After spending more time with the table extension and Felder mounting bars, I'm realizing that:
-- If I flip the mounting bars "upside down" so the fasteners are closer to the top of the bar,
-- Use a smaller diameter spacer (stock is 20mm in diameter, I can can get on McMaster in 16mm diameter)
-- The aluminum table extensions should just work, where I could mount it anywhere on the bar without worrying about interacting with the mounting bolts.?
I'm still curious about the "standard" offset from the table surface to the top of the bar on Felder machines where the F-rail is integrated/milled into the table surface.....?
