Announced during 1936, and sold into the early 1940s, the Walker-Turner Driver Add-A-Tool was a combination woodworking machine and metal lathe. Based on a solid steel bar turned so that one edge faced upwards and with a swing of 7.5 inches and a between-centres capacity of 30 inches, it was offered as various units (listed A to K) that could, as funds allowed, be built up to include a saw-bench, planer, band-saw, jointer, a compound metal-turning rest and a flexible drive assembly. The whole apparatus was designed for mounting on a wooden-topped stand with a built-on 12-speed countershaft unit with the weight of the 1/3 h.p. motor providing tension to the V-belt drive. Speeds ranged from a low of 400 through 724, 765, 1225, 1345, 1420, 2150, 2275, 2440 3900, 4000 to an astonishingly fast 7400 r.p.m. To simplify matters, the flexible drive unit was used to power the band-saw and jointer, the drive being taken from tan extension to the countershaft. The No. 1 Morse taper headstock spindle, 3/4" in diameter, ran in plain bronze bearings and was fitted with a ball-bearing thrust race
For decoration, the bedways, front of the face of the saw-bench and even the whole length of the double-length wood-turning rest were given a mock hand-scraped appearance.
