Thank you for your service Sir.
You stated "If all goes well",,, two staves @ 2 1/2" at the top (bark) or at your chosen ring???? You'll loose some width when splitting as the wood can tear rather than break apart like a short peice of firewood does. A bandsaw would reduce that loss somewhat.... Scoring a line in the whitewood before splitting might help insure two staves? Removing the whitewood is good advice in this case as well....
I like to clamp my staves down about at the height of my solorplex. Arms sretched out but not locked in. I use my legs (at about a one step stance forward)and my body weight to draw the knife; rather than using my arm strength. The arms just keep me where I want to be on the blade angle and kilter.
If the stave is cured well,,,,, wait till you hit the hardwood!!!!
That is why I'll say this,,, and admit I have only read one selfbow book....
Don't put too much thinking in to taking off the whitewood. I go at it like the house is on fire! Bark first then the whitewood. Your chosen ring is pretty deep, so hitting into a ring or three while removing the bark and whitewood wont get you in trouble. To me the trick is; dont try and take too deep of a bite. This tears off more wood (sometimes) than you need and can tear into your chosen ring. Do more slicing than tearing once you get to seeing the yellerwood! From there, you'll have a few rings you can practice on.
I can't wait to see more!!!!
