Hi Alex
In terms of constructing prototypes, I’ve found the most flexible and efficient technique so far (for me) is to draw up the templates in a drawing application, such as Corel Draw and then either:
- Print off the design on an A4 transparency and then cut out the gaps with a sharp Stanley knife and steel ruler, or
- Print off a mask outline on plain, white A4 paper and use strips of tape to create the mask, aligning the strips of tape to the printed out template.
I have used the magnetic tape out of an audio cassette and some 6mm tape from my wife’s sewing kit. This way, you only measure once at the drawing stage and don’t have to mark out the work.
Cheers
Dennis
