Thanks Neil, Linear Rails and Lead Screws have now been ordered.
For the routing side, it will be an experiment with a small Dremel type tool, not expecting it to be wonderful but an experiment to prove I can do it, I might then decide to make a larger more sturdier machine once I am happy. Likewise with the laser, once I have mastered the basics of engraving, I might upgrade to a CO2 laser cutter.
Thanks ever so much.
