basic dividing on a Chester Comet lathe

(1/1)

wheeltapper:
Hi
I thought I'd show you how I do this.
this is my lathe, it's a Chester clone of the sieg c4.

CAUTION turn the power OFF before you start anything like this!!



here is the inside of the drive housing

to start off I made this fitting, it's a flat bar with a square piece with a cross hole and a clamp screw bolted on.

remove the two bolts shown with allen keys


and, using longer bolts, fix the fitting




I then made an expanding sleeve to fit the lathe mandrel



fit this in the mandrel


and then fix a change wheel to the end and insert the detent pin so it engages with the teeth

the expanding sleeve can also be used with a handle

a close up of the drive pin on the handle


very useful for screwcutting short threads, the lathes lowest speed is 100 rpm, a wee bit too fast for my liking.

and thats it, I hope I haven'd bored you too much :big:

cheers
