label: Description
content: “The matter of friction in a foot machine of any description is of vital importance, and in the construction of this, as well as all our machines, we have studied to reduce it to the smallest degree. The heads of these lathes have solid conical bronze bearings, arranged for adjustment in case of wear. The spindle has a taper screw on the right-hand end for brush wheels, and the chuck that holds the same can be removed and an ordinary drill chuck attached at a small expense. The other end of spindle has collars that take any kind of wheel or lap. The spindle is 3 feet 6 inches from the floor, the top is 2 feet long by 9 inches high. By this improved motion we accumulate more speed than is possible by any other known foot power. We guarantee that 6500 or more revolutions can be obtained by these machines”
