Hi there NeoTech, I'm new to this forum and this is my first post. Regarding your problem with driving a rotary table from the leadscrew I think this could be quite simply achieved by using a toothed timing belt and and 2 idler pulleys to enable you to change the plane of drive from horizontal to vertical. This setup enables you to turn/twist the belts through 90degs and changes the plane of the drive. I have seen this method used to drive induction disc valves on competition 2 stroke motors where the drive is taken from the crankshaft end and changes plane to propel the disc valve which is on the intake face of the cylinder and 90 deg out of plane with the crank. Hope you can get a picture of the setup from my description, if I can find a pic anywhere I'll link it for you.....Bye for now, OZ. |

NeoTech, check out this photo of the disc valve Konig 500 GP motorcycle engine and you can see the belt path I am trying to explain in my earlier post. I have seen better examples of this type of drive on other disc valve engines,such as Helmut Fath's flat four 2 stroke,though I'm not yet seeing a decent photo of that arrangement. The flat or face spiral cutting setup you're trying to achieve would be really useful for cutting a scroll plate for a 3 jaw chuck.....OZ http://www.odd-bike.com/2013/04/konig-500-gp-outboard-powered-underdog.html |
