Bruce, you asked about how the router is kept from lifting, and I wanted to get a picture to answer that. So here's how :
That door hinge pin a snugs into that horizontal hole in the router base. That's for attaching a fence, but it offered a solution to that concern, so I drilled a matching hole in the sled collar to allow the pin to slide in and hold it down. I can lift the sled holding onto the router only and it doesn't shift or wiggle.
I got the label printer out and made some labels.

I may do the rocker board over using pvc plywood. The holes in the edge are not as centered as I'd like, and it would look better.
The level helps keep it square on my non level bench.
I really should level the bench with shims or elevator bolts
