I couldn't find my old homemade hotwire cutter. (an old battery charger, a block of wood, two copper pipes, and a guitar string worked just fine for many moons...)
This is a small investment that will save many, many, hours of cutting balsa ribs, or paying for the laser cutting etc...
I have to say, it's a beautiful little tool that I should've bought 30 years ago.
The wires it uses can be bent to shape. A small Vee profile around the perimeter of a rib might do well to hold the cabosil/milled fibre goo in place during assembly.
What you see in the photos is the aluminum cutting template in white and the foam rib in blue.
I first printed paper templates to scale and later transfered the paper template to the aluminum shown here.
Here's a tip - check your yellow pages for custom eavestrough - they buy aluminum sheet stock by the roll...
