How I did my vault?
First, I made two columns with four sugar cubes were.
Then I cut the sugar cubes on one side, so that they became wedged.
At first one would make about 10 pieces, and maybe by chance some of them would be similar.
For one would do couple.
But you had to adjust a little.
Many, including me, tried to make sugar couples directly, but it was not so good.
They cut more and more, and sugar pieces were very small.
This meant that the vault was small.
Sockerbit number five would be thickest, number four narrower etc.
Until you got to the middle of the stone would grind on both sides.
I glued them together and let them dry, but people broke vaults.
My broke down twice.
Then I glued the sugar cubes on the bottom stones, one front and one rear.
So it would stand steady.
I have printed board into pieces more, for the arch the back stack rocks up a few millimeters.
We took turns wiping tables.
It was fun, but a little tough.
I think I should be a little more efficient and show more respect to the work, next time.
The bad thing was that my hands became quite messy, but outside it was all good.
I finished in about three to four lessons.
How Vault works?
An archway has a bulbous surface of such
The arch is built of wedge-shaped blocks.
The stones are pressed against each other and get a bearing strength.
How not to roof collapses.
The first stone at the beginning of the arch is called drop cap stone (on both sides).
The distance between the drop cap rocks is called span.
Vault highest point called the crown.
The length between the skull and the span called pilhöjd.
It supporting the vault called pay.
Between the vault and vederlagen are imposten.
The actual place where the vault is on (imposten, solid surface from the vault) is called drop caps.
The stone in the middle is called the keystone.
Vault outer part is called the arch back.
