I used springs ( approx 2.5 mm diam and slightly conical). I think I purchased them through Amazon.Nicely done Bryan
Just curious did you drill the hole for the refill just deep enough for the refill or enough for a refill and a spring? If you installed a spring with the refill would you share you source for the spring? I have been toying with the idea of trying a kitless pen but don't really what to do a fountain pen.
I drill a hole in the cap slightly smaller than the hole in the clip and thread it. Then I make a finial to fit. Thread the finial and screw it all together.Looks good mate. I also like the cap to body transition.
How have you attached the clip ?
