Ahhh the long standing argument of woodworkers...
The ones who use power tools claim they are faster, while the hand cut dovetailers claim they are faster. In my opinion, go with hand cut dovetails. Everyone asks "oh are those hand cut dovetails" and its true pride to show them the over-cut marks (as inevitably they are some) and say yes they are. I also think they are faster and easier to do then fiddling with the machines.
By the way Ken, have you ever tried Lovetails? I think they are easier to make then dovetails. I am not making that up. They only look hard to make. I also think they look really cool!!
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
