Boxford lathe Tumble Reverse Gear Early Models
This gear is for all Models prior to Serial Serial No. 11-13513 - the introduction of the Mk.2 Models that have a single lever on top of the headstock to engage the backgears. 32 teeth and a 14.5-degree pressure angle. Made in the correct grade of cast iron - we have sold these gears for over 30 years.
For later models (the Mk. 2 AUD, BUD and CUD) with a 20-degree pressure angle see here.

38-tooth gear to fit on the headstock spindle and engage with the headstock pulley as part of the backgear system.
The gear was made with two pressure angles:
1) 14.5-degrees for older lathes with a swing-type quadrant lever on the front face of the headstock, like this http://www.lathes.co.uk/boxford/img10.jpg

RING GEAR to repair the main spindle Bull Wheel (the larger of the two gears on the main spindle). Machine off the damaged teeth and shrink or Loctite the new gear in place. Can be used on all belt-drive models the A, B, C, AUD, BUD, CUD, ME10, CSB and those T and TUD non-screwcutting lathes fitted with backgear - but not the VSL which had hardened backgears. PLEASE NOTE: this is a 14.5-degree gear, not the later 20-degree.

Boxford & South Bend Backgear 24-tooth Shaft. We can supply - on a service-exchange basis - a backgear shaft fitted with a new steel gear. The large gear can be knocked off to save postage (though some early shafts were one piece). Early gears have a 14.5-degree pressure angle and have no markings to show this. Later gears are 21 degrees and in this case the shaft is stamped "21" - though it's sometimes hard to see. We can supply both types.
Pack your broken gear carefully and we can send you a service-exchange item of the type that matches yours. Send to:
