If it's long, narrow bits of beech you have in mind, like guitar necks for example, then taking that entire fixed gantry and putting it on rails might let you build a machine with a very stiff Z axis, though you might need control software that can do auto-squaring on two axes at once.

Kit, that is next on the list. The design as been in the works for over a year but I keep scrapping it and starting again as I just can't make it work as I would like, but i think I've got it sussed now.

Edit: Oh and doesn't need dual-axis motor slaving as the screws are connected with belts and use just one motor.

Great minds eh? I realised about the belt drive about an hour after I wrote that. You can see the single motor in the pictures. I assume the long axis would be done the same.

For long thin work that's going to be a very solid design and with the option of a fourth axis up the middle would be the bees knees for fancy furniture legs and a myriad of similar stuff. With the right gantry design you might be able to achieve an unusually high Z axis lift without seriously sacrificing rigidity which would help with that kind of work.
