Hi Chuck,

I got this project from Roy over at www.diycnc.co.uk so I don’t know what software he used sorry, I have updated the original post to correct a few things and I have also added a pdf as a technical document for the part, it shouldn't really be too hard to re-draw this part in your own favourite CAD program.

Will keep my eye out for your reply, would be cool to see you make this and use it on your machine!
