Just wanted to add to the sawmill disscusion
I think the prototype that is going is ok if you want the sawmill to generate a significant portion of your income while you farm or fabricate equipment, but there needs to be another more portable and manual model for the average homestead or community to use that is much simpler and user friendly. One that can integrate with the hydraulic power cube or tractor pto unit would be ideal. The most time and aggravation spent in converting logs to lumber is setting up and holding the log to be milled, that process could be done with the power cube to clamp (dog), taper and turn the log while a simple manually pushed, raised and lowered unit could do the cutting. That could be either band saw or circular saw / swing blade head and even a planer attachment like some manufacturers are making again.
Any one need help doing some drawing and design on this ? It sounds like you are on a time line but simplifying will help a lot.
