Another ‘ole!

Bizibilder has made another hole!  This one is only 2mm in diameter and is in the centre of this “false eyepiece”.  This is a device to aid basic collimating (lining up the optical components) of his telescope.  You look through the little hole, in order to keep your eye centered in the eyepiece holder,  and then line up the mirrors by twiddling some very awkward to reach screws and bolts!

Anyway it was fun to make on the lathe – the whole job was only about 20mins using a bit of old Aluminium bar.
