I thought I might show off a few of the kitless clickers that I make in this sub-forum since they might get some love here! I'm a fountain pen noob and have just started using one myself and I have made 4 kitless fountain pens. However, I find click pens the most useful and most of the people I know do as well, so I make quite a few kitless clickers.
They use a Schmidt clicker which is super smooth and (dare I say) indestructable. They are all metal in construction. The nose cones and adapter rings are turned by me on my metal lathe using stainless steel, aluminum and brass.
The first pen is sapphire Sheaffer cebloplast with stainless steel.
The second is vintage cellulose acetate and aluminum.
The third is Flexigran and stainless.
The fourth is vintage casein and stainless.
The fifth is Flexigran and brass.
The sixth is conway stewart red stardust and stainless.
