Please review this router gantry idea

Just had a quick look at pipe prices ! so what about making a fibreglass pipe with the mounting points incorporated ? and I've just remembered there's bendy plywood now so a pipe of any wall thickness could be laminated up. Now I'm not descending into the MDF gang but I think there may be enough strength in the plywood idea.

Fibreglass rules OK, I was contemplating this when i first started thinking about making a machine, i had a try @ Vacuum Infusion on a little project a couple of years ago and the casting was very rigid and i had the feeling it could be a good material for reducing vibration ?
