As a very extreme example, pick up that piece of 50 x 50 x 7m long box section Jazz mentioned, in the middle, and it will bend and wobble like a bendy wobbly thing !

Come on.!! . . . Do the same with an 8x4 sheet.!! Give it to Rolf Harris and he'll play you a tune.!!!

Get a grip man it's all about design and bracing.! With MDF/WOOD it means more bracing, much more to get near steel.

I have worked both materials for years and have equipment to use both and if I could build just has strong, accurate, reliable and cheaper machine from wood then I would. I can't simple has that.!!

Sorry, I missed this one.

I completely agree :)

I know ... and you know ... , but some people might be inclined to think steel is just rigid.
