Sorry, I need to vent.
I usually buy my hardwoods and plywoods at a large lumber yard. The large yards (Spellman Hardwoods and American Hardwoods) have great quality for american hardwoods and plywoods, but they are 30 - 60 minutes away and only open for business hours. Unfortunately sometimes I need "just one more piece" to finish a project. There are a couple of "retail" wood stores in my area. One, Woodworkers Source, has tons of exotic hardwoods, and a good selection of plywoods. But, there are two huge issues in dealing with them.
1) The plywoods and american hardwoods are of very low quality. The wood isn't very dry, it's not straight, and there are lots of splits and cracks. Seriously, this stuff might be the material commercial shops return to their suppliers. I don't know where they get such bad material. The plywood warps badly within a day or two, must be wet as well.
2) Woodworkers Source rounds up when measuring the hardwood. Let me explain. When I buy 100 bd ft or more at one of the large hardwood yards. They take a "stick" (special ruler for measuring hardwood that has a table printed on it to show bd ft by width and length). They find the narrowest part of the board, and measure the width there. Then they take the nominal lenth, and use the scale on the "stick" to find the bd ft. By nominal length, I mean say a board is supposed to be 8 ft long. Usually it's cut a little long at the mill, maybe 100" instead of 96", but the large hardood yards call it 8 ft. Woodworkers Source measures the widest part of the board, and rounds up to the next highest 1/4", and then they measure the length at the longest part of the board and round up to the next highest 1/4". Since the quality is so low the ends are usually split for the first 3-4" in on each end. Their lumber is not S4S, so the sides are rough, not straight, and there are usually splits there too. On top of all this, they charge 50-70% more per bd ft than the large yards. If the wood were top quality stuff, paying a huge markup and the 5% or so extra for their rounding up would be ok.
I can't imagine how frustrating it must be for new woodworkers who don't know better.
I recently found a small private hardwood yard about 20 minutes away. really nice guy, really nice stock, and his prices are the same as the big yards. This place is Chandler Hardwoods near the Chandler Airport in Chandler AZ. Highly recommended. I just bough two pieces of maple from them. By my measuring, it should have been about 21 bd ft. They charges me for 18. If I measured the way Woodworkers Source does, it would have been 25 bd ft. The price per bd ft was less than 1/2 of what Woodworkers Source charges.
If you are buying at Woodworkers Source, take a drive over to this other yard and see what you have been missing.
