Ok well this project is being restarted following a break to build traction engines, paint my house, build my 7/8ths scale Exhill Works layout etc...
Had a massive tidy up and went through all the parts, so a bit of an update...
Having built the Virgo engine and bedded it in once id resolved an issue this is now running on air as sweet as a nut, ive been working on the gearbox / transfer box to get this running correctly (currently on version three) while i sort out bearings and work out the gear shift mech..
