I’m close to ordering my first Shapeoko (SO3 XXL). After looking at some options, I think I’d prefer threaded inserts instead of T-track. I feel like a spoil board needs to be replaced every few months. Do you just unscrew all of your threaded insets and put them in the new spoil board?
My thought is if I put the threaded inserts just below the surface in the original spoil board, then mount a sacrificial piece of 1/2" MDF on top, and have the Shapeoko drill through holes in the 1/2" top spoil board that line up exactly with the holes in the original spoil board underneath. This way, any bolts that I use in the threaded inserts would just have to be a little bit longer so that they pass through the 1/2" top spoil board and then catch the threaded inserts underneath. Setting the threaded inserts below the top surface of the original spoil board should make it possible to machine the through holes without hitting an insert. Any thoughts on this?
