I have some Schmidt SKM-88 mechanisms that I got from Exotic Blanks a while back, which is serving as the basis for my reverse-engineering attempt at a kitless ballpoint. I need to work a few things out, though. Right now, it's just ideas in my head.Next up is a kitless ballpen. I use ballpens every day. My first choice would be a fountain pen but as I have at least 8 sitting in a drawer I really dont need to make any more.
But a ballpen could be interesting so I am going to give it a go. Watch this space.
Most if not all of my kitless pens I have to admit are turned on a metal lathe. I use the wood lathe for some bits but I mostly use a metal lathe.
