Very nice indeed Stew. Are you living in that shop or what? It looks like you have got some sort of production line going, banging out bits all over the place. John |

Thanks John What I'm finding it that as I add to my tooling, bits get "easyer" and quicker to make. And I also find that I notice and learn a lot from my visits to you. :bow: Stew |

Hi Chaps Finished off the reversing frame this afternoon. It was just a matter of turning up and riveting a pin to the frame and a final bit of fitting. This is the frame with the arm to the left And to the right The toolmakers clamp is just there to give a bit of purchase to the screw. It just needs a bit of cleaning up not to much bling mind as its to be painted Blackberry Black I've got a chose with the handle buy a small casting or make from bar stock, I'm going to make from bar stock its just like making a small fly wheel and whilst I'm at it I'll make the rest of the handles needed, but before that I've got to do a bit of work on my Rotary Table. Off to a pop concert in the forest tonight Rock on Modders :headbang: :headbang: :headbang: :nrocks: :nrocks: :nrocks: :nrocks: Have fun Stew |

Now that I've got my RT sorted I'll make the winding handle for the reversing gear. First job turn up a blank 25mm dia by 5 mm thick, trapand a the front face, same as for the small handles, centre drill and drill 2.5mm Remove chuck and job off the lathe and mount on RT, centre RT an the quail axis simply by having it lose put a centre in quil wind it down onto the job and let it pull RT central tighten RT zero X and Y axis. Job Done Off set the X and Y the correct amount then nice and steady and methodicaly drill the corner holes 2mm. Then with a 1/16 burr take out the meat to form the spokes. Mount the chuck back on the lathe, give it a bit of a polish, and part it off Clean the spokes up with a file, make a handle and silver solder it to the wheel. Thats it the reversing gear completed. I'm going to start on the other end now the cross head and the slide bar and the motion frame Have fun Stew |

You're really enjoying that swapability between the lathe and RT aren't your Stew? Now you know why I had been meaning to do it for ages. Lovely bit of work there, no holding you back now. John |
