I know this is preaching to the converted but consider the following scenario. I purchase a new car. A few weeks later, I notice that the tyres are wearing badly on one side and take it back to the garage. "Ah!" says the representative, "It needs the tracking adjusted" "Why was it not adjusted correctly at the point of manufacture?" asks I. "And who is going to pay for new tyres?" "Ah!" says the rep, "Nowadays we wait to see if the customer has a problem and THEN try to fix it. Oh!, and tyres are consumables and not covered by the warranty. Sorry." I can assure you, the representative would spend some time extracting the logbook from a bodily orifice that would not normally be a home to said document. I believe the correct words are "fit for purpose" under the trades description act. Good luck, Steve Have you bought any software recently (naming no-one in particular). That's exactly what happens. They only test got major problems and leave customers to find the rest of the bugs.

Head of the machine isn't square to the fixed jaw of the vice. Post #2.

This thread lead me to check my milling machine new last year from Warco, a GH Universal,and I found that the y axis was out by about 5 thou. The x axis was also out, but this is adjustable so one cannot really complain about this axis. Anyway I shimmed the front of the column with a bit of 3 thou copper sheet, and now it is pretty good. I really cannot see why we should have to do this, but that's life. I did find that squaring up the x axis was quite a pain, as it depended which of the 3 bolts you did up first as to how it would move out of vertical.
I used a clock held in the chuck, onto the table, but I put a nice piece of plate glass on the table first so that the plunger didn't bob up and down in the tee slots, and had 230 mm between each of the 4 measurements, so its now about 1 thou out on 230 mm hopefully this would meet with the approval of fellow engineers?
best wishes

Spoken to Chester today (the bloke wasn't in yesterday) and have reached a positive answer! They are going to send someone out to sort the machine out, which I can't complain at Out of interest, do machines usually come with any form of calibration certificate in the model engineering "section"? DC

Hi Dan, My Warco lathe came with a set of calibration data so I presume they do the same for their milling machines.

It's worth asking them if there should be something, I think it's pretty fundamental on something like this. Clearly it hasn't been checked or they would have noticed a huge error like yours.

Hi Dan, glad to hear you have had a positive reply from you supplier, hope they resolve it for you. Like Roger states I also received a certificate with my Warco lathe with various measurements having been checked, I did my own survey upon installation and they appeared to confirm the readings stated. Regards Paul.

nothing wrong with Warco...my lathe and mill also came with certificates.....the only thing I'd like is a slower speed for the lathe...one day I may get around to resolving this and installing a DRO..

The only difference is mine has handles that I have to wind! Cheers David Hi David, Actually, my Lathe is manual, albeit with variable speed drive and 1 micron resolution scales which cost about half as much as the whole machine! The mill is a Denford manual mill that I converted myself at great expense. The Warco is rough and ready, and very cheap. The main thing is that they make them with lots of metal so they're very rigid compared to something like a Myford. They also have a 'Vee' bed so although they're not that desirable from a quality point of view, they are much more capable than many older machines. Hopefully the results speak for themselves.

On my Warco mill I changed the handles for reduction motors,on X and Z, z was a real pain before, having to go behind the machine to wind it up or down, now just throw a switch. one of the best mods that I have made.
best wishes

DC So... We arranged last week for an engineer to come out to repair the machine. The engineer was supposed to ring early on, but didn't so we rang Chester - Turns out that it hadn't been arranged at all and the machine has to be shipped back to Chester! What a farce... This is the second time it's been back too! I've got a good mind to keep it there and they can send my money back!! DC

Good luck, Steve . . . and the words you put into your letter (recorded of course) are . . . it has failed and is not fit for purpose as described, within the terms of the Sale of Goods Act 1979 (as amended by The Sale and Supply of Goods Act 1994 and The Sale and Supply of Goods to Consumers Regulations 2002).
