One other thing that may or may not apply, is like Randy said on the lams actually being weaker on one edge(Zebra lumber is one that does it) is to check them by bending the lams individually with 2 fingers on each end to see if they twist. If they bend in a twisting arc, turn them opposite back and belly so the grain would be strong side on opposite sides of limb.
Stay sharp, Kenny.

Thx Kenny, always doing this already with the core lams.

Btw, anyone with an idea on how to glue lams from stripes, like actionboo?

Don't forget to sacrifice a chicken and drip the blood in a circle around your form and also hang some Garlic off of it on your next glue-up...    :)      ;)

I glued up some walnut/ maple actionwood with .004 tapers and put the walnut thick end to bow tips for a swap bow a few years ago. Thad said it was his fastest bow.

I made it in a 2" square block with ea40 and resawed  into lams.
Stay sharp, Kenny.

>006 is quite bit of difference. Might make a recurve turn wrong side out.  :scared:     :scared:

Kenny, hope i'm understanding you right:
You were glueing some lams up, think those most likely were edge grained?

Then you cut that block into lams, these lams are consisting of thin stripes now, but are flat grained then?

Actually, I think it is opposite of what you just said. Glue up flat grain and when you resaw , it will be turned to have edge in the lams.....
Stay sharp, Kenny.
