I find plywood to be very stable unless it get's wet or damp they forget it.
I use alot of plywood for casework and hardwood for the face frames and the sides with panel inserts.
Most of the face frames are 2" to 3" wide and the glued up panels are 6" to 12" wide, they are one ones that give me fits, it's the glue that drives me nuts because it takes 2 weeks or more to dry out total just like a biscuit inserts ,moisture from the glue works out from the joint and I do use moisture meter, most of the time.
The woodworking channel had a small item on biscuit inserts that was real good he used his moisture meter and you could see that the biscuit would expand the wood and when you did the final sand it was done to the 220 grit, but into 2 weeks you now have a low spot that was the same size as the biscuit and would show up in the furniture....
The same thing on glue up joints....
Most of the glues I use are water base type for inside cabinets and I use the tiebond type for out side furniture.
So I found out if I use the wood as soon as I get it from the lumber yard (HomeDepot) it works best for me.
Cut it up and put it to work and the frame and case help hold it sq. unless it real bad from the get go.
Then they become short stock for the rails and stiles on the doors and to cover the plywood ends plus drawer guides ,inside case work,etc.
But I also drive a 1980 F250 4 x 4 Ford pickup hahahahahaha
that I got in 1980 and now has 156,000 miles on it and still running strong but it could be more because the speed O meter has not worked for 15 years or so hahahahahaha
but I don't need that dam thing anyway I drive slow most of the time
my last ticket was in 1998 for going 35 in 25 speed zone, you don't forget the tickets... hahahaha
Now when I get into my cherry red 1984 Vet. I do have a hvy.foot now and then.. hahahaha.
Have a good weekend bud
I guess it comes down to what works best for you and me.
