Cheers fellas.

I use WD40 on my manual mill but after a while it leaves a sludgy swarfy mess in the T grooves which are a pain to clean. I wanted to avoid this on CNC if poss so hoped air would help.

I have a large compressor but its in shed 2 and shed 1 with the CNC won't fit it in :-)
I'll try a combination of the small air supply and WD40 and see how I get on.

cheers fellas,
