Dear All, I am currently building a wooden piece of sculpture and am beginning to look to make it out of metal - principally Aluminium. The question I have is, how difficult is a large ellipse to draw/cut out of the above material e.g. Would an engineer have to buy specialised equipment (very large ellipse guides?) and also is the process of making stuff like this costly to do as I would like an engineering company to do most of the work. I know that a high degree of precision costs more but my project doesn't need that much. Thankyou for any advice. Sorry for the large post.
Simon.
