Actually, what is the claimed speed range of the 5914? This must have
been published in a brochure or catalog page somewhere. The scale on
the variable speed control wheel appears to be wider than the actual
range. For one thing, the scale goes to 2000 rpm, but one hits a
mechanical stop at 1900 rpm. Probably the same control wheel assembly
was used on multiple lathe models, each with slightly different
gear/pulley ratios, with limit stops adjusted to match.

Clausing claimed 52-280 rpm in back gear and 360-2000 in direct drive for
the 5900-series lathes. This from a Clausing brochure I have of unknown
vintage.

That agrees with the scales on the control wheel, but there is a hard
stop at 1900 rpm. Thus my question.
