Patrick,
The automatic slot mortisers, like the Bacci, Balestrini, Rye, Pade etc are all powered cross travel and variable feed speed. There is also no bit whip with these machines.
Bit whip occurs with the hand machines due to the table banging into a stop at each end of the cross stroke; these machines use a system like a piston and crank, where a rotary shaft drives a linear table, this gives a perfect ramp-down / ramp-up at the ends of each stroke, the change in direction of each stroke is incredible smooth and the stop is unperceivable.
Of course out of the factory they are designed for high production, speed over quality, but when properly tweaked for quality over speed
they simple cant be beat.
Matched with their counterpart tenoners are the dream team for chair making.
These are brilliant machines.
