Long post:

I have made a lot of progress on the cradle and, although I may make some changes to the head stock design, I'm pleased with the results so far. Here's what I've done:

The 'bed' is made of 1x3 oak purchased from home Depot. the rails are 4' long with short spacers glued at each end:

A mortise is made by gluing in an 11" spacer 2 1/2 inches in front of the head stock spacer.

The head and tail stocks are made of the same 1x3 oak laminated with the middle board just under 2 1/2 inches longer than the shoulders to create a tenon that is just shy of the depth of the mortise. This allows the stock to be locked in place with a washered bolt.

The bottom of the tenon was drilled and a hardwood 1/4" threaded insert (ez-lock) was installed.

The allows the head stock to be removed of necessary (using a wrench), and the tail stock can slide along the bed.

A cabinet pull knob was tapped for 1/4" and a short length of screw inserted. This allows easier, tool-free adjustment of space between centers:
