Do you mean on the web?  I do not know of anyplace other than in the ATMT
book by Mackintosh.  I do not have a scanner or  I would copy the page and
send it.  Perhaps someone could do that for you?

Subsequent work by Jose Sasian, who has developed much in the TCT field,
says that polishing in the toroid curve is not too difficult.  Issue 37 in
Telescope Making Magazine is an article by him on designing a Yolo, and
shows how to build the fixture for making the toroid, as well as testing
it. Issue 45 has an article by Mulherin, making & testing the toroid,
and collimation tips.

It seems that warping the secondary is not too popular.  I wonder, having
successfully made a flex mirror, if the secondary could be pulled with a
special pusher and puller cell.

Mr. Sasian was recently part of the Optical Sciences department of The
University of Arizona.

Good Luck

Is the harness to deform the Yolo secondary described in detail somewhere accessible?
