Hello all,can anyone shed some light on what the letter H stands for on the warco WM250 lathe Thread and feed chart? I am right in thinking that the L is the lead screw? Any answers gladly recieved.
Regards Pailo

The 'H' is for the spacing collar. You should have a couple in with the change wheels. You might find one on the lathe on the end of the leadscrew. Why it is designated 'H' is beyond me. We might find someone who is fluent in chinese who could help, me, I am only fluent in b****ks, or so I have been told.

Hello Dusty.

When I read Your message I remembered that in the thread and feed chart of my Emco Compact 8 the H has also the same meaning.

In the manual page it is legended as douille (entretoise) wich translated to english using google.translate.com results in sleeve (spacer).

You can see the manual's page here:

Oh! By the way. When I bought my Emco lathe, made in Austria, all the chinese were still Maoist...

Just for fun, You can also see a true chinese poster from the seventies showing a large lathe and some chinese people admiring it.

Note: Sorry for the boxes and their shadows in the corners. I used them to prevent the poster from scrolling.


Best regards
Dias Costa

Thanks for the info chaps,have been wracking my brains as to what it stood for.I am thinking that they are the ones that have the key on them or are they plain spacers?

Very colourful poster....
 
I was in China at the end of the 1970s not long after Mao died and absolutely everyone either wore combat green or combat grey fatigues.
It was a big contrast with the west.

I think if you tried wearing anything else then you would be regarded as "decadent" and draw unwelcome attention from party reps and officials.
