Title: An odd occurrence
Post by: Joec123able on May 14, 2013, 09:46:16 pm
I have a bow of mine I hadn't had it strung for almost two months I decided to string it up today to find the tiller way off compared to how it was the last time it was strung I really can't think of any reason for it

Was it standing up on concrete? Was one end near a heat vent? Was it well seasoned when you made it? Even a kiln dried board that has been sitting for a few years will twist and contort  after you cut it and joint it. Every shaving you remove exposes fresh wood and new stresses, sometimes it's more dramatic than others.

It happens to me too sometimes.  In my case, wood dries very quickly and often unevenly in my climate.  I have learned to season the wood well before final tillering.

The bow was just hanging up on the wall I finished in back in January the wood is sealed up with lacquer and it's in room temperature I really don' get it

did some insects get it? did something grow on the wood? has the humidity changed at all? cause if it has, keep in mind that the varnish coat might be slightly uneven, and it wouldn't take much to throw it off cause of different moisture content.

Explain that to me? You lost me.

What kind of wood? Design? Don't let my next question insult you but are you sure it was absolutely seasoned after completion and maybe it dried some more in the last 2 months?
                       jackcraft may have nailed it about making sure you are completely seasoning your wood.

I think I'm with pearl. Unless the change where it was originally stored and sealed is significant it might take a little longer to equalize if one side is sealed better but equal is equal. They will both end up the same as their surrounding.  From what I hear, no seal is completely water/moisture proof.

And to the original poster, is it possible the sun hits part of the bow at some point in the day thru a window? I'm with the others. it sounds like something is heating it somehow or it wasn't seasoned enough. Or possibly elves. Were you drinking when it was strung last time?

That happens alot.  I think it's mainly a drying issue.  Maybe you didn't dry it long enough?  Humidity change?  Maybe the tiller was slightly off to begin with and it's dried more?

Ive made 150-175 bows from 8-9 types of wood and its never happened to me, sinewed bows included.

the only time that's ever happened to me  is when I quickly made a bow and did not exercise the limbs very much when building it  and did not shoot it in . but it usually falls out the tiller after I go and shoot it for a while . for me it's basically garbage in equals garbage out .

The Bow is Osage and it has shot well over 1500 arrows so trust me the limb are exercised

Well the uneven finish thing wouldn't make sence when it's be fine over the past 5 months

No drinking involved lol the bow is hit by the sun part of the day but I don't see that doing anything other then darkening the Osage wood

Well, that could in fact be your problem. Direct intense sunlight is bad for wooden bows, especially laminated bows. It's one of the first things I tell people that will void their warranty. I've had more than one person bring me their bow that has delaminated from leaving it in the direct sun, like inside a closed car. It will do more than darken the osage.

That all makes sence but this bow is just a selfbow and it will be seeing a lot of sunlight this summer when I shoot it lol

Self bow or not... shooting it in the sunlight and storing it in direct sunlight are two very different things.

Ok well I will avoid having it stored in the sun light even tho I love seeing the wood darken up thanks adb

Don't worry, your osage will darken plenty just having it outside while you're shooting it.
