Default Bow warping



Advertise Here

I got a nice length of yew, and made a self-bow with it. It was 6'6" long, then I started to tiller it. The line of the string seemed off, which was strange after the time I had spent on the stave.

Now (three days later) it's got a 2" curve in it, left to right. It's bizarre. Is there any way I can straighten it, and if so, what kit do I need?

I have absolutely no experience in this, so take this with a grain of salt and research it. However, I once saw someone soak their bow in water for a few hours and then they heated it, which made it pliable. When in it's pliable state, you can do anything you want to it. Once you return it to the original shape, you have to let it completely dry in that shape, or you stand the chance of it warping again (no moisture in the wood fiber). Also, consider the fact that it probably warped for a reason. Bad cut against the grain? Too thin of material? You may want to consider using shaped plastic to prevent warping or curling. This is a standard practice with many wood products that are made. Did you happen to varnish or seal the wood while there was still moisture in it?

For commercial recurves, I've taken twists out by lying the bow over the kitchen sink and running hot water over the twist for a few minutes, then physically twisting it back to straighten the bow, holding it until it cools. I've had to repeat the process a few times to get it truly straight. It works on fiberglass laminates, but I don't know if it would work on your yew longbow. Good luck.

I wrapped it in cloth, clamped it straight then poured boiling water over it, a number of times. I left it in the clamps for 48 hours. It's now perfectly straight again! I will leave it another month to dry properly, then try again with the tillering and shaping.

Glad the hot water trick worked out for you, brother.

If you're planning on building many more a steam box can be built without much trouble or money and may be worth the effort. Hot water will work too but the steam box allows you to drastically alter the grain. Steam it, get it in the clamps quick and wait. You can get a nice reflex/deflex in a self bow this way. Hickory and Osage will take and hold a set as well as any wood I've worked with. Mulberry is nice too but it's a bit more tedious to work with a draw knife. Glad to hear the hot water got you out of a bind. I know what it's like to have a lot of time in a bow and make a bad gouge or overcut a nock or shelf!

+1 on the steam/sweat box. not that expensive or hard to make, and work wonders on bowed/twisted wood. used to watch a friend bend ribs for canoe's he built.

Just to follow up, this stick is now a 20 pound bow, nice and straight, which is useful for warm-ups and grouping before I switch to a heavier bow. It always attracts comments at the range, because no-one else seems to use longbows, or any kit they made for themselves.
