Experiments in moving gantry design (Al, steel & epoxy granite)

[Bongodrummer]

Hi All,
So a long time ago I started making a weird gantry. Thought some might get a kick from seeing how it went together.
It's a composite aluminium, steel and epoxy-granite beam, with cast Al endplates.



The machine's not really finished yet so loads more testing is needed.
So far it's looking good

PS I could really do with some advice about ballscrew protecting for this setup. I have bodged up a wiper for the rotating ball nuts of the long axis, using a glue gun 'casting type method...But it's very temporary. Am thinking the way forward will be to cover the whole thing, but how?

Nice result! I'm keen to see more cutting results

Thank's Pippin, yeah I need to spend some time sealing up all the ballscrews etc before I dare do much more cutting, of metals at least...
