That scary lathe gear chart... And some lathe tips...

- A short video describing how to interpret a lathe gear change chart, and practical examples of how to correctly set the gears. Also includes a nice way to sort and safely store lathe gears, as well as other handy tips.
No lathe was harmed during this video...

Just found your channel and Subscribed. Very interesting. Nice lathe
Thanks! Its done well over the years, finished some lovely projects. Thanks for watching my videos! There's more training material in the pipeline for Adendorff machines...
Hi. Picked up on this feed. Great to see SA guys doing vids. Have the same lathe as you. Added a clutch, which makes life a lot better and no sudden knock on start up. I felt sorry for those gears.
Some good mods you done there ++
Very good thanks
Subscribed, very similar to my lathe
well explained video, thank you! subscribed
Awesome video... Got same lathe....more videos on the lathe pls... 👌🏻👌🏻
Check out czcams.com/video/IPmPqJ1BMkg/video.htmlsi=YMQ96-XNw3m329hD nice lathes!
Thanks for the video!
Really good movie
Brilliant video. Still getting to grips with this machine and I did not understand how to engage longitudinal and cross cutting power feeds. I mistakenly used the halfnut lever 🙃🙃... believing the actual power feed lever is just a select lever. (The way it is setup on my Colchester Student)
The result of this was that I believed the cross cutting feed wasn't working and on top of that, while I have installed the slowest gearset, the feed rate was still incredibly fast.
Not to worry, many have done the same thing! The machines are pretty robust so you probably didn't damage anything... Thanks for watching!
@@Lukers_tinkering in fact I went and check with my new found info and the facing/cross feed is not working!
But I do understand the operation better.
The main difference between the Colchester and the Adendorff as far as the feeds is concerned is that the Colchester uses an additional shaft for power feeding so the leadscrew is only used when threading. The arrangement on the Mac Afric machine caught me a bit of guard.
The 9A South Bend lathe I have has the same type of setup as the Mac Afric lath although the controls operate more intuitively but this is likely due to the fact that the 9A comes with a quick change gearbox.
I guess I will need to contact Adendorff to check on possible repair options.
Hello,
I just got one of these lathes, But no change gears, I can't find them anywhere. Do you have a list of the gears that came with this and what pitch they are as in 1.25 etc. And also the shaft size for the hole in the center?
Thank you for whatever information you can give me. Mark
Hi Mark, the gears needed are on the gear change chart on the side of the lathe or you can do a screen grab from the video. The shaft size should be measured from your lathe. I'm not sure of the modulus, and unfortunately I don't have a gauge.
@@Lukers_tinkering Thank you!
Read the instructions that comes with your specific machine.
Reviewed a few lathes, and the instructions have never explained how to correctly set the gears. In fact, most instructions aren't very good nowadays 😕
