I harvested the wheat with a scythe (sp), and did my best to keep the heads all in the same direction.  From there I set out a tarp and placed a portion of the wheat on the tarp.  I used a large leaf rake and beat the wheat until the heads were mostly detached from the stalks.  At that point I continue to beat the heads while removing the chalf (sp).  Eventually I hand rub the wheat heads until the seeds drop from them.  From there I toss the remaining seed and chalf over the tarp during a light breeze until I have almost nothing but seed available.
So far I have spent a couple of hours doing the threshing and have about 7lbs of seed.  I estimate that i have about another 30lbs of seed to still be removed.  
I am guessing (and hoping) that as I learn how to be more efficient at this, I will be able to get through this process much more quickly.  It reminds me alot of gold panning - you just keep working the payload down until there is nothing left but the gold.
Any suggestions here would be greatly appreciated!
