This is a very original BTM lathe that was made by British Tabulating Machines for the Royal Ordinance Factory Bradford during the war, being an almost exact copy of a Boley lathes (parts will interchange with no loss of accuracy, the only difference that the Germans used a metric thread on their clamping nuts and the English used imperial threads), but the collet threads matched. The lathe has never been rusty, but kept with a wipe of clean oil , it? S had very little use , but enough that the lead screws and slide ways just glide being nicely run in , smooth , silky nip kissing tight , and travel in the conventional manner , (unlike Lorch lathes of this era where you need to turn the handles anti-clockwise to go forward and always causes mistakes and confusion). The lead screws pitch are metric one full turn being 0.6mm , and can be trusted for accuracy with each having only 0.05mm backlash like new! , having a HSS tool bit and an unused spare with it. The drill chuck on the runner is a 0.3 – 4mm Chinese made one, but it works smoothly but more important drills accurately when used with a fine centre drill and gives that sensitivity touch when using small drills or taps by gripping the chuck body between finger and thumb having lightly oiled the runner sleeve. These lathes were also supplied with two tailstocks so that they could be used for dead centre turning with a runner that had a running tapered collar that either a large or small dog drive pulley slipped onto, and then different small dead centres in the two small glass tubes and an extractor drift see photo 4. The collets run true , the head nose taper is spotless and the drawbar threads not worn. It is heavy to post and I will post in two packages so the motor and baseboard go as one and all the lathe as the other , for the U. This lathe belonged to a deceased friend of mine who was a brilliant (hobby) horologist , but was a toolmaker with the royal ordinance factory and before that at the atomic researchers facility, having originally been a full certificated merchant / Royal Navy first engineer and knew how to look after his tools. This was original from the unused stock of the royal ordinance from where he acquired it but it had lost its 3 jaw chuck whilst in storage. S costly to post one box being the lathe 8.5kg 36 x 25 x 14 cm. And motor 7kg 55 x 20 x 15. M happy to post overseas if done with full insurarce.
