[attachment=15884][attachment=15885]Ok, please bear with me.
Bought a Chinese lathe from the bay!
It's not too bad me thinks, and after some messing about by me I can get it to turn steel 350mm long down to less than 1/2 a thou...…….. over said length, to say I'm pleased is the understatement of the year! (think canine with two willies!!!)
My problem is I never got a manual with feed rates etc from the company I bought it from!
So if I can supply the gears, can anyone supply the feed rate gear settings?
I emailed the company I purchased the lathe from about feed rates, and got told "bigger gears mean smaller feeds"...…..Yeah, right f-in really helpful!!!
It's a lot to ask, but, if you don't ask, you don't get!
So.…..Headstock gear is fixed 56T, then looking at pic, A/B C/D (E/F leadscrew)
I have 84T, 80T(x3), 72T, 60T, 52T, 50T, 40T, 33T, 20T gears.
Leadscrew is 16mm x 2mm pitch.
Seriously, any help will be mega helpful!
Pic included if that helps any?
(1st pic needs rotating right by 90 deg.)
In the first picture gears are...…………56T headstock, (A)80/(B)33T, (C.)20/(D)80T, 84T leadscrew....feedrate is not known to me!
Cheers in advance peeps!
Roy.
