Thread: Metric Bantam lathe and 19tpi threads
04/05/2016 23:55:20

Evenin' all

Just had a very similar problem on my own Bantam-cutting a 26tpi Cycle thread. Worked it all out with the aid(?)of the formula in the book. According to my sums (Quiet at the back, there!) you need a 28 t driver and a 57t driven (leadscrew) gear compounded with 120/127t idlers as 28/120 x 57/127. The gearbox levers are pos B and pos 1. These gears are standard Bantam for the English and non-gearbox models. The 57t is non-standard for the metric box unfortunately. Incidentally, for the 26tpi the settings are 28t and 39t, compounded as above, levers at C1. Couldn't get hold of a 39t so made my own. Unfortunately some of these gears are a bit scarce, but occasionally turn up. There's a 39t on fleabay at the moment. There was a query somewhere else about tooth sizes. They are 16DP on the 800/1600-otherwise known as the Hawk/Eagle/Condor. Hope this helps.

Thread: Colchester Bantam Lathe
28/05/2014 21:37:11

Hi, everybody. New kid on the block. Talking of saddle stops-I am looking to make one for my Bantam mk 1 as they seem to be about as common as hen's teeth but could do with the internal profile. Dimensions I can work out from that. Would anybody who has one be so kind as to park it on a sheet of paper and draw round it? It would be greatly appreciated. Thanks in advance. Sandy
