TDS 1 GB imperial

Post by Richard Lynch-Blosse » Thu 23 Aug , 2007 15:23 pm

some years ago I purchased from Denford what I thought were the parts to enable conversion from imperial to metric (including an unmachined banjo). having only just got around to trying to assemble the parts I realise that the compound gear is for the metric to imperial although the bango appears to be correct. does anyone know which parts I would need, where I might find them and where on the geartrain they fit?. I have a diagram of the layout but this also seems to be for the metric version. I also wish to cut a thread of 9.45 TPI. any suggestions as to how to achieve this and if I have to cut a new gear what is the diametral pitch and angle (different info suggests 14,16 and 18 as possibles) :?:

Richard,

Welcome to the forum!
I recently got copies from Denford of most of the part drawings needed for metric:imperial and imperial:metric conversions.

I will pm you to discuss further.

Hi

I looked at doing an imperial to metric conversion with back gears. A back gear solution with an imperial gearbox offers a limited set of metric thread pitches. The cost of buying and making parts drove me to look at a CNC conversion. I plan on using the Linux based EMC program. I am accumulating the parts but I haven't had time to make any tangible progress.

Good luck with your project. Post lots of photos so we can all ogle.
Regards

Dazz
