I am always on the lookout for boring machines and have yet to see one like that, beautiful! It appears to be geared for higher speed and less torque. It might just be the picture but the driven miter gear looks to be smaller than the driver, any how it looks great let us know how well it works. I really like the idea of not getting off the timber to move the boring bit up or down the mortise.
