Carl,
I've been looking at what may be a simple solution. A metric Framing
Square, A Plumb Bob, One of those Cheap Laser Levelers that put out a
Line rather than a spot on a surface. For instance the leveler shining from
500 mm on the short arm of the square to the other arm of the square

Hi,
check out Meade Autostar, it looks like something that could be easily

I am attaching my custom laser trigon, the image is
but 14k.
I use it for dials about one foot square with gnomons
of copper sheet. Errors creep in quickly as the dial
plate expands in size.
Alignment takes some time, and involves the rotational
axis being well aligned with the style, and
Hi Alexei,
I have built a lightweight laser trigon from a laser pointer and some
scraps of perspex. As well as producing hour lines and declination lines on
arbritrary surfaces, the trigon also has an attachment that allows it to
project analemmas about any hour line.
I have written up the

Some time ago I read on some website about a Laser Trigon - which was a
laser fitted onto an equatorial axis which I believe simulated the sun and
could be used for the projection of the sun rays on any surface.
However I have no idea where I saw this and would be grateful if someone
