ooh crossed posts....

I use wood too, and am very happy to make it not bend.

Others work with wood.

I was just trying to put forward the view, that steel isn't for everyone, and wood can do a very good job, after wood was being bashed as "no good"

different options for bearings too. Never tried CNCRP trucks, so can only go by C1's use of them. again , just saying there are alternatives, as John (Microcarve) will testify to with unsupported round rails and oilite bearings !

Even building a big machine in steel, isn't easy . the design needs to be right, or it will flex badly.

I guess I'm playing devils advocate for wood, and budget builds :)
