One day while using the lathe I had the not very original thought that if I could turn two handles at the correct rate then I wouldn't need the taper turning attachment that I can't afford anyway. Some time has passed and I have finally developed the idea to a stage where I have something to show. Here's the lathe with a gear tooth position sensor counting the revolutions of the spindle. This is the cheap ebay topslide with a worm drive and stepper motor added. This shows the general arrangement with an old laptop, an old computer power supply and a box with some home made stepper motor drivers. I wrote a program for the computer to control the topslide based on the number of revolutions of the work. It works with the lathe on its finest feed. The fourth shows the results of a test with a MT2 socket on the taper - I was delighted with this as the fit is excellent although the surface finish could do with improvement. The last picture shows the result. Russell |

Oh I doooo love innovation, especial when using old bits, as in recycling. :D :D Brilliant ! I award you Madmodder, Star off excellence. :clap: :clap: :clap: :clap: :clap: :clap: :clap: :clap: :clap: :clap: :clap: :clap: :clap: Well I would if I had one, it is time some recognition system was set up to recognise great ideas perhaps with a button for "I love this", get so many and get a star. :lol: I know all members are stars, I mean one like we got on our books at school if we were really good. :nrocks: Many thanks for a great article Russell :beer: Trev |
