As a logical downward extension of the existing speed ranges, it would be good to have the lowest speed around 30 rpm. Since you've already got the first reduction gear as large as will fit, that means reducing the drive pulley to a little less than half it's existing size. That might exceed the minimum diameter that the belt could handle without slipping or breaking though.
Hi, I'm already at the maximum minimum diameter with the new drive pulley extension. I've already done some machine tapping and 68rpm is working out really nice :)
Nice work, I have the same lathe and wondering if I could get a lower feed rate, I guess this also gives a lower feed rate but at the cost of too slow for cutting. Have you tried gettting feed rates lower without loss of speed? I know other lathes have separate drive systems for feed, sadly not our lathe!
Hi mate, to get a slower speed rate, you’ll need to alter the change gears that came with the machine. Do you have the set of change gears that came with the machine?
Yes, I have them, is it just a matter of using a different combination? Also, would like to PM you if possible since we have the same lathe we may be able to share experiences over time
Hi, from memory it’s about 1000 rpm, which is fine for my finishing cuts. I mostly use mild steel for my projects. Since the mod. I haven’t needed to change the setting on the pulleys so I’m extremely happy with the result, making it worth doing. Wish you the best with your lathe, I’ve had mine for 6 years now and I love it 😎
Great little project. Well thought out and executed.
Thanks for your positive feedback!
Impressive
Excellent video mate. Well done on the mods.

Think this will be the 1st Mod I do to my new 3008G. Have you measured the RPM with the spindle gearbox set to the higher speeds ?
