This blueprint is from one of the early iterations of the "sylph" winnower that John Nanci over at Chocolate Alchemy designed. Have you asked on that forum?
BTW, you uploaded a very small thumbnail that's impossible to read.
I noticed you posted a question on a DIY seed cleaner winnower that I posted a while ago.
If you are looking to DIY something yourself, I recommend this "visible" design where you can see what's happening, take it apart, and tweak it. I posted some thoughts about how to improve the basic design for use with winnowing cocoa in the comments to the video.
I have made that winnower a year ago and it still works well. I assume you refer to the piece of pipe you'll need to cut out and use to create a kind of convection in the supply tube? You'll just put it in-side, place look at the photo's that are placed on the site where you got it from. The system works oke for small scale, a constant supply is crucial to obtain a oke efficiency (depends a lot on the cracking of the beans).
Hi Donny,As Clay mentioned, this was designed by John at Chocolate Alchemy. I started a thread over there about it when he first released the design that has a fair amount of discussion about its design and construction (although I'm not sure if your specific question is answered there yet): http://chocolatetalk.proboards.com/thread/975/chocolate-alchemy-diy...
John talks about the deflector disk in this blog entry:
There's a lot of great info in all of the blog entries and comments about the winnower:

I'm not sure what you mean by it being cut 3/4 of the way and bent. When you cut the hole in the pvc, you're left with a disk. That is then bolted to the inside of the pvc pipe blocking the bottom of the feeder pipe.
It's not bent (other than the existing curve of the disk). The drawing makes it look like the curve goes top-to-bottom, but really the curve fits into the curve of the pipe, as shown in the photo on that page.
Does that answer your question, or am I still misunderstanding?
No problem--glad to help!
