I've never done this combo before but had a teacher asked about making a bow...we glued the stack into a very mild r/d which will likely end up flat. It is barely 1 1/2" wide and 1/2" thick...not quite 66" total length. We cut a stack of 12" hickory/walnut lams and stacked them for the riser/grip... I'm hoping for a 64" n-t-n bow that will be a good 45# since he has never shot a longbow. Any layout suggestions would be appreciated.

I think 45# might be a bit much at 28" for only 1.5" wide. Id keep it full width to mid limb then taper to 1/2" mocks.
I might shoot for 40# but that's just my take. Hickory should spray together either way but it'll take more set at 45#. I think at that length and width a 40# bow will shoot faster at 10gpp than a 45# bow at 10gpp. I have no actual facts to back that up just a feeling. Also a 40# bow will kill a deer and will be easier to shoot.
Get us some pics as it comes along!
If its not too late Bob, Id keep that width to at least mid limb, or where your reflex takes off. 1 1/2" is a tad narrow, but its a tri lam with glue between layers, that's stuff is mean!
that's what I did...I posted pics on a couple of sites but it's harder to do here... I used TB3 for the first time so I'm letting it dry a couple of weeks.
thanks.
Bob
If you haven't done the glue-up yet heat temper the hickory belly lam to increase the compression strength. Hickory isn't all that strong in compression.
I already did the glue up Pat... I will remember it next time though...I am assuming that it's too late to do since I glued it with TB3..?
thanks!
Bob
Yes, it is too late. TB glues release at 150deg and tempering will get it that hot at least.
oh well...good to know on the next one... :^)
thanks and Merry Christmas!
BTW- I'm more of a sinew backed osage guy...like your last bow...
