Tutorial for RideTheGearTrain - Part 2

RideTheGearTrain Tutorial Part 2

The final part of a series of tutorials about how to use the free online software - RideTheGearTrain. If you haven't watched Part 1 you need to choose either Part 1A for Chinese Mini-Lathes or Part 1B for all other lathes including South Bend Clones. Then you can move on to this video for Part 2.

RideTheGearTrain Tutorial Part 1A for Mini-Lathes

RideTheGearTrain Tutorial Part 1B for all other lathes including South Bend Clones

It takes the user through the process of choosing the lathe and its gears and other specifications required for these lathes. There is another video, Part 1A for the Chinese mini-lathes. Part 2 will show the entry of the thread pitch (or TPI ) and explains how to use the results. Users should choose either 1A or 1B before proceeding to Part 2.

The software calculates the gears required to cut a particular thread using a lathe. The gears in the gear train control how fast the lead-screw turns to make a thread. The user enters all the gears they own, and chooses a gearbox if their lathe has one. Then the program systematically tries every possible combination of gears and gearbox settings. It calculates the thread produced by every possible combination, and compares it with the required thread pitch. If it matches within the required error limits, it displays the set of gears in a table.

Each solution in the table is displayed with a button labelled DRAW. Clicking that produces a scale drawing of the gear train, so the user can visualize whether there are likely to be any problems fitting the gears together. The program also analyzes the fit to detect any problems and shows the user where idler wheels can be inserted into the chain to overcome any problems.

Got this app 2 years ago. Have a 60yo lathe needing 'love'. Now, using the app, ready to cut a crossfeed LH thread nut. Found few gears to suit, but checked up alternatives. Found it very helpful. Thanks for this.

I have the same lathe and would like you to give me the panel in mm and the gears needed
