Ammco Rockwell Delta 7 Metal Shaper. Metal Shaper is in excellent looking condition. It was running when removed from the watchmakers shop. This is a great little shaper that I’ve owned for many years. It runs great and everything is in great condition. The stock light is also there (but needs to be wired). By the time shapers get down to below a 7 stroke they usually come to resemble something. Other than a standard industrial machine. But not so the American “Ammco”. 2112 Commonwealth Avenue, North Chicago, was constructed exactly along the lines of larger machines and had five rates of reversible automatic cross feed – though the feed dial was ungraduated and there was no slide lock. The box had a horizontal travel of 9.5″, vertically 4.25″ and could be moved to within 1.125 inches of the ram or extended to be some 5.25 inches away. The toolholder had a maximum travel of 3.25 inches. A useful safety feature was that the box would run off its feed screw if left on self-act – because shaper work is so steady there is a terrible temptation to set, and forget.. Four speeds were provided of 40, 70, 115 and 180 strokes per minute, from a rear-mounted motor which drove to a large pulley – the supporting shaft of which passed through the rear of the body casting and carried at its other end a four-step pulley to drive the crank. Each of the two drive belts were arranged so that they could be independently adjustable for tension. The box was properly supported at its front by a bar able to slide along a machined base and a most useful looking vice, with 4″ wide jaws and an open capacity of 4.25″, was supplied as standard. Unfortunately, the slots in the table were not of T section, but had plain, parallel sides. In the base of each slot was a row of plain 5/16 holes – which enterprising owners were able to tap out and use to bolt workpieces and attachments in place. Both early and late versions have been discovered, the earlier having what might just be a unique method of turning the table-feed ratchet on a shaper – a cable. While the late version had its electric motor foot-mounted onto the rear of the main body and drive by V-belts, the first version had a 3-step flat-belt cone pulley on the input shaft – this obviously being intended for drive by either overhead line shafting in a workshop or by a remote countershaft. The original shaper was supplied by the makers on a fine maple cabinet stand with cupboard and drawer storage – and, as two identical specimens of the stand have come to light, this disproves the theory that the first might have been a home-made affair. Although claimed as a 6-inch machine by Ammco in their sales literature, the maximum stroke was actually 7.25 with Delta Rockwell themselves advertising it as a 7-inch. The shaper is 32″ long, 18″ wide, 242 high and weighed 225 lbs. The item “Ammco Rockwell Delta 7 Metal Shaper” is in sale since Tuesday, February 25, 2020.
