Let me just start by stating that I'm not intensionally trying to be argumentative in the statements below. I've been a member of Many Forums, for Many Years now and I know how online communication is and can be. So just understand that I'm simply trying to get a point across here.
Read on....
HONESTLY!!!! I see more potential in the cedar fence posts and wire we keep our cattle rounded up in. It really seems to me as if you are looking to find an off the shelf stock of wood you don't have to do much carving too. If that is the case, build a door frame wind turbine that will not work or a loud plastic blade turbine that looks cool and slows the wind going through the rotor or..... Buy some real blades already or build the right ones.
When I decided I had wasted enough time and money trying to save the money I'd been wasting looking for what everyone else has failed with, I bought what was suggested and began making progress. These guys know their stuff. Take their suggestions and make some power.
I promise you this, once you build, by hand, the turbine with the proper rotors- you will find out how the wind makes them turn and turn to make power. Then, you can progressively try new, to you, designs and material which you can make ( mold ) to your specific generator. Until you have made something work, you are going ask why not and how come and what for.... Good luck, now go make a few volts.
The only thing, taking into consideration that it would be a hardwood casing and sanded to proper specs (because there is Technically no other difference as Oak is Oak, Cherry is Cherry, as Long as the grain runs the length of the Blade), Is that the angle of approach of the blade once sanded would have to prepared with another piece of wood with the same grain direction properly cure to the end of the blade that attaches to the rotor. This would be the only thing that would Might prove to be challenging..
You have to be able to see my point here.. It is possible. Still dont' know if I would do it. but it was merely an observation. And if one doesn't have the tools to start from scratch on a carving a set of blades for a rotor, then why not start, if able, with somethig a little further along in the process?
My best answer would be an unenthusiastic "maybe?". Well since you already bought the raptor blades how about whipping up some PVC blades and testing the differences, not being a smartass, I really would like to know 
I'm on my first wind turbine build, its just a small treadmill motor job, for the same amount of work I could be building a larger unit, but I am learning a lot, and it will make the larger build easier.

So in essence, you honestly don't have much say in the area? No Offense of course. if you are in the middle of your first build as well, we are in the same frame of reference, psychiologically.
P.S. Why so unenthusiastic? Enthusiasm is the very epitome of scientific advances...
I don't even remember the amount of these threads where a newbie comes along and wants to build a turbine from junk yard parts and some kind of funky blades, then when it's done wants to know "what's wrong with my DMM"? LOL.
I don't remember stating that I've purchased anything from a junkyard, Fab? So why deos it have to be "Carved out Wooden Blades" that are the golden child here.... Out of all of the threads that I've read, I don't think that one person has technically given the reason for the popularity of the Carved Wooden Blades on this site, Other than to prove that you can do it. Or that you are willing to take everyone's word that you "Should" make a set...
Can someone explain what the reason is for needing Carved Woodedn Blades to successfully produce a Decent Windmill that produces acceptable power?
Maybe it's becasue of the weight of them? Or the pride is saying that you careved them yourself? Thanks in advance!
Listen, I can understand everyone's points here.
