The most common material is MDF. There are other options, but they are a bit more expensive. I use a lightweight MDF called Trupan. 13 ply Baltic Birch is also supposed to be pretty good. Do NOT use oak plywood. The standard veneer core plywoods are not near dense enough.
For a tad extra my Home depot has MDF in 2X4 sheets. Perfect for those smaller boxes and those without a truck to get the full sheet home. At all costs avoid the geek on the saw. Use him for rough cuts if you have to and clean them up at home.
or u just scratch off the barcode n' take 3 sheets. go to the guy who cuts it n' have him cut it then walk out of the store. or you can not be a dick like this guy^^^ n' buy it
"Do NOT use oak plywood. The standard veneer core plywoods are not near dense enough."
Fisher I strongly disagree with you on that. Oak plywood is extremely strong and bearly even flexes. It's ALOT stronger than MDF ever thought about being.
Damnit Nick... how many times do I have to tell you that you don't have oak plywood but rather regular plywood with a thin oak veneer on the "finish" side?
No nick, oak ply is NOT stronger than MDF. Brad is correct. It just has a very thin piece of veneer on it. Oak ply is no different than maple, cherry, or any other vener ply.
If its just your basic 7 ply plywood, it has a very low grade core with many voids. Now, they make an MDF Oak, which is essentially mdf with an oak veneer. That stuff would be fine to use. But just your basic oak ply is a no-no. There is a reason you dont see anyone using it ;)
You pay $192 for a 4 x 8 sheet of oak ply? Your not using regular oak plywood. We sell it for around $50 per sheet. Material choice isnt necessarily based on strength. Its based on density. The more dense, the less chance of flex.
