Geoff thanks. I'd found some favorable comments about Chai yesterday.
Homann Designs looks like a useful resource.
I've not got to far on the cad/cam stuff yet. I need a major skill's upgrade to get to that part. Initially I think I'll use the Mach3 wizards to generate code pieces then put the bit's together as I need and look at Cad/Cam once I get the time.
