Knoba, Like I said I just love this thing and will be making one soon but realized you had a 17.8885mm spherical radius for your optics...how on earth did you determine that let a lone make it? I'll have to hunt for a tin though! :lol:
A really good and unexpensive idea !http://smileys.sur-la-toile.com/repo...prosterne2.gif
