Thread: Simple Gearing for Metric Threads on Myford ML7 lathes with gearboxes |

Thanks for all the input guys, i take it that you only change the one gear either 33 or 34 depending on the thread pitch & size. As in the picture you have put. Then adjust the gear train up to mesh correctly. |

Yes I see your point. I was thinking of the looks rather than the safety aspect. The lathe is going into a left hand corner, with enough room to open the doors for gear access. I could actually mount the control panel on the left wall which would in effect be in front of the machine. Thanks. The lathe is going on the left of that bench. Which I have beefed up to 54mm of hardwood ply bonded & screwed together, did not want any vibration. |

Hi. My sixpeneth. I spent the last 25 years of my career designing ,building & installing control panels to the food industry. Most of the inverters we fitted were Jaguar & some were Seimens. Some had very elaborate control connections to control rooms etc. Now well retired & the fresh owner of a very nice Myford super 7B. today I have stripped of the motor & pulleys ready for the 2nd hand inverter I just purchased. It is an Omron, which are quite expensive new. I am currently building a control box for it & your topic came to mind. I don't know if the cheaper Chinese inverters have the function but in the configuration you can set a ramp up time, & a ramp down time with the start stop buttons. There are other connections for various other options. One option is that I can configure an E-stop which will stop the inverter instantly if you set it so. Not braking so would not have thought a chuck spin off would occur. I plan to mount the control panel on the wall behind & above the lathe on a arm. The 2nd e-stop I think would be better at the front for obvious reasons. |

Thanks guys. Quick response. Just need to work out where the tumbler gear is within the set. Looking at the myford pictures I have it refers to the tumbler gear which is a pair side by side just below the main transfer gear from the headstock. Made of tufnol. Surely not them as they are a pair for forward or reverse & both the same teeth. The gear below them is a pair of gears. Any help or a diagram would be great. I know it's new years eve & all. Happy new year to all. Regards Steve. |

Is this thread still active as it looks quite old. Reason is I have just purchased a Super 7B with qc gearbox on imperial. I would like to screw cut metric,just the basic sizes say 5mm to 8mm. I have downloaded the pdf sheets. But I am new to lathe type work so not sure which gears to look for & where they are on the machine. I know where all the gears are but just not knowing which ones it is that are changed. |
