I shall find myself a copy. This is a great hobby, but I think it will take me my lifetime to get any good at it. There is so much to learn. I do have a copy of the Super 7 Manual, but it helps beyond measure having a couple guys on the interwebs to help me understand it. I am just getting the terminology down. I chalk this weekend up as a win because I did just run a perfect 18 TPI. ITs a good thing no one is timing me, this is the culmination of about two months of learning. Maybe I will be able to finish the Stuart engine some day |

FIXED ! I love you guys I wish you were my neighbors! I changed out a 20T with a 24T and BOOM! My chart is now consistent with what the lathe is cutting! Now to order that oil gun off the internet.... |

Well, I think you have figured out the problem. I will take off all gears, count all teeth...again, and set back to the original. I dont know why my dad had a metric configuration setup. He was building a sterling steam engine before he passed. Let me get my shop clothes on and I will start at this. And maybe go to the store to get an oiler. Thanks to everyone, I thought only the little oil cylinders needed oil. So, I'll be off to the store to get an oil tube. Oh, and then I get to loo forward to cleaning out everywhere I greased. That should be fun. I think the big gear is a 72, not 70, but I will count again. I love the sharpie idea, I will waste less. |

It looks like I have a 21 in place of the 24. I'll be dipped. Thank you guys for the help. This place is great! I've spent two months learning how to cut threads. This has been quite the boggle. Simon, Chris, Pete, Brian, Ady1, you guys are the Best! |

I am a novice. I inherited my Dad's Myford Super 7. I used this as a youth with my dad, but now I'm really getting into it. I know how to read my gearbox. I am trying to get 18 TPI. When I try using 2B, I get 21TPI. 1B gives me 19.3 TPI. 8A gives me 17 TPI. I measured both with a thread gauge, and manual calculations from 3" test runs. What am I doing wrong? No setting equates to what it should. Oh, and how in the dickens do you grease the fitting that is too small to accommodate a grease gun? I ended up pulling the spindle out and packing it by hand. Is there such thing as a british grease gun that has a smaller head? |
