Cardboard Telescope (part 5) the Lenses

Prop cardboard telescope

After this step the whole project will be ready for paint.





I like the thin transparent plastic from containers that spinach and danishes come in for the lenses.

I traced around the large end of the telescope ,made in part 4, then added four tabs and cut it out. 









I wondered if I painted stars and a planet on the inside of the lens if the children would be able to see them, so I tried it.






The eye piece began with a 9' x 4" rectangle of cardboard. I drew it, cut it, and scored it.





















I hot glued a narrow slice of cardboard on the inside and then glued it into a tub.

















I cut two discs the same diameter as the small end of the telescope that was created in part 4.  Then I cut holes in those discs so the tub I just made fit inside.









I glued both of those discs onto the end of the eye piece. 














Next, I put hot glue around the edges of both discs and fitted it into the telescope.












The paint had dried on the large lens so I folded the tabs put hot glue on them and fitted the lens to the end of the telescope.  


Then I hot glued a two inch wide strip around the end with a little bit of overhang.  This hid the tabs and gave it a finished look.







A look through the eye piece.   


Not bad.
















I attached a lens over the eye piece the same way I did with the wide end.












































Here is the finished eye piece lens.







I'll probably add a few rivets and knobs before painting, but here it is.
