Default making the device.

and...following the previous topic.
I am already making the device.
which allows me to do the next piece. ( )
this piece is a cupped ellipse.

I hope in the next few days.
obtain the five parts needed.
to complete the elliptical reflector.
and get to do some tests.

I do not think in have problems in making the piece.
only mirrored Cheap place the inside surface to be difficult.
that's why following the advice of Mr Guy Grotke
and divide the total pieze in five parts.
that helpme to put a thin plate mirror.
