    Default joining linear rail

    Hi guys, just wondering if anyone's had anything to do with joining linear rail. A friend of mine is designing a 6 metre long cnc router table but can't get hold of that length of 20 or 30 mm linear rail
    I don't know how the bearings would handle the butted up join. Not very well I would imagine.

    It would potentially be awkward but i would try something like milling the ends square and then scraping them dead flat and vertical, awkward thing to support on a surface plate but doable.

    You can order rails intended to be butted.

    Have to align them quite precisely of course.

    I wasn't aware of this. I'll tell my friend to follow up with the supplier.

    Why do you need a 6m long router? Just curious.

    A friend of mine is designing it for a client. I'll find out what he's doing with it if I can.
