Re: Cutting styrene sheet into narrow strips...

Thanks to you and everyone that suggested ways to do this.
I made a tool that uses a pair of razor blades (steel backing removed first) with a .020" styrene spacer between them. A 2" long piece of 1" wide by .032" thick brass strip, with three holes drilled in it to hold 4-40 screws, serves as the handle.
The blades and shim are assembled, the screws pushed through them and into the holes drilled in the handle. A 1/4" nut driver is used to tighten the nuts, and we have our tool.
I draw the tips of the blade at about a 30-degree angle along a steel straightedge across a sheet of .005" styrene, and can produce approximate .050" wide strips.
I tried making a similar tool without the spacer for .030" wide strips, but found that the blades flex too much for consistent width strips. Maybe a backing piece on the exposed side of the blades would help prevent blade flexing. But Evergreen makes .010" x .030" strips--I'll can live with the overthickness of these strips as the outside member of the Z's.
I had experimented with using a Fiskars "Eurpoean rotary paper trimmer"
for these strips, but found that paper strips of this width were hard to cut consistently with this tool, so did not progress to cutting styrene with it.
BTW, they make a nice diagonal cutter that isn't too expensive, and that I use as a parts trimmer and small diameter wire cutter--
