Cutting openings in thick styrene?

Now there's a man that knows how to make sense.   While we struggle along, he comes up with an answer.
I guess that's why he's everyone's uncle.

@Russ. I remember Art Curren either coming up with that .. or .. re-cycling it.

I have no idea when or where I first became aware of the idea but it wasn't from reading Art Curren's articles. I just hope it will work for a large 1:24 scale outdoor model. I guess a lot of bracing, maybe of aluminum to resist warp, could keep things rigid for several years. -- Russ

I don't know how well it will work on 1/8 styrene, but on thinner stock I have used a sheet metal nibbler (hand type) to cut openings, then file to final squareness.
