Heard of acx plywood?

[kmk]

What is it? I found them on craigslist for $20 a sheet (4x8). Good for building
cabinets (shop use)?

Well, I'm sure someone will correct me if I'm wrong. But I believe ACX means one good face (though may be plugged), one "bad" face (unplugged), and Xterior (marine-grade) glue.

If that quality is good (not too warped or too voidy), and it is 3/4" or 5/8" plywood, I think it would make fine shop cabinets.

Agreed, I'd call it G1S-ext - good one side with exterior grade glue. Doesn't sound like a great deal though does it?

that's what i thought first, one side A (clear), one side C (knots and voids) and exterior grade (waterproof glue, for use outdoors or exposed to some water). Not necessarily marine grade though?

We use it for replacement floors etc in boats but give it a coat of fiberglass resin prior to installing.
The price sounds good as the last sheet of 3/4" that I picked up was around $40.00.

as mentioned, it's A grade (clear) one side, C grade the other side (footballs). I don't think the X means exterior, it certainly doesn't mean marine grade.

ACX and CDX are regular common plywood you find at HD and Lowes

If one side is going to bad, I guess I can't use to build cabinets. $20 for 4x8 sheet plywood sounded great! I've bought plywood (birch) before but mostly misc sizes from Rockler or Woodcraft.

I need at least 1 - 4x8 sheet now to make some cabinets. I checked HD. They have 3 kinds. 3/4" birch - $35. 3/4" Oak - $48. And cabinet grade plywood - $25. What is the difference between cabinet grade and the rest particularly birch?

And, I checked the price at one of the local lumber store (woodcrafters). They quoted $69 for birch! Almost twice the cost of same sheet from HD. Any difference in quality?

Not necessarily marine grade though?

I think the glue is the same. But I think marine plywood actually is void free and has two finished sides. But I think exterior plywood and marine plywood use the same waterproof glue.

[HarmsWay]

You get different plywood than we do, but the ACX stuff you're talking about is probably softwood plywood. The glue may be the same as marine plywood, but the wood here would be spruce/pine/fir. When I think of marine ply I think of something like mahogany or teak that can be used in a marine application. Your cabinet grade ply at HD is probably someting such as poplar.

I did a search, and here's the wikipedia page for plywood http://en.wikipedia.org/wiki/Plywood

According to that page, the x is for exterior glue. Of course, wikipedia's accuracy may vary. But this seems to be what I remember reading somewhere before.

It should be usable for shop cabinets, but the C side could have voids that may or may not be filled. There may be voids in the core too.
