Re: Newbie and Wooden Machines

Hi Peter,
Check out this website, it caters to homemade CNC
machines. Look at the machines in the left side window.

being a very strong mechanical engineer I am challenged by the design
of a suitable milling machine. I would like to build a three axis
machine capable of machining soft materials (wood, plastic etc) up to
say 500mm x 300mm x 100mm. There seem to be two options - buy a
manual machine and convert to CNC or fabricate a machine from MDF or
similar timber material. Having only limited workshop facilities the
idea of building something out of MDF appeals, but is it practical
and does it provide a workable machine ? What type of slideways
should I use, what type of lead screws can I use - the idea of using
ball raced double extension drawer runners and threaded rods appeals
but again is that workable ?.
