Based on G H Thomas' design, this driving handle can be engaged then disengaged in seconds. If you rely on pulling the chuck key or drive belt when cutting short or blind threads, removing chucks and collets or running small taps, you'll know how slow and frustrating this can be.
Keep this tool handy and you'll be amazed how much use it gets. Along with all necessary materials, the kit includes drawings for both the standard and long handled version with off-set to clear the Norton gearbox (pictured). There is a single silver-soldered joint for which you'll need solder, flux and a propane torch.
Please note that this attachment is NOT suitable for Myford's more recent Big Bore lathes.
