If some one is paid one dollar per hour, dont hold him too accountable for bad work.

Depends upon what that dollar is worth locally in a physical sence, what we may see as cheap may well be a fortune to others.

Hi Tony,
 
not 'Armchair Lawyers' just people who understand their consumer rights instead of the sheep who follow the flock when told to by suppliers and manufacturers. 
 
Best regards

Hi All,
             as a Ps to my earlier post on this thread, the only modification that I did to the GH750 was about a year after purchase I did away with the single phase motor and installed a 3Hp 3 phase Siemens motor driven by a Eurotherm 650 drive.
                                                             Regards,
                                                   Raymond.

 Hi Terry -
 
...whatever. 
 
However, as I pointed out, there is a world of difference between understanding your rights and being able to exert those rights in an effective way.
 
Refards,
Tony

Tony,
 
You are wasting your breath here. I have already been through all the stuff you have said.
 
You are better off doing something productive.

Tony,
 
If I am right, that means you are buying the rounds at the bar...especially considering that I have to save the pennies for an impending court case
 
Terry,
 
I am still joking. Lifes too short for this kind of carry on....especially considering that John S, Tony, I and some others do not really need to be fighting WARCOs battles.
 
Come to think of it, we now even have a belated confirmation from the original contributor that it wasnt really about a battle in the first place!
 
What a bunch of  wonderful  people we all are!

She should have been in there with him, saved a lot of bother.

1. No one has "a reasonable expectation' that a light bulb lasts for ever but they would have 'a reasonable expectation' that a lathe would last longer than a light bulb. A bulb in most peoples minds is a consumable. A lathe is not.
 
2. No one is suggesting that any legal actions are necessary. The discussion, I thought, was about the underlying principles.
 
I agree with TerryD. We get the service we deserve. If the customer has a legitimate complaint, whether he can enforce it with any tenacity is neither here nor there. As a point of principle, the dealer should attend to the complaint rather than use the difficulty to avoid a moral responsibility.

I notice in this month's MEW an article that stated, many machinery dealers refuse to buy second-hand imports but are still are exporting quality used British, Continental and American machines to the Far East.
Wouldn't that be ironic if those Far Eastern chummies are using our stuff to make their stuff, (castings excluded)

Len,
Probably to melt them down.
Because of foreign investment prior to the hickup with the economy China has more than enough funds to buy new.
 
Last time I was over there and saw one of the plants they had rows and rows of new CNC with China Fadal on them, they even make their own plant.
 
This is an except for a Bloomberg finance page only this weel on Fanuc, the Japanes machine tool controller.
 
"Foxconn, the Apple supplier  buys 800 programmable Robodrills from Fanuc every month -- for about $62,000 each -- to make the stainless steel band that wraps around the iPhone. "
 
From Terryd

Dear John S,
 
I suppose you are one of those who moan about the nanny state and then moan when every mile of road in the UK is not gritted within the first 10 minutes after it snows and never carries emergency equipment or warm clothing in the car in winter. Expecting the emergency services to be there to aid you within a few minutes if you break down."
 
Yes I do moan about the nanny state, when teachers have a 50 page book to read about how to treat pupils and another 50 page book [ no joke this is true ] on bullying.
They can't play conkers in the playground and some schools have even banned running in case one of the Herberts slips.
 
Don't get me started on H&S, we have more to fear from that than any of the unions in the 60's and 70's 
 
Snow ? what's that ? had about 2" of decent frost this morning , last decent snow I remember was prior to 1990 when we sold the truck garage. 19 years of being dragged out by the police when everyone else was tucked up nice and warm to travel the wrong way down closed motorways in 8 foot visibility when we had 10 feet of bonnet in front of us to pull some poor bastard [ expletive deleted but it means someone who's parentage is in doubt ] who has crammed a 38 tonner into the back of a steel lorry.
 
No silly "Oh dear my fan belt has broken" but sit there waiting whilst the ambulance and fire crew cut what's left of some poor sod out before we can get chains on what's left.
 
I don't drive a car, I prefer a van, suits what I do far more. It carries enough warm clothing for everyone who can travel in it, a trolly jack - hate those bent bits of tin you get with nannymobiles and even a 1 tonne folding crane - just in case.
 
If I do have to call the RAC out and it has happened I must admit I sit and wait because I have a deep regards for the work they do and how idiots treat them having been roughly in the same boat. Fortunately we didn't have to deal with the great unwashed public.

Got to admit a trollyjack cant be beaten.
Got fed up of bashing my knuckles on the kerb and roadway years ago with those scissorjack things.
Slip it under and up goes le car, a doddle,  job sorted.

This thread started on the subject of CHINESE LATHES ETC. and shortcomings therein.
Mine has a wobbly top-slide: take it off, clean everything carefully, re-assemble and start cutting again - within a few minutes there is discernible deflection at the tool tip!
 
I saw an advert in an American magazine (American Machinist ?) for a 4-bolt anchor plate for the top-slide (replacing the 'as issued' 2-bolt system. Allegedly this obviates tool-tip deflection, but at some cost! 
 
Has anyone experience of this? Or comment to offer, please?

 You don't mention what size lathe you have, but earlier today I came across instructions for making a 4 bolt anchor plate for a 9x20 Chinese lathe:  4 Bolt compound clamp for 9x20 lathe

Eric,
Do you need a top slide for everyday work ?
 
No I'm not joking, I have taken the top slides off the two lathes I use the most and stored them in the lathe cupboard.
They have been replaced by large chunks of steel that hold the quick change tool post.
Rigidity for me on everyday straight turning jobs is worth far more than the odd small taper I need to do  just a few times per year.
 
When I need to use the top slide it's in the cupboard with a sharp tool in the original 4 way holder, so just two studs and nuts to undo and swap over.

John S,
 
That's a brilliant suggestion.
 
In all my 60+ years of lathe-work, I have never even heard of it.
 
Would you also add for beginners, that a calibrated hand-wheel on the end of the main leadscrew would be useful under these circumstances?

John how do you deal with say turning a simple shouldered bush does your carrage handwheel have the divisions to feed in fine enough increments to get the correct step?
 
At best mine is calibrated with 0.050 increments or are you using a DRO?

One lathe has a calibrated hand wheel on the apron, marked in 1/2mm increments and it's possible to halve these by eye so that 1/4 of a mill or 10 thou in old money.
Other lathe has provision for the hand wheel but it's not fitted so that's down to working with a 6" rule.
Again you gen get to 10 thou without a problem.
 
For 90% of the work I do this is fine enough, if I need to work closer I tend to go further and then face to the dead length.
 
A calibrated hand wheel will help for some but the only lathe I ever had one fitted, a ML7, because it meant engaging the 1/2 nuts to use I never got into the habit of using it, however not all people work the same way.
 
One lathe has the older type BW Electronics DRO where it pulls a wire off an encoder drum, the cross slide is still connected but the carriage isn't. To be honest I don't find it as accurate as the dials.
 
The other lathe that's in constant daily use has a glass scale DRO on the cross slide but no carriage scale because I don't need it.
Even on the cross slide I only use the DRO to get close and micrometers and the dial for final cutting.
Most of my diameter work is close, bearing fits to a couple of tenths and the lathe is good enough to get this on dials alone.
