Hi there,

I have bought an 8x4 router machine that needed a good looking at, but now is running pretty good. Some of the bearings needed replacing. There is a video below. As you can see in the video the surface of the table is sh**y looking. So im going to build a new top surface using this one, to make it square.

In doing so I will have to drop the ball screw position, relative to the rails, by about 3 inches or so. Will this mess up the motion? Will the motor find it harder to push, will i see more jarring starts / stops?

I made a drawing of what im talking about. Figure 1 is where it is now, figure two is what im thinking about doing.



video of the machine. I've since ground the entire gantry back to bare aluminium and its starting to look pretty.
