Waiting for profiles. I will privide some examples, of not straight joint for sections.Thanks for the kind offer. I will see if I can get profiles of the parts I made, as opposed to the parts I designed.
Just an arbitrary example :
Section is elipse 1000x600, 2500mm length as base.
And by combinig it with other, more tapared and "bend" (tail section is not at centerline, but lower or upper)
We can get pleasent and intesting shapes. But you will need two molds, for each side. But - they could be cut from large eps block with no effort.
