Hello Brian,

One of the questions about the DualVee track is length. We are thinking of building a CNC table with DualVee as the precision track, but the lengths are somewhat shorter than what we were considering. Can these be joined together at the ends seamlessly, to make a track of, say, 60 inches long for example, that does not have a "bump" at the seam? (We'd prefer to use a single length to avoid this altogether)

We also note that the track offered is undrilled for mounting. Assuming we have good fabrication equipment and can hold good dimensional tolerances, are there any issues we should beware of when drilling mounting holes?

I'd heard or read somewhere that DualVee was self-cleaning (to a point). Does this effect come about from the different rolling diameters of the bearings as they rotate down the track, creating a 'wiping' action? Our concern here is dust contamination as the machine is being used causing damage to the bearings or tracks.

Lastly, for the carbon steel tracks, would oiling (like a lathe way might be oiled) be a good practice for corrosion protection?
