A deep blue pen in chrome clip and nib. Completed after a struggle of sorts! Generally happy with the finished pen. At 150 mm long and 16 mm diam at centre, this is a bit of a larger sized pen.
The poly-ester resin blank was brittle at thin scantlings- the barrel threads sharp edges broke off at places , will need to make smooth when I get some time later.The section threaded part broke off while drilling, so made a brass coupler. That apart, feeling generally happy with the way the pen turned out.Schmidt size 6 fine nib unit and converter.
This material is new to me.Very hard and brittle.But I found out how to work with it- spray water and keep it wet. once cold it is strong like steel, But if allowed to be heated it melt like jelly and rupture, that too all of a sudden. I used a tool that I reserve for stainless steel and other hard material. Ordinary tools get blunted soon and large chips break off. Wood working chisels if used need to to be razor sharp.The opposite end of the spectrum is the obedient ebonite'!
