 Re: Round backlit sign
round shapes cand be cut using a tool called cnc router...like a computer controlled jigsaw (but not quite).
two weeks ago, faced with a similar problem, i used a vinyl template to trace the shape down on a pvc foam board (it was an elipse) and then i used a jigsaw to contour cut it.
some sand paper is necesary to smooth out the rough surfaces.
maybe that helps.
later edit - 6 foot in diameter...thats big...but i observed that some big signs are made by pieces... |
