Below left: Looking down on the cast iron tray of an early B2, it shows it was provided with sockets for a countershaft or overhead drive. The large square hole is for the belt from the treadle mechanism but what was the small rectangular hole used for ?
Below right, the tailstock support on the end of this lathe is cast brass rather than cast steel
Pittler B2 Brass tailstock support
Above and far right are shown both tailstock and headstock of Pittler B2 serial number 1253. The indexing equipment on the tailstock end was not provided as standard on the B2, this had to be driven by an overhead countershaft for some operations although it could also be operated manually.
Lever for engaging reduction gear, below is the feed lever
Headstock end showing the mandrel with worm, also the end of the collet drawbar, below can be seen the reverse gearbox mechanism
This B2 also has back gear, or as Pittler call it "reduction gear" but unlike other lathes it is not actually visible and is another of Pittlers patented inventions! The secret lies with the fact that it's internal and operates with a sun & planet system. A lever visible below the drive pulley pushes in a locking pin to connect the internal 4 to 1 reduction gears.
