I need to ask some dumb questions as it has been a long time since I was last on a lathe, which was Hercus and Myford stuff at school about 4
decades ago!
A) Because this lathe does not have a "tumbler gear" handle like the lathes I learnt on, the direction change lever is the on/off lever on the far right of the carriage?
B) In the various manuals I have found online for very similar (but not the same) lathes the following seems to be the case:
1) Fitted with a control rod (3rd rod) as above description and thus direction and on/off control.
2) Only 2 rods and with tumbler gear handle for direction control.
The closest manual I have found is a Chizhou PL300-1 CZ 1234 & CZ 1237 which has a confusing set of photos which depicts a 3 rod lathe with a tumbler gear setup and the stepped Norton gearbox.........
C) Does this type of lathe mean that to change between metric and imperial thread cutting requires cog swapping ie. take a cog off and install a different cog or is it a case of reversing the orientation of the cogs?
If cog swapping is the case, then there are no loose cogs with the lathe.......
The chuck and face plate are screw on style. Is it normal to have a reverse direction facility with a screw on chuck - isn't it going to come off?
