Hey guys as you see I am pretty new here and have only made a couple of bows. I am contemplating making my first laminate only made self bows and bamboo backed. Based off all the comments on here I would like to try the forward handle and will be ordering a kit from kennym. My question is this. Has anyone tried putting heavier glass on the back and lighter on the belly to get more snap or cast? I know I have to trap the backs of my bamboo backed bows but those are natural materials. Thanks. Hopefully it isn't a stupid question. Going to try a 58" longbow. I short bows.

I have heard heavier on belly, but I'm not sure I can tell any difference. My hunting bow has .05 on belly and .03 on back (test) but didn't gain much that I could tell from equal both sides. It's real hard to tell what gets a couple fps, two identical bows can be that different...

Wow I was surprised to see this old thread pop up, I haven't been around for a couple years do to taking care of a family member , but Kenny pretty much mirrored my experience with different backing thickness on this design , I started out with the standard size as it gave me a good base line to experiment from the shorter bows are a little harder to tiller and hit your weight and there is a pretty fair learning curve from self bows to glass so the easier I made it the better good luck and post you results !

From a structural standpoint this is the logical way to make the bow, but the experienced guys will tell you what these two just did and that it makes no measurable difference.

Thanks all. Just silly thoughts on my head

On an ASL I go a little thicker on the belly to defend against core compression and string follow. Sort of trying to center the neutral plane.
