Here are few longbows I made recently. The adult ones are 1 1/4" wide at the handle with heavily rounded 5/8 ratio limbs. They are a bit whip tiller made, since they are long and not that strong.
1. Some tropic wood (Fava Amargosa) backed with maple 2mm thick, #38@28", 73" ntn. I tried this wood from curiosity. It is quite heavy, but does not handle compression well. It likes to raise a splinter, so I backed it. The curve is nice, bow has a mild kick but cannot be used for higher poundage at this design, as it got 2" set at low pounds and serious length. I keep it because it looks nice.
2. Maple longbow named "Mary Rose", 70" long #50 @ 28". Stained with oak color oil stain, shellac and sprayed alkyd lacquer. It has some 1.5" set after unbracing, quite good for the 5/8 design and no heat treatment. Epoxy putty nocks.
3. European oak longbow "The Black Prince", 72" long, #49@28". Stained with palisander oil stain, shellac and lacquer. Epoxy putty nocks. Set is barely 1".
4. European oak longbow for my daughter, 63" long, some #30@24", 1.1" wide. Stained dark as above. Epoxy putty nocks.
