User:JaisonR/Igloo/Igloo Attempt 2

My second attempt worked much like the first but each process was a bit smoother from practice. As you can see from the photos much of the steps followed were the same.

Problems addressed from attempt 1:
 * 1) Block to block fitting was sloppy
 * 2) Block top angle not cut.
 * 3) Playdough may not be able to handle this size scale.

Looking at issues from the first build I did better address the block to block fitting on their sides. It was during this attempt where I really learned how important it is to have a very small angle on each of the sides of the blocks. Looking at the successive pictures during construction you can see that the blocks fit together much more closely. While it is not perfect there is a vast improvement.

Unfortunately, my efforts came too late and the dome started to become unstable from the amount of holes in the walls as you can see further down.

Block top angle for each layer was worked on more but it was not enough to successfully build an igloo. Part of my problem is that I have to estimate everything and work without actual angles or numbers. This is something our group will have to work on. While the math for igloo construction is probably complex I will be the best way to proceed.

Lastly was the construction material not being able to handle the scale. I did think about this during the first attempt but there was too many other mistakes to change that variable as well. After another failure I am thinking that scale is a bit too large for the scale of my igloo. If I were to make it a bit smaller with the same size blocks it will probably be more stable. I will have to try this in my next attempt.

Summary of problems from attempt 2
 * 1) Block to block fitting needs a smaller angle
 * 2) Block top angle not steep enough.
 * 3) Playdough may not be able to handle this size scale.

Unfortunately, my second igloo tended to look more like a cylinder than a dome as well.


 * Again as a final safety note, I would like to point out collapse on the bottom right. Collapse for the second igloo was different from the first and part of the wall collapsed outward. Depending on size it would be best that no one be allowed within 5 feet of the igloo if it is unstable.
