Rick: Thats a very hard question to answer. Every pen you make is a custom pen. Be it color, shape, finish, or design. I agree with "IPD", set up to do more than one pen at a time. If I am going to do more than one pen, I will cut, drill, glue, turn, finish, and put together all the pieces one step at a time. This keeps me from having to reset any of my machines more than once. After over 10 years of pen making, I can turn and finish about 5 pens in an hour. I can also spend 2-3 days just designing a pen on paper and maybe another week cutting and putting it together. A lot depends on the skill of the penmaker and the equipment he or she has to work with. I have a firm belief in a dedicated machine for each task so you don't have to move things around to compleat each step. Even though I have had years of woodworking and plenty of tools, I am floored by the skills of the people sending photos in of there work to this site!!!! Time relates to skill and talent. Skill and talent relates to time spent. A properly planned project will always take less time.
