After cutting the piece of exotic leather needed for this pen project, I skive the edges and center of the leather depending on the thickness. For me is important since this type of pen is a twist action pen. If the barrel ends up too thick, the twist action will either not work or will strip the interior connector and the pen's life will be short lived. Trust me!
I put the pen parts together and check the barrel & leather before I glue to make sure the fit is perfect! Once I am satisfied, I move on to glue up the leather onto the barrel tube. Stay tuned!
