Need Myford change gear
I need a 40 tooth Myford change gear.
I bought a Myford Metric attachement for my Super 7, but it is missing the 40 tooth gear which is needed for numerous metric threads. Anyone got one setting around?? (I didn't see one on ebay) I got a few oddball Myford gears laying around I could trade if that is an incentive. BTW, this attachment comes with 12 gears, but I don't understand why. For example it comes with two 60s and two 55s but I don't see any setups where you ever use more than one of each to cut a metric thread. chuck |

Hmm, sounds like an excuse to learn how to make your own gears. I wish
I could make an excuse like that, but my lathe has a quick-change gearbox. |

I could make an excuse like that, but my lathe has a quick-change gearbox. My lathe has a QC gearbox too. But I cannot cut metric threads without using some change gears ahead of the QC gearbox. chuck |

About the multiple gears, do many setups use the 60's and the 55's? If
they were used in almost every common setup, it would make sense that Myford might anticipate unusual wear and include a spare of those gears likely to wear down fastest. Besides, those gears sound like some of the largest in the set. Large gears have more teeth, so the probability that a tooth will become broken or damaged is higher than on a small gear. |
