If you're going to build a lathe, build a lathe.

Let the business admin lackies define the market.
Now if you meant *identify* a market, well, that's
another thing.

Any clue to start the project??


Well, I think you're in over your head. Think about
why you'd want to build a micro lathe... More
precision than existing big lathes? Sorry, pick
another door. To have precision, you need rigidity
and to have rigidity (assuming you're looking at
building a traditional lathe) you need mass and
lots of it.

There's lots of guys here that could help if they
thought they weren't doing your homework, so
think about these questions and get back to us:

1. What kind of material do you want to turn?
2. What's the swing?
3. What's the distance between centers?
4. What's the max and min spindle rpm?
