I really hate to complain about freebies but........
I was trying to read the change gear chart on my Logan 200, I really need to get some better lights in the shop! So I headed off to the Logan site, sure enough, there was the chart in large print. Great. Only trouble was, the gear diagrams that went with it had broken links. :( Any chance they could be updated?
That better now? Be sure to refresh your cache.

Now that I have THAT figured out, are there any charts for the 127 tooth metric change gear? I'm too cheap to buy one but I might have a cheap way to make one. (Have my vertical CNC mill guys make a blank with 127 index holes, use that in a simple fixture to index with a pin and cut the teeth. )
I presume that you use the 127 tooth on the carraige shaft, use a 50 tooth to drive it. The various combos of 16, 24, 32, and 64 will get you
1mm, 2mm, 1.5 mm etcScott S. Logan wrote:

Be reminded that while you can cut exact metric threads with a
127 tooth gear, the thread dial will no longer work (it will still rotate OK, but you can't pick up the thread), and you will have to leave the half-nut engaged. To return to the start, you must retract the tool smartly while stopping the lathe, and reverse the motor rotation to run the carriage back to the start point, and reset the tool. Be sure to have enough space between the tool and the start of the thread so all the backlash will be out before the tool engages.I have seen mach>Now that I have THAT figured out, are there any charts for the 127 tooth

Actually, the original set up required a 127T and 100T.
It is also possible (and easier and less expensive) to use a 47T and
37T pair. With these, you do not need to replace the Change Gear Bracket (which is not long enough to hold the larger gears).See:
Enjoy!
Thanks again! .pdf is filed away in my 'Machine tools' folder. From the looks of things, I probably won't be going that route.
I used an Enterprise lathe for my last round of metric threads. It has built > >
