Must thank Geoff Andrews for the inspiration of this mod.
Probably the only thing I don't love about my darling Logan is the 'ancient tech' top slide, and I've been foraging endlessly for how best to bring it into 21c functionality. By Jove, I think you've done exactly what I was looking for!
I must say, I'm particularly impressed with the tapered swivel that looks like it will claw up every ounce of rigidity, while providing an incredibly flexible platform functionally.
Hats off to you Sir!!!
