MEASURING MODEL

MEASURING ALUMINIUM SHEET SIZE :

Because of the Dome shape are too CONCAVE

It is impossible for aluminium sheet to bend into the whole shape

Therefore I have decided to do HALF of the the model in order for aluminium to bend into the shape

MEASURING :

Measured with a STRING in two dimension

Which could then flatten out and measure the LENGTH of the string

Then you could estimate the WIDTH + LENGTH of the aluminium

~

CUTTING SQUARE :

After MEASURING the length + width

Flatten out the MARK the estimate length on the aluminium sheet

Then CUT the Aluminium Sheet in the big cutting machine by measured mark

By PRESSING the foot step to cut

~

DEFINING SQUARE :

After CUTTING the Square

Shape could be DEFINED by marking Approximate Shape of the model

And cut with this TOOL

As a Big square are very DIFFICULT to work with
