Hardwood CNC from wood on a budget, Possible?

[Sven]

When Isombard Kingdom Brunel proposed to build a ship out of iron, everyone said that would be ridiculous. It is common knowlege that iron does not float.

I feel that some similar reasoning is going on in most of the replies here.

Have any of the poster saying that wood will not work actually tried building a good router from wood?
I've been working on one for quite some time and I feel that it should be possible to get a wooden machine to work aluminium.

But it is not the easiest route to take.
Then again, people suggesting to go with steel also say it is "easier" because they are used to working with steel. But OP is used to wood.

I think that if you want to build a good machine from wood, this is what you need to do:
- Build a torsion box for both the bed and the gantry, at least 25 cm width for the gantry
- Use Bamboo or mahogany marine plywood
- apply epoxy to the sheets before working it, making sure no excess builds up on surfaces
- apply epoxy to the edges after cutting and during assembly
- use a biljard table as a flat surface for glueing the torsion boxes

All of this is not "easy" nor "cheap" but for a wooden person may be easier than going with steel...
