making a astronomical sighting quadrant out of a protractor and a drinking straw

Owing to my hospitization and slow recovery rather a later post than originally intended

I  made this quadrant in 2007 but am now unable to find it or any of my other   made

kits  such as the Astrolabes, Moon phase dial and Nocturnal  at home   believed thrown out as just  bits of cardboard during my long absence

 

Tycho and Hevelius made many discoveries  with just such great  quadrants

 but here I made a simple  altitude instrument  reading to 90 degrees  and  consisting  of a  protractor  (see  template ) to which an ordinary  drinking straw was  fixed  horizoniclly as a sight  and  from which a plumb line   free weight  dangled on the end of  a string  tied through a hole  seen as a small circle  just above 0 degrees on the template

 Completed  the quadrant can be sighted on any astronomical object  and the altitude read off  on the scale  arc from the dangling plumb line

It of course  can   be tested like any  quadrant   by sighting on  Polaris   according to your latitude

 

 

all you need is

a   90 deg protractor  either  the old one from maths class  or print out the template and affix to hard card

a drinking straw

string  to attach weigh  falling to arc of quadrant

a weight or plumb bob
