Had a request to make a clipless fountain pen in macadamia nut. The closed size is 140mm. Cap is 15.7mm OD at widest point, tapers to 13.5. Barrell is 13.7mm OD at widest point, tapers to 12.3mm. It has a #6 jowo. I used the 10X.75 double lead purchased in the group by for the section tenon and barrell insert. The cap and barrell are triple 12x.75. Any comments are welcomed. Thanks
