lathe recommandation

[niner]

My micro-lathe (Sherline) is no longer working out for me, and I need something slightly bigger. Given the limited workshop space and location, I can only get something not much bigger than 100lb. I don't mind pay more for high quality tools. I have narrowed it down to two choice:

Micro Mark Mmicrolux 7x14: http://www.micromark.com/MICROLUX-7X14-MINI-LATHE,8176.html

or

Proxxon PD-400: http://www.proxxon.com/

I don't know a lot about machinery, so please your opinion. Thanks.

The microlux has a much bigger capacity and more versatility. You are in Boston, so will probably be usining inches as a base. The Proxxon is laid out in MM.

Accessories for the microlux are much easier to get, since they are the same basic design as Grizzley and HF use. The proxon chuck looks like its adapted from a woodworking model.

Since the Microlux will let you work on things that are 3 inches bigger diameter than the Proxxon, and about 5 inches longer. At some point that may make a difference.

The one thing people never mention when talking about small machines.... The bigger it is physically, the more room you have for tools, measuring, lighting, clamps, etc.

Hi Daniel, I'm actually more used to mm than inch system. The Proxxon PD-400 that I'm considering is 15.76" between center, and 6.7" swing, so sizewise they are more less the same.

But you have a very good point. Parts and accessories for Microlux are very easy to get. And a lot cheaper.

From my friend that owns the PD-400, I know it is a very precise, very high quality machine. I don't know if these chinese lathe can match, and maintain the precision.

What do you think?

My opinion;

A lathe will be as accurate as the operator can make it. I've never heard people complain that they need to replace the headstock bearings on a 7x10 class machine, and TIR at the spindle is generally fairly low ( for a machine that retails under $2000) .

The rest is in keeping within the design limits and keeping it adjusted.

Making the headstock parallel with the ways is not rocket science, and both my 7x10 and 7x12 were able to turn 6 inch spindles without excessive taper.

I do not check it often enough to ensure that it is still adjusted that way.
