This machine came from the Olin Winchester firearms factory here in New Haven Ct. and has seen its share of walnut (gunstocks). The "finger feed" system is designed to minimize the deflection or deformation of stock inherant with roller type power feeders. It consists of many spring loaded fingers on a continuous overhead track or "chain." Both infeed and outfeed beds are corrugated. This machine was sold by The William H. Field Co. of Boston.
I can't comment just yet on it's performance but welcome others feedback with this machine, powerfeed system or in general.

10 hp 3450 rpm belt drive to the cutterhead with 20,500 CPM!
1/2 hp "US Varidrive" feed drive unit
