Hi Rod,
I have used a number of cad programs but now use Rhino 3d for nearly all my cad drawings. It is a true 3d package but more than capable in 2d as well. It is very intuitive to learn also and the interface does not change much from upgrade to upgrade. If you use a MAC there is a free downloadable version available at the moment from the Rhino website.

Also I have a CNC router. I can cut the bits for your scope at very reasonable cost!

Regards,

Bruce
