glass thickness

[anchorman]

Was wondering if you increased the thickness of your laminations by .010 to compensate for using .010 thinner glass if it would change the way your bow shoots or draws. I know what I need as far as thickness goes using .040 glass but I am out of it and was wondering about the lamination thickness.

From my experience thickness of glass and wood work to a different scale. On mine approx .003 wood = 1#, and glass some where around .001 per #. hope this helps.Of course this depends on taper rates, amount of parallels etc.

Bob is right.  You will need to increase your wood stack disproportionately when decreasing glass thickness

In the last two straight limbed longbows that I made for myself I used a total stack of 0.440 with 0.050 glass and a total stack of 0.460 with 0.040 glass.  The one with 0.050 glass ended up heavier (63#) compared to the one with 0.040 glass (54#) even though the total stack for with the 0.040 glass was greater.

As far as shooting/drawing, I can't tell any difference. (I like 'em both.)
