Creating corners with foam board

Today we praticed creating accuate and neat square corners with foam board the tools we used included;

• a cutting mat
• a scalpel with a sharp blade
• a metal ruler
• an engineer's square
• pva glue

Firstly we neatened up any messy edges of the foam board by placing it against the engineer's square and putting the metal ruler up against it. Then moving away the engineer's square while holding the ruler firmly in place. A scalpel was then used to cut along the edge of the ruler in one motion.

This method was repeated until we had successfully cut two small pieces of foam board to the same size.

We measured the thickness of the foamboard and measured this distance in from the edge of one of the pieces. Using the scalpel we applied the same method as before to the length measured, this time however we only cut through the first layer of card and the foam leaving the card on the opposite side intact. It is important not to press too hard and damage the card on the bottom.

Once this had been completed to an acceptable standard, we peeled away the top layer of card.

 

A ruler was then used to peel away the rest of the foam leaving just the bottom layer of card.

A small amount of PVA glue was applied to the edge and the two pieces of foam board were attached using the engineer's square to ensure the corner was square.

Once dry, two strips of thin card were cut to the same thickness as the foamboard and each was finished with a 45 degree angle. These were glued to the top of the piece to cover the foam that was visible.
