Well, this is what I did… my CNC machine… It has a cutting area of A3 times 10 cm in depth. The only drawbacks are that it is very noisy, produces lots of dust and it is really sloooooow…. So I am in the process of upgrading it with a holding case to reduce noise and dust and with new threaded rods that are supported on both ends, not just at the motor end as they were.
To the video and some links in this post I add now some pictures:
An Idle Mind... 
I am going to try and build one myself very soon. Have spent about 3 weeks researching and am dying to try this out.
Thank you for posting on the subject.
I like the way you used the dremel attachment. I think that was a great idea!
Thanks, I am glad you like it. I hope to restart regular updating of the blog sometime soon.
If you finally get to build your own I do really recommend the Rockcilff plans, they are cheap and you get access to a great community of people who are willing to help! (link on the right pane of the blog!)
