THE TRAY
We got a big aluminian sheet.We decided to use wood to made a mould first. We cut the wood to a 100*100mm square shape.
We fond a column, trace it on the four conner of the square wood.
Then, David cut the wood.
It is perfectly mach with the column.
Then, we done for the wood mould. We can start to cut the aluminian.
We cut the aluminian into two 110*110 mm square sheets. We leave 10mm on the each side. So the aluminian is 10mm bigger than the wood mould. After we finish cuted the aluminian sheet, we sand it and make the edge more soomth.
Then, we start to hit the aluminian. I hold the aluminian and wood mould, David hit it. When we finish one tray, we do the same process to the other aluminian sheet. We use the same mould to make the two trays, so the trays will be the same size and curves.
