Here is a solution my late father came up with to use a slotting head on the milling machine for shaping gears. He made a set of Myford change wheels on it which go up in increments of one tooth, the stack of gears is pretty impressive. Phil |

Welcome aboard Phil, that's an impressive gear making set up. Is that what preceded your Mikron Hobber, or was it replaced by it? Andrew |

Phil, More details on that set-up please! Regards, Steve |

Thats a really interesting gear setup, i cant stop wondering if that would work with my slotting head on the Aciera. =) Not to mention that slotting head tool.. Could we have a closeup on that? =) |

Andrew --- End quote --- Hi Andrew I still have both machines, the Mikron came first and then I inherited the Alexander Master Toolmaker when my dad passed away ten years ago. I remember your visit to me with a box of hobs when I lived in Harrogate. I do have a hand written sheet my dad did on how to set the machine up for different tooth counts, the cutters are genuine Sunderland ones and I have about half a dozen different sizes, the cutter is held in a home made clapper box in a similar way to a shaping machine tool. The idea is you make one pass and do a few teeth, then shift the table back and index the blank round part of a turn and make the next pass. The number of teeth per pass depends on the number of teeth on the wheel and there is a formula for working it out. My dad was a bit of a genius when it came to working out compound gear trains, I dont think your average model engineer would have come up with a set up like that. Phil Phil |
