Here is an octagonal pen I finished, which I made from Conway Stewart “Azure” acrylic. It’s about 5” long, with 12.5mm cap threads. Clip is made from silver. The cap and barrel both have subtle tapers. It uses a jowo 6 nib.
They do not come any better than this pen John,there are so many wise and understanding pen turners who will be gobsmacked by your pen. Congratulation on using a decent mill and cutters with delicate blanks like these. So many thanks for sharing this with me,so far away but vitally interested and impressed.
