Building A Self Bow From Scratch
A bow is just a piece of wood that stores energy when bent and releases it. That's the whole concept. The execution is where people waste weeks or destroy good hornbeam because they didn't understand grain alignment. I made my first bow from a piece of green hickory ten years ago. It worked, barely. The second one shot arrows consistently. Here's what actually matters. You need a straight-grained board, ideally quarter-sawn, about three feet long and four inches wide. thickness should start around three-quarter inch and taper toward the tips. The wood choice determines everything before you even pick up a knife. Hickory, osage orange, and yew are standard. I use hornbeam now because it's dense and behaves predictably, but it's harder to work with. Cherry works fine for light bows under thirty pounds but won't hold tension long-term. Draw your plan on the stave first. A classic D-shaped cross-section works for most beginners. The back of the bow, the side facing away from you when drawn, should remain untouched bark if possible, or at least undisturbed earlywood. That's the tension side. The belly, facing you, gets carved down. Flatten the belly gradually, working from center toward the tips. Leave about an inch uncarved at each tip for string attachment. Check your flex frequently by hand-drawing against a knee or a borrowed draw board. The bow should bend in a smooth curve, not kink at one spot. If it kinks, you've removed too much wood there. Shave less from the belly or add material to the back with epoxy and wood dust.
I learned this the hard way on a yew bow I spent six weeks shaping. It had a strongspot right at the nock area where the tiller refused to bend evenly. I spent another three days carefully shaving adjacent sections, not the problem spot itself, which is the counter-intuitive part. You don't fix a strongspot by removing more wood from the strongspot. You remove wood from the sections immediately next to it until the bend distributes properly. Took me a failed bow to understand that. Once the tiller looks even, sand the belly smooth and apply linseed oil. Ten coats minimum. Let it dry between each. The string comes last. Use polyester Dacron if you're pulling under sixty pounds. Fastflight works but degrades yew and other wooden backs faster. Tie a bowline loop on one end, secure with a fig jam knot on the other. Nocking points are two inches apart for most setups. Mark them with waxed thread wrapped tightly and a dab of superglue. The draw weight depends entirely on your wood choice and how far you taper it. A thirty-inch hickory stave at half-inch center thickness will pull roughly thirty-five to forty pounds at twenty-eight inch draw. Measure it with a spring scale if you want accuracy. Shoot it cautiously for the first five draws. Watch for any white stress lines on the back. Those mean the wood is failing. Kill the project there. It's cheaper than flying a bow when full draw.
