Not mine unfortunatelyThats an unusually clean lathewhat is it?
One of the new Colchester students , don't make em like they used to but still alot better than messing about with my Chinese mini lathe at home.
Even more tempting to try and cram a big lathe into my garage after getting to use this for a while , carbide quick change tooling is also a difference and nice to use
Very nice. What rpm and can you take a close up of the tool tip please?

Thanks
1700rpm and what I would to refer to as a finishing tip I'll get a pic of the box next time for the exact number , very nice to use and easy to get a good finish in my experience if I'm at a higher rpm and decent feed rate.
This is the tool here as I said not certain on exact tip but will find out
No that's great thanks.
I also use these pointy tools for light cuts and finishing. They give a much better finish especially on my old Triumph lathe which only goes to 1000rpm.

Agreed far nicer finish every time changing rpm depth of cut etc can change it so just about playing about with feeds and speeds etc and when I get a good finish then taking a note so you don't have to repeat that process again and can go straight to the best finish parameters.
Indeed so. Can I have one pleaseThat's just a big Chinese mini lathe

That looks remarkably like a Harrison M300

It is. Colchester bought harrison. 600 group then moved production to Taiwan. Hence why XYZ lathes look practically Identical too.

They probably work just as good. The Taiwanese got pretty good at making lathes.Never turned on anything else so nothing to compare to , yet
Taiwan have been making good lathes for many years. They would NOT be amused to be called Chinese!
I have a Feeler lathe which they say is just as good - if not better - than the Hardinge it was copied from.

Well I don't think they would mind since their official name is Republic Of China.
Lol it gets very messy!
They are the true Chinese - or Free Chinese as they like to be called

Did you single point the male thread or use a die?

I didn't have a die that size but the guy did so I single pointed it to about 90% depth and finished it with his die.

Yep, sad really. The lifetime cost and carbon footprint of a 70s/80s colchester that has had a rebuild after 30 years is so low. Compare it to polluting chinese industry, an old lathe rebuilt is practically a environmental success story.
Look at that cutting edge engineering on youtube, ever machine in his shop is chinese. I guess he isn't a precision machinist he is just using his machines to repair plant, but still, Sad.
