Does anyone see an issue with this design? It raises the stationary rails right up to the bottom of the gantry beam. If the stationary parts are sufficiently rigid this design seems to:
Eliminate racking that could occur on a gantry.
Reduce the lever/moment arm that could amplify any slop in the linear bearings.
Eliminate the somewhat complex gantry post and its need for lots of bracing.
Raises the slides away from sawdust & aluminum chips.
Provides the ability to slide in stock from any direction.
The single point connections of the top rails would allow adjustment to a lower tolerance base frame.
