I've used a round-over router bit on it when I had to rip a piece. Lots of
flakes but it machines pretty easily and didn't seem to wear my bit any more
than wood would have. I also have a few scraps just in case I ever came up
with a use. I don't know about chairs, maybe if they had a wood frame and
the trex was used for the seating.

Has anyone else out there tried? What was the result? (I suspect dull
blades).
