WM 250/280 lathe change gears calculator
« on: February 25, 2020, 09:40:01 AM »
Impossible to find the change gears for some threads on my WM250 Lathe. Good lathe but poor threading info.
So I wrote a change gear calculator. Probably buggy, but seems to work OK for me. Windows 10 64bit, or Windows 32bit compatible with Windows 7/XP . No installation, just create a directory and extract the exe file into it. It does write a gears text file which can be updated in the program or via Notepad etc.

Hope someone finds it useful.

Best Regards

The WM250/280 is a 7x mini lathe, right?
LMS has a change gear calculator online:

@Chuck
WM250/280 is a different beast to the mini lathe, closest I can find is a grizzly 9x22. Although I found a calculator for the grizzly it did not work on my WM250.
See : https://www.warco.co.uk/metal-lathes/303007-wm-250v-lathe.html

@kayzed1
Dowloaded and unzipped OK to a win 7 computer, using 7zip, but it is a 64 bit program so its only good for Win 10 64 bit.

I've now added a Windows 32bit version which should be Ok with Windows 7 (tested) and 10 (untested - dont have 32bit windows 10).

Best Regards
