In the process of gluing up a Tri-lam 2 maple with oak core. One of the maple lams is slightly thinner, should the thinner one be used for the back......or the belly..? I'am thinking Back. ???
-
The thinner lam would be best on the back, yes.
-
Do you have access to a better, more compression strong belly wood?
-
There ain't nothing wrong with maple for a belly ;)
Trap the back and the belly will hold up just fine.
Thinner for the back yes.
-
Yes, use the thinner lam for the backing.
What thickness are the three lams each? You need to be careful to not scrape off the majority of the belly lam during tillering. Personally, I use a backing and core that are both about 1/8" thick and a belly lam that is at least twice that thickness.

What type of bow are you planning to make? ELB? Flatbow?
-
Yes, a thicker piece on the belly will allow material for removal while tillering or reducing weight wihout going through to the glue line.

R/D bow.......using maple for both. Last maple R/D was only 2 lams with cloth backing, but seems ok, just want to do a tri-lam easier to get the reflex in.
Yes, use the thinner lam for the backing.

Core is 1/8" Belly lam is not quite double thickness. I'am thinking it should be ok for a shorter bow around 64-62 @ 45#
