Sorry Ian, As usual we Australians forget our neighbour in such matters. For anyone interested I reside in tropical Queensland. Regards Paul.

A little surprised to hear of the excessive wear on the changewheels. Did you ascertain the cause, is belt tension critical or some such? I have seen one mention of speed board failing in a Wabeco mill and note your problem, makes me a little concerned about their electronics. Once we go variable speed with electronics we are forever dependent on the manufacturer for backup.  How do you rate service regarding warranty issues. I note your comment regarding the 2400 and came to the same conclusion by sitting in front of a metre rule and approximating the reach to the hand wheel etc.  I don't see a need for the variable feed as fitted to the 3000, however would like to know if you find the single feed rate in any way limiting as such metals as silver steel and brass would normally be machined with different feeds and speeds. Have you found any issue with rigidity and finish with a heavy cut with the carriage well away from the headstock. Any further opinions and observations regarding machining with this lathe would be very welcome. My sincere thanks for your input, Paul.

Paul,

I think the problem with the change wheel bush is detail design - the mounting pin has an axial grease hole feeding a radial hole and an axial groove to spread the grease along the bush length.  The edge of the groove is sharp and I think just wore away the bush although the factory would probably claim the belt tension was too tight.  I remade the bush from a harder material, dressed the edge of the groove and have not had a repeat of the problem.

The factory support is typically German - gruff and unhelpful but the dealer support has been excellent, the factory was no help on the hunting issue so we replaced the speed controller board first which seemed a partial cure but the real problem I think was the speed sensor on the end of the motor - when we changed the motor (the sensor is integral) the problem was eliminated entirely.

I haven't found the single feed rate a problem but I think with heavy cuts you can notice the lack of rigidity of the design compared to a more conventional lathe bed - have you considered the 6000 series as an alternative?

Simon.

There is a Yahoo user group run by MDA precision that might be worth visiting for some alternative viewpoints - it's not terribly active so don't expect a lightening response ;-)

I have tried Model Engineer forum without success, and hope there might be a user prepared to comment on them. I am considering the 2000 for small model components and will not be wanting to do any large work. I appreciate an accurate machine and the FEEL of a quality item hence prepared to consider paying the premium in price for these qualities. I live in the antipodes,a long way from a Wabeco showroom, and want to verify from a user that these machines are what they appear to be, (or otherwise). In a nutshell Pros & Cons. Paul Gough

I'm gonna buy a WABECO D2000 to build small precision things, the diameter of the TEFLON rods is only 3/8" but the accuracy should be between 0.02 to 0.05mm. what do you think about the WABECO D2000? Thanks
