NeoTech If you have a dial indicator, you will have the info you need to determine metric or inch. Set the DI and turn the crank one turn ( mark spindle and turn one rev ).

Uhm oki, if i did this right im guessing its a metric screw in this machine. So i guess i should be able to use the chase dial when cutting threads.. But not really sure how. (god i hate this machine manual). |

This video might help? Basically, the thread dial rotates at a certain ratio to the leadscrew; threfeore, so long as you always engage the drive at the same point (when one of the numbers passes the marker), the tool will follow the same path as on previous goes, so you cut one deep thread instead of lots of shallow ones. Exactly how your thread dial works will depend on your lathe. I'm lucky - mine works on both metric and imperial as I can cut both threads straight from the gearbox, but TBH my experience of single-point threading is similar to yours (broken tips), so I'm lazy and tend to use taps & dies these days. |

Since I made a swing tool I've not looked back, small threads, large ones, it does them all with ease |

Ah ok, yeah my lathe can turn both metric and imperial according to the gearbox. (have been pondering about that). And the chase dial can be attached with different "teeth" speeds i guess it is. I have just set it at 36 and havent bother anymore after that.. I thread with engage and backing off with it engaged atm. but it would be faster when doing large/long pieces (which i will be needing to in the future) to be able to run it with the dial.. But its a learning process.. i just need to figure it out. =) A swing tool you say.. i saw something about that on hemingway... wondered what it was for actually. =) |
