Steam Bending and Titebond III?
« on: November 19, 2013, 12:32:00 PM »
Waiting a few weeks to get back to my ash project and the white oak log I need to split into staves, I decided to try and build a red oak board bow, for a few dollars investment I figured why not.  I am making it for my daughter so I cut it to 62" and glued up the handle piece.  Shaped it to dimension and glued up some silk backing.  My wife bought me a yard of black Dupioni and it is a little rough in texture compared to the stuff you find in fine clothing but it worked.  I waited a day and a half for it to dry and hit the backing a thin coat of spar urethane to keep it from fraying while I work things.  Then I noticed that a string from tip to tip runs about 1/8" off center of the handle/riser.  I figured if I steam it and clamp it up in a simple jig I could get it perfect but I am concerned it might loosen up my glue joints and backing. An eighth of an inch isn't that big of a deal so what say all of you?

Leave it as is, that's my vote. Id love to be within an 1/8" on any of my work.

I'm with Pearl.  If possible make the arrow pass on the side that the string tracks to.  Puts you an 1/8" closer to center shot.    :)
It's hard to make a wooden bow which isn't beautiful, even if it's ugly.

Thanks guys.  I will leave it be.  One thing I have noticed with the silk backing is that put on wet it shrinks up tight and though the stuff I used is not dress gown quality, it looks pretty good.  I will start tillering it in a few days and hopefully in a week or so I will have my first bow.  

This white oak log is intimidating me a bit.  I have to get at splitting it down some time, maybe this evening.  I noticed a couple checks in th eends.  I sealed them up with paint but it still checked a little.  The log is about 6 1/2 feet long so i should be ok.

you can use some mild dry heat with TBIII but I wouldn;t bother. If you're not careful it can result in disasterous delamination.

All TB glues will release at 150deg(F) so I wouldn't use any heat where it might affect the glue. You could however heat the whole bow to release the glue, make you repair, clean up the glue surfaces and re-glue it.
Make the most of all that comes and the least of all that goes!

I would just let her shoot it. You go messing with it and bad things could happen.
