What DP are the Granville gears? You might be able to use gears off a more common lathe that used the same DP. Eg Myford 20 DP. Drummond 14 DP.  And I forget Boxford’s.

Bazyle beat me to it!  If you get completely stuck, pm me the details and I can print out a couple in either PLA – carbon fibre or glass fibre reinforced filament, with your choice of pressure angle, or both.

The Myford gears have a 5/8″ bore with a 1/8″ keyway. Should be adaptable. Plenty on that auction site, but they are not giving them away of course.

Yes, let us know what dimensions you have – if something common can be made to fit you never know what people might have lying round under the bench.

..plus you might well find a couple of years down the line that it becomes desirable to have other/different tooth counts..

EDIT – just noticed you have placed an ad, in that case definitely post some more details, ‘cos you’ll be more likely to a receive a better response if you can describe what you need in terms of describing the gear, rather than the (rather niche) lathe brand, maybe?
