laser cutter/engraver rebuild build log

[gavztheouch]

I have been thinking about how to lower and raise the cantilever gantry on the laser.

A couple of linear rails with a lead screw down the middle that can be turned via a hand wheel is one way. This would be locked off with a clamp of some sort. I am missing an easier and cheaper way of doing this.

If I went with profiled rails I could get away with using a set of second hand rails as accuracy is not too important.

Would it be worth contacting a local machine servicing company I imagine they must throw away any linear rails that need replaced?

I have a drum sander in the workshop now I think about it which does exactly what Im after here will take a look at that and see how its done.
