Further CAD development

 
 
 
CAD DEVELOPMENT

 
 
I've revised the design of my external former.  The former is now made from four interlocking pieces.  It will still be CNC machined. 
 
 
 In order to enable a feature to be applied to the face of the body of the speaker the former has to break apart.  This will ensure the former comes free from the concrete.  The feature will be added to the internal face.
 This method greatly improves the ease of assembly and disassembly during manufacture.  These pieces would ideally be made of plastic, however, for this demonstration I will use jelatong.  The former will be lined with thin plastic sheeting, this will ensure a smooth, flat finish.
