So, I was given a lathe that had electrical problems.
I sorted those problems, and I am now looking for some simple projects so I can learn the machine. My first thought is to turn some clutch pulleys out of brass. Do you have other suggestions? Attached thumbnail(s) ![]() |

Find an old retired machinist to teach you how to first- 1. grind cutter edges 2. set up a cutter in the toolpost at correct height and angles. . that's a 4 way toolpost and requires shimming cutters to correct height 3. show you the correct chuck rpm speed and correct cutter feed speed. The tendency is to turn too fast. 4. after all those, start on PVC or wood. . . 5 remember no matter how fast you think your reactions, hands and fingers are, the chuck is always faster and a lot stronger. It's not rocket science but it's easy to hurt yourself badly. . You might want to start by positioning the machine and leveling the bed. Then make sure the headstock is parallel and perpendicular to the bed and center of tailstock. Determine the off center runout of the chuck. .Those Chinese chucks are usually spec'ed at .003 off center as the normal limit when new . If not set up properly, no matter what you do, your finished project will have taper and be out of square and off center. 2nd that,safety 1st. An intro course at a local school will get you up to speed on the operation of lathes,the inet is a fount of info. Loss of body appendages is a distinct possibility if not properly trained. Due diligence is the primary impetus and fear of agony the second. It's a machine,and will not ask if you are competent,just prove if you are not,instantly. https://www.youtube.com/watch?v=FfcukAV_Zhk A simple op,one that requires practice to perform correctly and accurately to a honing tolerance. The Wright brothers machined their engines on a lathe far cruder than the one you have there. An expert tuneup of the hard parts is likely in order if the hours are beyond 20K. https://en.wikipedia.org/wiki/Charlie_Taylor_(mechanic) (edit)oh yeah,keep it spotless clean,do not spit in the sump. / |
