Cardboard Telescope (part 4) 

for 2017 VBS Galactic Starveyors

Here is a look at the materials and tools I'll use.

I measured three panels and two strips: the panels' dimenstions were 26 by 12 inch, 24 by 10 and 22 by 11 inches.  The strips are each 2 by 24. 

I made sure that the ridges of the cardboard ran across the short length of the panels; that will make them easier for me to curl into a tub.

 

I cut them and scored them. I used a small board to score them; the width of the board made pressing down more comfortable. 

I wanted it to be a fairly round tube so I scored it a bunch of times.

I curled it all up so it would stay in the shape I wanted. 

I needed a 1 inch strip to glue the two ends together; put a line of hot glue on one side and pressed it to the inside of the tube. then ran a line of hot glue along the exposed edge and press the tub together.

I repeated that process to create the three tubs that will be the body of the telescope.

I cut a few random strips to act as spacers between the different sections.  I hot glued the two strips around the end of the smaller tub then put hot glue around the strip and pressed it into the larger tub.

The body of the telescope it assembled.  

Next I needed a mount to attach the telescope to the tripod.

I started with a 9 by 4 inch rectangle. The 9 inches will be curled into a tub and will fit in the hole in the top of the tripod head.

Now I needed supports to attach to the bottom of the telescope. The center of each support needed to be exactly half the length of the rectangle apart from each other so they would be directly apart from each other when the tub is curled, so for 9 inches they needed to be 4 1/2 inches part.

I measured 2 inches from the end then 4 1/2 inches from that.  Then I measured 1 inch from on each side of those marks. That made two risers that are 2 by 3 inches 

Now I measured up 7/8 of an inch on both insides of the tabs and drew a slanted line out to the top of the tab.  This will be the angle the telescope will face toward the stars.  I drew a two inch wide and four inch long angled support.

I cut two cardboard wide slots in the center of the two risers.

I cut the hole thing out, and I cut the two slanted supports from each other.

I scored the 9 by 4 inch section and between the risers and the supports.

When I curled the rectangle into a tub the risers tore so I cut a four braces and hot glued them to the inside of the risers.

I cut a 3 by 3 1/2 inch brace to hot glue inside the two slots I cut out of the risers.  I curved the top of this piece in case it came in contact with the telescope; it didn't.

I drew a 3 inch circle inside a 4 1/2 inch circle. Then I cut them both out and hot glued it to around the tub.

I balanced the body of the telescope on my finger to find its center of gravity, and marked it so I knew were to glue the mount.

So far so good.




 In the next and final step I'll put the eye piece, lenses and trim on.
