Thread: Hercus lettering system

Not sure ,does it represent a long bed model.

The "N" stands for instrument version according to one of their old brochures.I would presume this to be a lathe that had very tight tolerances.

Thanks Localele
I will appreciate it so much more, now that I know that such extra care went into its manufacture.
I so much love the older equipment and if deserved will go to great efforts to offer it a new lease on life
Cheers Tom.

Even without the "N" they are great little lathes and I have certainly learnt a lot from both the lathe and this Forum.
Post a few photos if you can Tom and a serial number so we can find out its vintage.

A few pictures of the 260
The higher speed seems to have been achieved by a reduction in the size of the pulley.

The serial number 16490 would suggest that manufacture occured about 1978 (the year I started my fitting apprenticeship) where I trained on a Colchester Triumph 2000 but the Hercus takes pride of place now. Tom

It is quite a change to the speed ranges as well.Going up by 30% and 57% roughly ,What speed is the motor?
I imagine it would have different bearings in the headstock for those ratings. A call to Hercus might get you some general info about the Instrument Version which you could share with us.
