In the present study, three dimensional model of the spindle is prepared. Lathe tool spindle leads to unbalanced vibration and uneven tension in pulleys and belts. The stiffness of spindle has an important role on productivity and surface finish of the work piece. I straightened a 5 foot long lathe leadscrew on a commission job with two vee blocks and a bent steel yoke bolted to the workshop floor as the fulcrum point for a long bar I could lean on.Lathe spindle is considered as an essential component that makes material removal possible during the machining operation. Two examplesĪ bent track rod on our old Landrover after some idiot put a tow rope on it yielded to nothing more than a hole in a fence post and putting weight on the component in strategic positions. I have found such methods very successful in the past and only simple tools were needed. It certainly would give me the opportunity to forgive my press seeing it was that which was at fault.ahem. If you have a 12 ton press then I would have a go at straightening the spindle, of course it may not be practical to bring it back to a working condition but nothing to be lost by trying.Ĭertainly an interesting option, Brian. Gives fairly good instructions of how to do it. He has straightened shafts on different videos. You could look up ‘Keith Fenner’ on youtube. If you PM me a phone number or email address, perhaps we can sort something out. I'm just south of Cambridge so not too far away. PS You have a press I now recall, you could use that with care with the spindle supported on wooden Vee blocks The job took most of the afternoon and I sweated off several pounds! I made two softwood Vee blocks and belted the thing with a lump hammer via a length of 3 x 2 inch hardwood to the point where it ran true within a couple of thou over the length when held in my good lathe chuck. Is it badly bent? I ask because I have straightened a 3/4 inch diameter shaft from a screwcutting gearbox that had been abused by rough handling Hello John, I went to Machine Mart, I believe they sent me on to Clarke. I'm sure "Machine Mart" would happily supply a new spindle ! I make spindles and chuck adapters for many ww lathes I am in Canada so I can't help you with the shaft, but I am sure someone near you will respond.Ĭan you post a photo of what you have and some rough dimensions or what model lathe it is. Sorry Rob, I didn't see this post until I replied on your other one. What country and city are you in Rob? Would be good to know for those local to you to help. Would appreciate the help because I really like the style of lathe and would rather fix than dump. Would anyone know where I might get a new one made as a one off for reasonable price, or of course, would anyone here be able/willing to help? I cannot find a replacement anywhere, it's an old lathe. I decided to use my 12 ton press to remove the bearings, unfortunately I didn't realise there was a 'shoulder' (for want of a better word) on the spindle at one end and the bearing would only come off one way, I was trying to go the other way, after a few tons of 'she'll move soon you know'.I realised my mistake. I wanted to change the bearings on my woodworking lathe. I joined because I was hoping someone might be able to help me.won't say more here, will post in appropriate forum. Hello everyone, name's Rob, old timer from Newmarket, UK.
