Power vs. Hand

As a follow-up to my post yesterday, I want to talk about why I could not earn a living with my woodworking, as I am currently set up.  When I first started purchasing tools, I only purchased hand tools, mainly because I could not afford or fit any power tools in my shop.  After a while I bought a bandsaw, a drill press, a grinder, and a router (all relatively small and inexpensive).  Why is this important?  Because about 80-90% of the time I have put in to this project so far has been milling.  Milling is making the wood the correct dimensions so I can cut joinery into it.  My current process it to use my bandsaw to rip the stock to the correct width, hand planing to flatten and square the faces, and hand sawing to cut the piece to length.  Almost every woodworker who makes money from making furniture has power tools to do almost all of these tasks, simply because milling by hand takes way too long.  If a task can be done more efficiently one way over another, it is unrealistic to do it the more inefficient way, and milling with power tools (using a jointer and planer) produce excellent results much quicker.  So to really start making money from woodworking, I would need to mechanize in order to reach maximum efficiency.
