I have found the photos in your gallery, do you have any more (of the build)? ... I am just starting to collect some bits for the same machine you have built, but like you I am not going to use timber.

What material did you use to mount the racks on? also I assume you used Aluminium for the Y axis side plates, did you stick with David Steeles' bearing choices?

Oh and did you ?... Ummm ... did you also? ... I'll shut up now.
