Wood lamination

[Toymaker]

I did a lot of driving today and had lots of time think about all kinds of stuff. One of the things I thought about was Quatersawn vs Flatwawn wood. They are basically 90 degrees from one another. Since quartersawn is best for backings I was thinking if a Flatsawn board is cut in half and glued together it would be wide enough for a backng. Then this new board could be sliced thin for multiple backers. This picture shows what I'm thinking. I was wondering if this would be strong enough. If I did this I would put the glue line dead center the length of the bow. If I did this would it work for a flat bow as well as an ELB? If this would work how about a trilamb setup with a dark wood pinstripe in the center?


Red is cut lines, purple is glue lines.

I use the same glue up for one piece risers.Haven't tried it for backing. Might try a brake test with a piece. If the glue line holds it could work

Might be a good way to control lateral warping depending on how you glue them up. Sawed out some belly blanks and found them the next day with at least a 1/2inch of sideways bend in them.  My bet is that the backing would work quite well so long as the grain doesn't run out at the glue line.

I sometimes build picture frames for my wife and found when I buy lumber I need to let it acclimatize to my shop for a while before I cut it. If I cut it right away it will always warp. If I give it a few weeks to hit equalebrium the boards I rip to make the frames stay relatively straight.
 I use fir and spruce for the frames but I think any lumber is the same.
  Also reaction wood comes into play when dealing with sawn lumber.
