I spent the day replacing the original MDF base on my XXL with 1" plywood, with some T-Track laid into it. I will cut some 3/4" MDF sacrificial boards to sit on top of the ply between the tracks.
I was having a lot of trouble with flex in the original base too, so have removed the screw-in feet, and the machine is now sitting on the long supports that sit under the base board. I will screw the board into the torsion box that I have the machine sitting on, to ensure there is no movement at all. I was getting around 0.8mm of flex before…
There were only 4 t-tracks available locally, so I’ve made do with them by cutting them into smaller pieces, it should work for 95% of what I need to hold down. I routed slots so they sit just below the surface, this means if I need to cut something quite thick I can remove the MDF and still be able to hold the timber down.
Comments welcome! anyone know if plywood will be more stable than MDF? I believe it’s less susceptible to moisture, but I have given it a few coats of lacquer to be sure.
Also tried my hand at a resin inlay in some Coasters, came out quite nicely!
