Paul, it takes me around 6 or 7 hours in acrylic with a clip for one pen, a bit less in series, without glue curing time. I prefer to measure twice and cut once, that takes a lot of time and could be sped up. I am getting better though, my first kitless took me three days!Roughly how long does it take you to make a kitless pen? I would love to have a go eventually if ever I have the time.
