a couple of years ago, i developed cast-type penrest.
this time, i started developing solid ebonite penrest.
the result of this project will look something like the picture below.
main materials can be seen below.
since color rods are limited in number, black ebonite will be produced in larger quantities.
the development is at initial stage, so i am getting equipments ready,
in the next posting i will show its further developed stage.
thank you.
