ALRIGHTY! Now we're getting somewhere!
Painting the whole cabinet, deciding on pine, now look at how much of a difference there is between half and three quarters pine in that size, and we're now down to $5 for the good stuff, and if you move down a step, the difference is still the same, but now you're onto something that saves you money but is still suitable for painting! Look at the difference between the CDX sheet at
3/
4" versus the ACX sheet of
1/
2" and the difference is even less. NOW I'd say if you're gonna save your money and do everything in pine, skip the ACX grade and move one step down. It'll take a touch more to finish, but your time saves you money, right?
Since you're gonna paint this, check out my project thread and look at the skim coat of drywall compound I did on the CP top. It's on one of the later pages, so you don't have to read through that whole thing. That drywall compound will level everything out once you've sanded it smooth, and it'll fill in any imperfections like knotholes, those little footballs they might have, cracks, etc. If you don't do it, your grain will show through. It's a personal choice, so it's definitely not necessary, but it'll darn sure make a nice smooth finish compared to how plain plywood of ANY species will soak up paint differently. Save a few scraps and test it out and compare the two to see what I mean. They sell that DAP pre-mixed compound in little half-pint containers for only a buck or two.
I think you'll end up saving yourself a pile more money going with pine all the way through, and if you choose to go that route, why not go the whole nine yards and make the wood the same thickness all the way through to make measurements and whatnot a whole lot easier?
