Tony,
The wood that I have is flatsawn Mahogany (Honduras). The boards are long and wide. They flat saw them to yield as much wood as they can get from the log, They make more money that way. Not all of it is suitable to use for laminated necks, but a lot of it is. I also have several 3 1/2 by 3 1/2 planks that I had intended to use on a piece of furniture many years ago. A couple of those will also work for a neck or two. I don't know where MRS got the picture, but it does not accurately depict the method a sawyer uses to cut quartersawn lumber.
I would guess that the Lutherie suppliers have to beg and plead in order to get quartersawn lumber. Quartersawing is wastefull and you don't usually get very wide pieces. SOme of the tonewood suppliers buy the billets and saw it themselves. But they probably pay dearly for them. I think we will see a decline in the exotic tonewoods in the near future. There is a lot of pressure being put on the industry to stop cutting down the trees in the rain forrests. As little wood as we use, it still has an effect on the ecosystems in the rainforrests. Buy it while you can.................That is why alternative neck woods is a good idea. While Luthiers may only use a small percentage of the woods, the furniture industry is the main user. And a lot of boats are made from mahogany, etc. I have been stockpiling tonewoods for this reason. The Zootman has made a bunch off me in the last year or so.

Actually i don't believe anyone here thinks they actually slice a log up as the picture show except maybe you. That would be plain stupid. What the pic shows is the description of rift. quarter and flatsawn. Thats all it is. A description. When they saw a log up most chose to do a flatsawn method to obtain the most usable lumber. If they chose to do quartersawn they would first cut the log into 4 pie shaped pieces then pass the qurtered pieces through the saw getting qurtersawn. There is a lot more waste involved so it is not a common thing. If you look at the diagram you can see how the middle of the log boards of flatsawn can pass for rift or quarted. This is where the majority of quartered wood comes from. technically rift sawn produces lumber with straighter grain the quartered but is much harder method to cut. This is why many by quartered billets and split them to get guitar tops and braces. They want the most straight grain they can get. This can also explain the higher prices because of the rarity of the cut and the difficulty obtaining it...Mike

Actually the image i posted is correct for rift and quartersawn. The second image is declaring the the middle board on the quartered side can be declared rift sawn and the middle board on the rift side can be declared quartered. Which is true as also is the seventh board on the flat can pass as quartered or rift sawn.

I guess that shows why "quarter sawn" can be up to 45% off vertical.

its a bit confusing that link as quarter sawn timber would cut into quarters and they would take one cut from one face and the turn the log round to get the next cut from the other face to get perfect virtal grain.
however every miller will use a variation on the term.

here is a better link to the taylor vids,

it shows how spruce is split in the second vid they go into sawing from split billits,

They wouldn't need to turn the log. They would have to flip the quartered section back and forth. More work to obtain something means higher prices for the product. This is why we pay more for quartered.Browse down in the link provided to the second photo and it will explain the method of quartersawing.
