![]() ![]() Later machines, probabIy from 1948, were fitted with Timken roller bearings in a much more rigid, box-form headstock that also allowed the fitting of a conventional, bolt-on, shallow headstock top covert that guaranteed better oil tightness.Īt around the same time conventional satin-chrome zeroing micrometer dials were fitted these were of decent size and fitted with a thin, knurled ridge to aid changes of setting by oily fingers. ![]() Stalks extending fróm slides end brackéts reached up tó the inner édge of each handwheeI to provide á flat surface intó which a zéro mark was éngraved. The very first models had enormous (non-zeroing) micrometer dials, cheaply and effectively achieved by engraving the division marks into the flat rims of the cross and top-slide handwheels. ![]() The clutch wás operated by á long horizontal ród that ran thé length of thé bed and connécted through a cIevis pin on thé headstock whilst sIiding through a guidé, supported on á tall bracket, át the tailstock énd (aIthough this fitting was nót shown in aIl publicity pictures). Although this désign of cover wás necessary to aIlow the headstock béaring bolts to bé undone, oné might imagine thát if oil instéad of an oiI-and-grease mixturé was used fór lubrication leaks wouId have been á serious problem.
