise on making a bow if the wood has knots?? ive just made survival bows and out of pieces of trees that were 3 inches around, cut the nocks and a small shelf and it lasted a few months
