Anyone know where I could get an online copy of a manual for one of these ?


I am a little short on funds to be paying 35#s for one from the above link.

Thanks !

My main question is it looks like it has 100/127 tooth gear on the rear hub to cut both types of threads.
I was not sure if I just flip flop those two gears or if there is a more eloquent way to do it.
I did not see any type of lever to switch between the two.

I would also like to know how to interpret the dual lever QC for threading.

Re 100/127, if your lathe has a metric lead screw it may be 3mm pitch whereas the same lathe with an imperial lead screw would be 8TPI. The metric lead screw is just a little finer in pitch than the imperial lead screw.

Therefore for such a metric lathe to cut imperial threads the lead screw must turn a little faster so the 100 gear is driven by the lathe spindle and the compounded 127 gear drives the quick change gear box.

On my Chinese lathe I can remove the pinion from the QC gear box and place a spacer under it so as to engage with the other gear which is not exactly elegant but neither is it unbearably onerous.

Look at the lathe importers and these guys have free manuals online. You will have to look for the model closest to yours. They all are modeled on pretty much the same designs on those little ones.

They missed the picture of the one sold by "The Great Big Electric Motor Company". I actually saw one like that
