Artists' Pencil In A Home Cast Blank

[manojd]

This is my first mechanical pencil and that too kitless. I am using the Schmidt mechanism. The blank was in-house using polyester resin in a four color pour (red-green-blue-black).

 

I had a lot of fun doing it. The threads for the front section were a non-standard 0.8mm that I had to cut on the lathe. I had no mandrel (or bushings) for matching the barrel with the front section. So, this took a lot of measurements with trial and error for fitment. The click button was a joy to make, but I still need to practice knurling. The wall thickness for the button is less than 0.2mm. I have 11x0.75mm threads on the end cap.

Thanks Hari.

 

The front section has 10mm major diameter.

dear Manoj, perhaps a M10x0.75 tap could have done the job, the tap set is easily available in Mumbai, maybe at Pune too.
