The article Alan posted is one I converted to PDF format from a few JPEG 
scans that Alan sent me.  Glad to hear it worked for you.

I have the earlier Eddie Butt article, and I'll try to convert that to PDF 
and post that as well.  It may have to wait until I get back from vacation 
in early June, however.  The Eddie Butt article has even less information 
about how to build one of these, but does talk about various design 
decisions, etc.

The only technical information mentioned on the prism is that it is a 60 
degree prism, and that a 45 degree prism doesn't work.
