A few questions to start a DIY mini CNC

[purple_rob]

Many thanks for your input. Has made me think about what I actually want.

I would really like to start cheap and small. Mainly because I want to learn the build and software and do not have anything major I want to build.

Lets say I wanted to machine a relativly simple engine block from a hard resin about 50mm by 30mm.

What I need is a simple kit or list of parts, like a small DIY kit. I saw this

http://cgi.ebay.co.uk/3-AXIS-CNC-Rou...d=p3286.c0.m14

but its way out of my price range and too big.

I have a friend who works in an alloy supply company and has all kinds of tubes there. I was thinking about usings maybe alloy beams and roller bearings for the build. Its something I can get and already have.

Unless I can ebay or machine some cheap parts. I do have some old printer inside that has some really nice steel rods.

Any advance on the ideas :)
