Lurker emerging from the shadows...

Welcome to the forum Andy!

That looks like a comparatively very capable and rigid smaller machine, notwithstanding the weak spindle that you mention is a POS. Although I've yet to build a machine, it looks to me like you've done a lot of things right!

With luck you should at least be able to use this CNC to machine more accurate parts for your next improved CNC machine.

I can't see from your pics: To help make your linear rails on each axis co-planar, have you used self-levelling resin under the rails, or did you have the strips under the rails machined?

By clicking on your images I've somehow found your blog and then somehow found many images of various projects you've done. Thanks for the very enjoyable afternoon I had, browsing through a few of your other interesting projects, including the jet turbine engine!! You sure don't let things hold you back.

I look forward to seeing how your CNC machine performs, once you've finished the fiddley bits.

As an aside, please satisfy my curiosity about an earlier blog photo of yours: What on earth is the contraption that you've attached (probably temporarily) next to your pillar drill, belt driven from the top pulley of your drill?
