Thanks for the reply irving2008 (sorry about the sarcasm couldnt resist) no harm meant.

1, The peices i need to make are roughly 4" dia and have a number of 5 mm holes drilled in a pattern and made out of A4 size Perspex sheet in a range of thicknesses (2mm to 10mm). The circuit board is the same size but i would like to engrave it rather than ecthing and drill the holes at the same time if possible.

2, I'm only talking about small quantities to start with. something i can set up and leave running and only have to change the cutters for profile/holes.

3, My budget is mostly set by the wife, when she starts noticing things turning up in the post is when i usely stop lol. As long as its not thousands its ok as i plan on doing the work myself so just parts and a plan.

4, I've spent the last 20 years making/Assy aircraft i.e VC10's, nimrod, Bae 146 etc. I also have a workshop i rent out that is fairly well equipped even has an english wheel which i built from plans.

5, I have some knowledge of electronics but not an expert by any means but i can put together most things so yes i would rather build the controller if plans are avalible to cut costs but i wouldnt want to design and build for scratch if that makes sence.

I would also like to cut sheet metal brackets out on it out of ali up to say 16g.
