I sure do like the CNC as you've built it. The only small thing my "what if" mind worries about is that wood chips may land atop the side toothed rack and jam up the Y movement. When I'm cutting up and down the grain of hardwoods it is not unusual for large wood sections to split off before being chewed up by the router bit. Big enough to clog up the 2" hose of my dust collector.

In addition to holes for clamps cut into your tilting table section you may want to reinforce/stiffen that MDF panel. I've use furniture grade plywood for mine and they occasionally deflect/warp when clamping down boards that have their own warp or twist.

That photo looks like all the (good) parts from an abandoned profession exhibit. I've been at trade shows where company booths were made from just such parts, and left for scrapers for being too expensive to store and/or ship to the next exhibit.
