Thank you both for your comments.
@ VeroniQ, no i had not seen these, the blog is not something i usually look at, there is a gallery for people to show their work, this encourages others to share and enjoy, it also allows users to see what can be achieved.
@ bdfd, creating the machines and the roller door was painfully slow, as i wanted them to appear feasible as operable machines, whilst not replicating actual equipment, but i am glad i did.
Here is a Link to the project, as usual it is building only.
