She Who Must Be Obeyed has decided my next project is going to be making several mission style end tables with lots and lots of tenons and mortises. I have a very hard time doing these mortises with hand tools - just don't have the coordination for it.

I've seen photos of some of the various bench top mortisers but have not seen them in use or in person. I see that the drill portion cleans out the center and the chisel portion squares off the opening. How does the chisel get its thrust? Just the downward pressure from your arm? Is it really this simple?

Any recommendations for shall home shop use?
