I'm really giving some thought to just mounting four long tracks down the top of the bench and to heck with dogs altogether. You could mount clamping jigs for bending, make all sorts of planing stops, have mounting points for accessory tops.... the list goes on. Sure, there is the issue of the errant chisel strike, but I always use a sacrificial piece under my work anyway. I would route it a bit lower than the top so you could still flatten or refresh the top a few times before you had to redo the track. It would make the top very versatile.
Imagine that T-track was invented in Roubo's lifetime. I bet he would think it was the greatest thing. What are your thoughts?
