Overview

The Ex-Cello-O weighed over 2400 lbs and found favour with many jobbing engineering shops who might otherwise have chosen the splendid but ubiquitous American Bridgeport. Three table sizes were available: 36", 42" and 48" with, respectively, travels of 25", 31" and 37"; the table cross travel was a useful 13" and the vertical 16". The table and knee ways were all hand scraped and fitted with tapered gib strips; the table was not fitted with power feed as standard, but an optional kit was available--for either factory or retro-fitting--which, using a 0.25 hp motor, provided 12 speeds in two settings: low range from 1 to 3 inches per minute and high range from 3 to 9.75 inches per minute. Interestingly, although the fitting of the power-feed conversion reduced the table travel by 3.75 inches, the unit was not mounted on the table itself - where its weight might have caused the table to be deflected at the extreme end of its travel - but was hung from the edge of the cross slide.
