here are a couple tools if you get serious about pen making i highly recommend. first is the woodpeckers mandrel, well made and very precise. the duck did a review on this. next is the woodpeckers pen reamer trimmers. i have the complete 13 piece set because ive done many different pen kits. they also have a 5 piece set or you can buy the reamers seperately. as with all woodpeckers tools, not cheap. but a good pen mill is worth every penny. ive destroyed many blanks with crappy trimmers. the mill has replaceable 4 sided carbide inserts. the duck did a review on this set. here is what i started with years ago. not the best way to trim a pen. if any of you want em just ask.
working with my hands is a joy,it gives me a sense of fulfillment,somthing so many seek and so few find.-SAM MALOOF.
