Hi Stephen, Nick,
Gentlemen, first apologies for not responding sooner, but had to go out almost immediately after my last message yesterday, and have been out all morning today, in fact have only just switch my PC on and read your messages.
You are quite right, I did get the wrong end of the stick in thinking that the whole head stock casing may have been plastic, hence the query.
However, it’s an easy mistake, since they now make large airliners out of plastic ( the Boeing 777) I wonder if that’s made in China.
I also just managed to download Nicks link from Arc Euro Trade about the preparation of a C3 lathe, and I now see exactly what you mean, there seems to be quite a few plastic bits in those lathes.
I think it would be prudent to replace them with the metal counterparts right from the start and not wait till they break or fail.
I have also been looking at some other forums regarding the Chinese lathes, and it seems that they should be used very gently, i.e. not try to cut too much off in one go, certainly less than 0.050†as this was considered too much.
Also in some cases, there appeared to be a question of accuracy, though nothing specific was mentioned.
Still I shall have to dig a little further before I finally commit to buy.
Thank you again both for putting up with my ignorance, and helping to better understand these Chinese lathes.
All your further information is very much appreciated.
All the best,
Brian.
