Limb thickness

[mzombek]

Hello guys,
I recently started a bow that I purchased materials from Bingham projects. I ordered 47#@28", 68" longbow. After laminating and cutting the knocks, I checked the wt. It turned out 67# @28". I always rely on Bingham for the proper thicknes of lams. After speaking with Elmont, he looked into my order and said what was needed for my bow was sent. I need to check them myself from now on.
I narrowed my limbs and can only get to 60#.
Can I measure the limbs laminated and get an accurate thicknes to compare to the charts of what I should have received?
I think that the bow is scrap, but will keep on working on it.
Thanks,
Z

did you make the riser longer or cut it less than 68"?---got pictures?

Im not sure about measuring, although im sure it would work fine, but dont, chalk the bow up to just scrap, find a friend or someone who shoots 60#, it would be a waste of a good bow.

You should be able to measure the thickness after the fades. I am not sure if the bow you built has tapers in it or all parallels? If you have a caliper (digital or dial) measure 10 or 12 inches from center of bow and get your thickness there, then you can add taper thickness back to center of bow. Looking at the Binghams weight chart, the 68" one piece straight limb longbow  takes a .380 total stack height for a 47 @ 28" longbow..It also looks like it takes .003 to make 1 # of draw weight. A .418 stack makes a 60# bow..

You probably still have a usable bow and may be able to reduce the weight -- how wide is your bow at the nocks and at the riser fades? My guess is you still have room to narrow at both places and remove quite a bit of material and then round over the edges- pretty easy to drop the weight you are at now.

I agree with Trux..I bet you can get it to 47#...

How wide is it at the fades?
How wide at the tips?
Did you trap it all at yet?
and one more, did you do a straight line taper from fade to tips or did you use bingham's arced taper format?

How narrow could he go?
