Unknown Lathes No. 61
Unknown Lathes Home Page

Now identified as a lathe designed by Mr. B.H.Fogg and intended for home construction, it was described in the Model Engineer Magazine for 9th  March, 1922. Obviously inspired by the Round-bed Drummond, this was a well-specified machine with backgear and screwcutting using 20 D.P. changewheels.  With an overall length of 29 inches (740 mm), its 155/16"-long bed had a diameter of just over 2 inches (54 mm), the centre height was 3.125" (78 mm) and it could take around 13" (330 mm) between centres. The backgear assembly was obviously designed as an extra-cost add-on, the rear gears being carried on an eccentric shaft held in bronze arms that bolt to flat surfaces machined on the back of the headstock casting.
Carried on top of the 75 mm x 190 mm asymmetric saddle was a 103 mm by 129 mm T-slotted boring table - the slots being created by bolt on strips rather than being machined into a casting. Unfortunately both the original cross-slide screw handwheel and top slide are missing - the latter, judging by the rest of the specification, would almost certainly have been supplied as part of the standard equipment. The original design for the carriage included a proper compound slide rest assembly with the top-slide swivelling about a vertical post - and it is suspected that the builder would have followed the original plans but have constructed the table as an accessory (there seems little point making something as limiting as a table that required an abnormally tall lantern tool post). 
Designed with an asymmetric profile (to allow it to pass the tool-holding top slide in order to support very short, between-centres work), the tailstock had a 3/4-inch (19 mm) diameter spindle with a travel of 2.6 inches (66 mm). A single locking bolt on its underside passed through a slot (allowing the operator some latitude in lining up with the headstock) and engaged with a tapered nut that was drawn into a slot beneath the centrally located, Whitworth-form leadscrew.
