Week 9 - Tools, Equipment & Model Materials
House Components
The smaller components where created out of 1mm perspex. This is alot easier to work with, particularly cutting. Each component was created out of perspex, but in hindsight, it may have been better to use white styrene for the top and bottom. I can still clad the top and bottom with styrene, but it means more thickness.
The split pitch roof proved quite difficult to cut from the 2mm perspex. The first and second attempt left poorly defined angles. It was suggested that instead of trying to scribe and snap the angles, to use the belt sander to sand away the excess, leaving a far cleaner and more accurate cut.
The angles are lightly scribed onto the perspex. Running over the lines with a pencil before cutting will make them more visible, particularly if a sacrifisal piece of foamex is placed beneath whilst sanding.

Week 8 - Tools , Equipment & Model Materials
Perspex and Styrene House
Today I started construction of the house. Having already completed the sketch model in card, I already have the dimensions worked out, however because I'll be using a selection of materials extra planning will be needed. The main body of the house will be made from 2mm clear Perspex. this will then be clad with 1mm white Styrene.
Perspex
Available of thicknesses, colours, effects and textures.
Can be hard to cut, depending on thickness, with a scalpel but can also be cut with the band saw or circular saw.
Can be polished, sprayed with cellulose or enamal paints.
Can be bonded with Dichlo, Solvent Free glues, Superglue, Uhu, Contact adhesive and tape.
Can be bonded to card, styrene, perspex, foamex, cork and blue foam.
Same principles for measuring and cutting stryene can be used for perspex.
A scoring blade can be created by filing a hook into the back of a blunted blade.
This can then be dragged across the perspex several times creating a break line. The break is quite sharp with this thickness, but for smaller or thicker piece the Vargas Saw can be used.
The basic shape of the house begins to take shape.
