I built a simple out-feed support for my Ridgid TS3650 table saw back in 2007. It is made of some poor quality paint grade maple ply that I got from a local home centre. I say it’s poor quality because the face veneers are de-laminating in places, and it had an incredible number of voids.
While routing the slots on the fixed part, I actually ran the router right through a screw that was holding the piano hinge down. I was completely unaware that I’d hit it until I saw the newly flush-trimmed screw. FORTUNATELY, the router bit survived – I guess the steel in that screw was really soft.
