MILLING /DRILLING SPINDLES
Below right: is another accessory, almost certainly not made by Pittler but possibly supplied by the George Adams Pittler company. A heavy duty milling/drilling spindle, this is fitted for Morse 1 arbors and mandrels together with a drawbar, Dating it is rather difficult although Morse tapers were invented as far back as 1863, 26 years before Pittler began production.
The swivelling pulley wheels when connected to the overhead drive permit the device to operate in various directions and angles including both horizontally or vertically for milling and drilling.
A nice little drilling/milling head, MT1 made by Potts in the early 20th century, it fits on the Pittler tool block exactly!

This accessory bolts onto either the standard Pittler cross-slide or the compound one
Left: is another small milling/drilling spindle, Made by Potts in the 19 30/40's it fits the Pittler B2 exactly on the square cross-slide together with it's threaded bolt. It also has two small pulley wheels which can be set to accept the drive belt from various angles but not in use here.
It's shown here milling a spiral with a 1/4" end mill fitted in a MT1 collet. The overhead drive powers it via the mechanism at the tailstock end so the lathe is being run via the leadscrew itself. The chuck turns very slowly as the carriage moves slowly across.
