Does the laminations, (glue, wood, fiberglass) on a new bow relax or change in someway, that after a hundred or so arrows the draw weight drops by a pound and settles?

They shouldn't no. But it MIGHT depend on design. Lots of wood to glass ratio could potentially develop string follow.

Lots of glass to wood could theoretically crush the belly causing string follow.

With a scenario would have to chabge the brace height.

Maybe not as drastic as a pound. But maybe as material is exercised it changes slightly?

If you are talking about changes that that ~1% in weight - do you honestly think many people actually know either way?

You would have to be performing exacting and controlled tests. And it would be hard to separate the results on the bow from the string.

I think your asking a question that almost no one has tested thoroughly if they are honest.

The question to me is what are you experiencing that makes you raise the question?

In my opinion it would be the wood items that would compress or change with moisture. Not very much either. Sometimes soft laminations such as yew can compress around the end of a wedge.

Most of us don't have equipment that measures that precisely. I suspect your brace height dropped a bit.

Possibly glue creep.

I'm gonna withdraw the question, as was said, it's impossible to get a consistent measurement when doing it by hand. Thanks for the input though.
