I really like those tracks and bearings. One though to consider though
is the fact that they must always be held down. The old WoodChuck just
rode on the top of the rails and had the tendency to ride up off the
wood if there was too big of a cut of if your blade got just a little
dull. The fix was to always hold your router and carriage down when you
made any cut. I feel this system would be the same unless you would add
a spring-loaded bearing underneath to keep in snugged onto the the upper
rail. Just something to think about if you are looking to incorporate
this into any modifications.

Hi Bill
It would be interesting to find who made the extrusion because I think
it is an off the shelf extrusion and somewhere in the back of my
memory I recall Andy Anderson prototype a CNC machine with this type
of extrusion profile although it never went into production. My memory
could be faulty by the way, but after 75 years of use what can I expect?
Cheers

Check this out possible legacy rail replacement what you all think.
slides easy and doesn’t look like there would be any saddle slop
type movement like in the legacy gets great for possible template
work and its modular so a mill as long as you want
