While i'm gathering parts for a new build, i want to use the full 48" on my current "MDF" build. I have been looking at MD on *bay and these 2 sizes, it will be for my x axis

TR16x4D

TR12x6-P3D (2 start)



Jonathan if you read this will your bearing thingy majig work ok on any of these. I'm currently using it on the x with the 16x2 you sold me and it works ok, don't fully understand how it actually works but it does. Would you be able to make a couple of nuts for either of those rods if the bearing does
