Hi guys, Long story short, it seems like i will be getting an old lathe within a few weeks. At my school there are two old AI DR1 Lathe's and with an upcoming new building they have to go by the end of next month and will be replaced by new ones. As a school project i completely disassembled both of them with my students just to show how to disassemble a machine properly and what it takes to rebuild it. One of those is already "restored" with some new parts but not a re-grind and is sold, the other still needs some parts to be refurbished and will be following me home. The lathe is quite similair to this one and does have a DRO: Only thing is my wife doesn't seem to agree with me so it has to be placed and brought home quite sneaky, in other words disassembled and "lightweight" as it ways in around 1200kg in total. So i'll take half of it home and make it a bench top lathe. My questions are: 1 I exchanged the motors and this one's shot to bits and needs 380V/400V which i dont have at home. It should be around 1hp and i can get it refurbished but this takes time and money. The last of which i'm not allowed to spend on something i'm not supposed to have.. :fan: Do you guys think its possible to take an old 50cc 4-stroke engine from honda wich should be sufficient in hp and hook it up? This way it is as powerfull as it should be, and i don't need to have an 380V output in the garage. 2 The triple V-belt pulley on the lathe spindle is quite shot and i'd rather not repair but replace it. If i use an 4-stroke engine i can play with the revs as i please between 3000-7000 rpm the hp doesn't change much. I can place the triple V-belt pulley of the motor to my engine outputshaft but perhaps i can replace both of them by a single pulley. (of course keeping the shot motor and pulleys in case i once refurbish the motor) What do you guys think, is it possible? p.s. i wish to use this lathe for gunsmithing (chambering of barrels) and i to build miniature engines with it. So i will restore the rest of it and make adaptations to some parts.
