Western Aircraft Tool Co.
"New-All" Lathe Screwcutting
& Feeds Gearbox
Offered during the mid 1940s, unfortunately just before the genuine maker's screwcutting gearbox became available for Atlas lathes in 1947, the Western Aircraft Tool Company's "New-All" unit was attached by drilling and tapping four holes in the bed. Exactly when production started is uncertain, but in November 1945 advertisements appeared proclaiming: "New improved model!" - which, assuming this to be true (and such publicity "puffs" rarely were), might put the start some twelve months earlier. Early literature mentions a gearbox casing in aluminium, but later ones were in cast iron--with both types using bronze bushes for the shafts.
At first, in addition to 10-inch Atlas lathes (and their Craftsman copies), the box could also be supplied to fit machines from Logan and Powerkraft and later, by mid 1946, South Bend 9-inch lathes as well. At this point the unit was being offered at $75 - in comparison, a complete Craftsman 12-inch gearbox conversion set had been $125 in 1943 rising to $197 during 1947 (the latter being the first post-war WW2 year in which the lathes became available). By April, 1947, when the final advertisements appeared, the price had risen to $89.
If you have one these gearboxes, the writer would be interested to hear from you.
