Thanks, but I'm just collecting the gleanings of a long discussion on
T3D with inputs from a number of us.  Bob conned me into doing the
summary.  If it is a great article, it is a testimony to all the
contributers, including yourself.  Dr. T's editing suggestions were
also a great help.

Well, I did consider it, because I'm thinking about setting it up.  But
then I'm not sure of really the alignment technique etc. and couldn't
come up with a good reference.

The brief description that you provided though is probably appropriate
and your URL refence pointing to the basic collimator description.

Since you have already cobbled one up, I guess the technique is
appropriate.
