if he stays with using borg wood, i would recommend he let's it dry out for 1-2 weeks in his garage and i would recommend he does extensive doweling of the joints. I was thinking of using titebond III for the glue up. Any other major things I could do to help his project if he sticks with borg wood?
Be sure you DO NOT use pressure treated.
SYP or DF are fine. They are in the store at max 19% MC. Letting them dry some more won't hurt, but at this time of year, I doubt they are at 19% anyway.
But - if you let them sit for a couple weeks, you will be prone to warp/twist. Me - I'd drop down to maybe 2 x 6. If you just joint the edges like any glue-up, the T-III will do fine.
When I started woodworking, I didn't know squat. I have progressed in 30 years - now I do know squat.
