DIDN'T HAVE THIS PROBLEM IN PREVIOUS VERSION (18 SPEEDS) AS THERE WERE 60 TEETH AND 64 TEETH GEARS IN THE SAME LINE
AND WITH COPY / PASTE USED IN DRAWINGS, WELL S...T HAPPENS.

Thank You LMMasterMariner for sharing all of this with the community and throughout your journey. Most Impressive!! Quite the Amazing build and design journey you took to the finish line. Loved the video compilation and the music was perfect imho! Was that gear setting accordion, paper or metal...looked like metal reduced and formed??

Thank You again for sharing a masterful design and build!!

gear setting accordion as you call it is just printout of the drawing in actual size 1:1 ratio and I actually used original gears to check if everything is fine. Gears were created by program GearDXF. Then opened by LibreCAD and rotated if required. (both freeware programs) Then copied to and completed in Paint and saved as 16 colour Bitmap image.

In the video between :55 and 1:00 is that a piece of paper to set the gear engagement or metal. Didn't use the right words sorry...maybe setting the lash?? I use paper on my Mini Lathe when changing gears or move the banjo.

Yes. That's piece of paper. The same thickness which I use when changing gears at banjo.

Hello all, new forum member here. I'm repowering my Logan lathe at the moment and was searching for a solution to having more than 3 speeds 😀.
Thank you so much for contributing to thw machiing community with your many published designs LMMasterMariner, however I seem to be unable to find a link for the attached files!
I have a paid membership, and I see the sentence "🖇 attached files" but no files, or hyperlink.

Are these plans still available?

Cheers! 🍺
