Final assembly

Today, Halloween, October 31, 2011, was the final day of assembly. Today on our cardboard planetarium we added our squares to the bottom of our dome to raise it. Then we ended up with a few larger gaps in the creases so Mrs. Anderson came up with a way to relocate rivets and fix these larger holes.We also brought in our projector and DVD player to prepare us on our awaiting spherical dome. -Reno Ward

Planning and building the base

We were so busy today trying to get our base built that the students forgot about blogging. No worries, Mrs. Anderson to the rescue.

Today the students began the process of building the base of the planetarium. We discussed different ways of attaching the base, but finally decided to measure the lengths of the last row of triangles, then to add three inch tabs on the top and two sides of the cardboard sheets. The base sections are close to being square units. We hope they will easily attach to the base of the triangles and be able to support the above structure. Crossing our fingers!

While we were trying to figure out the bases we dealt with collapsing sides on the planetarium. We finally resorted to sending two gentlemen into the dome to hold up the sides while we worked. We're not quite sure how putting the bases on the dome structure will work out. Our main goal will be to support the dome structure and try to lessen the tension on the rivets so they don't start popping out. It could be challenging. We will find out on Monday...

THE BUILDING BEGINS

Finally we get to start putting the planetarium together. We started by bringing all of the pieces to a different room so that we could set it up. We put the top together first because we wouldnt be able to reach the top of it after we got the base done. We had to have people stand in the middle of it and hold it up so that we could start building from the top down to the base of it. Some of the rivets started to pop out but not a big deal we got them all fixed. We got to the base of the dome today and now we have to figure out how to build the base. Currently there are desks inside and outside the dome holding it in place. Be sure to check out all of the pictures we took of today's progress. -Jessee Vasquez

Final product of the day. Students are feeling very accomplished!

All layers of the dome have been added and desks put in for support. We will build the base next class and add in the remaining triangles.

Final cutting and rivets.

     Today we are finishing up on our cutting, as we are reaching our goal numbers of each type of triangle. We have started punching holes in the sides of the triangles for the rivets. At the same time, we are installing the rivets into the A and C sides to make pentagons and hexagons respectively. However, due to testing in the room to which we would like to set up the dome, we are only able to make trapezoids instead of the hexagons for better storage practices.

Assembly Line Day 2

On the second day of our assembly line we have 5 groups: Two groups tracing templates onto the cardboard, one group of four cutting out the traced cardboad with razor knives, one group bending up the tabs on the cut cardboard, and one group punching holes for the rivets.

Assembly Line...

Today we broke into four groups and began tracing, cutting, and folding all the cardboard triangles. One group used a metal straight edge and held it against the paper to make accurate folds. Two groups are tracing the paper triangles onto the cardboard. The last group is using box cutters to cut out all of the triangles.

Plan C

Today we cut out the triangle prototypes for our dome. To make things a little bit easier Mrs. Anderson had her husband make the prototypes on his CAD program. We cut out the prototypes and taped them to a large piece of cardstock to make them more durable when using them as a guide to cut out the cardboard for our dome.

Plan B

On the second day of working on our planetarium we finished cutting out the triangular pieces to make the dome. When we switched triangles we realized everyone had something incorrect. About the end of class when the entire class was trying to fix their triangles, Mrs. Anderson called her husband a drafting teacher at Tech and asked him how we should fix the problem. His Idea was to print out templates on his drafting program so they will all be exact. Then we put away our supplies  to prepare for next class with the templates.
