BOMBSHELL!! …at last!

[Andre ROUSSEAUParticipant @andrerousseau66124]

Finally, one Chinese mini-lathe manufacturer has listened. Get this: a 450mm b.c. lathe with a 38mm spindle-bore and a decent 1,100W motor. Their milling machines aren't too bad either:

Your new mini-lathe…

Your link doesn't work

I had a look on ebay and they do exist

Thanks, Andre and Ady

You must feel like a proud father, Andre

I will follow the new link asap … lest it is deleted

Not quite a mini-lathe at 210mm swing but a useful size bore.

[OldironParticipant @oldiron]

Nice big spindle but 850W motor not 1100W. Maybe there is another out there some where.

This appears to be the enlightened manufacturer: **LINK**

… impressive revenue for 51-100 employees in a small factory

Interesting if you go to the manufacturers website (Dijin) the model BHC210V is listed as having an MT3 taper in the spindle, a lot smaller than the 38mm suggested! The manufacturer also quotes the power as 650w so everything is going downhill rapidly. From the manufacturers front page if you click on the model you immediately are taken to AliBaba so beware the 40 thieves.
 

The machine looks a lot like the Weiss models which Chester and Warco sell. I think the phrase "Caveat Emptor" applies to anyone thinking of getting this particular item.

Serious question, John

Do you mean ‘beware this manufacturer’ or ‘beware the metalwoman in Halifax’ ?

MichaelG.

[JourneymanParticipant @journeyman]

I was thinking more along the lines of checking the specification actually is what you are getting, which probably applies to any seller.

I did … and this is what I read:

Spindle bore	38mm
Taper of Spindle bore	MT5
Range of Spindle speeds	50-2500rpm
Taper of tailstock quill	MT2

Bore size may not be everything. When buying my mini lathe I failed to appreciate that I would be limited by the bore of the small chuck, not the headstock, meaning more overhang and wastage than I would like. All part of the learning curve for me.

[JourneymanParticipant @journeyman]

Yes I have also found that. Two different models BHC210V and BHC210VB the B presumably standing for big. I could see no mention of MT5 though on the page I found just the 38mm bore. It all depends where you land from the internet search seems to be several different interlinked sites. It all serves to confuse the unwary. I stand confused!

John

[John HaineParticipant @johnhaine32865]

On the big bore Super 7 one can get confused by the claim to have an "MT4" taper. It does, but they don't tell you it's truncated so a standard length MT4 arbor will not fit – it has to have the narrow end cut off. Maybe there's something similar going on here?

Oh well … no point posting specific links as they would probably be moderated-out.

The main point is that someone, somewhere, sometime, has actually jumped on the waggon that Andre set rolling.

[not done it yetParticipant @notdoneityet]

Weight on the net says 75kg – but 95kg on that epay item from Halifax

Possibly the input power from the mains is 850W – but what is the output power? 400W?

As usual, those that buy ‘blind’ may well be short-changed on what they expect/hope to get. So John (Journeyman) seems to have hit the nail securely on the head. “Caveat Emptor" applies with a vengeance, IMO.

Spares? Repairs? Service? Warranty? Accuracy? May be others.

Does the manufacturer have any history regards reliability and quality of product ?

Shame I can't see anyone selling just the headstock and tailstock riser. Looks like it would otherwise be possible to retrofit it onto bog standard minilathes

One more thing that I forgot to mention earlier:

I admire enormously what Niels has been doing, but I do come at this from a particular perspective … I am much more likely to be machining details on the end of a Brass or Aluminium Alloy tube than I am to be taking heavy cuts on big lumps of ferrous materials.

For me … The 38mm bore is very attractive, and 50mm would be even better !

But we must accept that these bored-out machines are still ‘lightweights’ … The prospect of taking big cuts on lumps that are more robust than the headstock assembly is quite daunting.

[BazyleParticipant @bazyle]

Hum, Does the UK market count for anything? The drive for big bores on hobby lathes is driven by the USA gun nuts – just look at the 'gunsmiths lathe' specs and that is the difference.

[JasonBModerator @jasonb]

A big bore does not have to mean you need to take big cuts but it can be handy to simply face or work on the end of a larger dia piece of stock then whip it out and saw off before finishing the back without the waste of needing a lump to hold in the chuck so keeps the number of bar ends to a minimum. Or simply mean less stick out when working on longer parts.

I hope you are all ready for the flood of posts from people having problems parting off these larger bars in their lighweight machines

[Mike PooleParticipant @mikepoole82104]

The job is sure to come along along that is too big for whatever bore you have, a fixed steady can be very useful and for those of us with a small bore Myford it is near essential. It’s worth getting familiar with using a steady before the job comes along that needs it.

Mike

[not done it yetParticipant @notdoneityet]

I’m with Mike on this one. My spindle will just pass 26mm and so a one inch bar will just go through – if straight. It’s only working on the end that is a problem – usually got over with centre support and a small area turned (depending on the bar) and then resort to the fixed steady. Shifting the steady is likely as good as a 3 jaw (for concentricity) or setting up with a 4 jaw?

[egaParticipant @ega]

To be useful a 38mm bore would require something like a (heavy) 8" 3J chuck.
