Thanks for the tips. Let me clarify I have rough cut stock anywher from 13” to 15” wide. The toy box is 12” deep meaning lid needs to be 13” wide for over hang. I initialy just though rip the 15” bosrds in half then straightening, glue up rip down to size. I dont have alot of room to rip multiple times losing an 1/8” each rip and then of course straightening outside edges of each board. Not so much worried about warping after glue up just disnt know how ripping, then straightening and flattening, would effect gluing back up at original rip if that makes sense
