Before Wade purchased the rights to the American Watch Tool Company's larger Bench Lathes in 1918 they were already making a backgeared and screwcutting lathe - the 8.5" x 24" Toolmaker's Model 8A. This was a beautiful machine, equal to Rivett's 8-inch Precision and 608 models for attention to detail and quality of fit and finish and an advance in terms of rigidity and capacity for rapid metal removal. Advertised as: "The ultimate in lathes for close precision work within its capacity" it had a swing of 8.5" (a centre height of 4.25") and iadmitted 24" between centres. For an 8" lathe the hardened and ground spindle was truly massive: it had a clear hole of 11/4" (later given as 13/16" in the sales literature) a generously-sized nose with a thread of 2" x 10 t.p.i. and was able to accept "Wade No. 8" collets with a maximum through bore of 1". Early versions employed traditional Wade plain hardened, ground and lapped steel bearings of the "watchmaker-lathe" type but later machines, from an indeterminate date sometime in the early 1930s, were fitted with what were called, in contemporary literature, "anti-friction" bearings; that immediately behind the spindle thread was a double-row roller bearing and, just back from that (and also contained within the front housing), was a precision ball thrust bearing; the rear of the spindle was supported in a deep-groove ball bearing. The bearings were set under a slight preload, to ensure that the spindle was held as rigidly as possible. On these lathes, when backgear was engaged, the cone pulley ran on its own long roller bearing. Both headstock and tailstock (the former with a short reduction sleeve) were fitted with No. 2 Morse taper centres. Another wade Precision Bench Lathe, the No. 8, was listed alongside the 8A for a time but, upon the introduction of lathes made by the Watch Tool Company, this model was dropped and only the fully-equipped 8A shown in the advertising literature. The customer for the 8A was given the choice of either a hardened and ground bed - or one which was left in its natural state then hand-scraped and "spotted". Originally available just for bench mounting, later machines were fitted to oak and then, post WW2, much stronger steel cabinet stands. The drive systems varied according to the times with first a traditional overhead countershaft unit (though beautifully constructed on cast-iron uprights) and then with the option of a neat, under-drive stand that still employed a flat-belt drive but, like the Schaublin 102, offered a belt-shifting mechanism that allowed speeds to be swapped without stopping the motor. In the 1950s, in an effort to modernise the lathe, it was offered with a mechanical infinitely-variable-speed drive of the type that used a wide "V-belt" and expanding and contracting pulleys (controlled by a wheel on the front face of the stand marked "slow" and "fast"); because there were no belt positions to indicate the spindle speed this model was fitted with a rather fine-looking but rather large electric tachometer on the front face of the headstock. Most lathes offered by the factory fitted to self-contained benches had 2-speed 3-phase motors that, in combination with backgear, gave a total of 12 spindle speeds. A later development was the fitting of a motor at the tailstock end of the bed that provided a variable-speed electrical drive to the power sliding and surfacing feed - so rivalling, for a time, the facilities offered on a Hardinge HLV lathe.
