Ok, starting on what will be custom pen #4. This one will be my first wood one. Wood is Boxelder Burl, stabilized & dyed by myself. Sorry I missed the steps to get from the rounded blank to what is pictured below. I just decided to take pics and post my progress on this one. After rounding the blank, I measured what lengths I would need for both the cap and body portions. I left both a little long, so I can clean up the ends from the centers after shaping later. I then drilled out each section. I think I used 9/16" for the cap (drilled it almost 3 weeks ago, so I can't remember) and I used 11mm on the body. Based upon the measurements I've thus far been working with, I drilled the cap 66mm deep and the body 73mm deep. How deep I'll need to drill on other pens will always depend on the design. After that I turned some ebonite rod down to diameter to slide in, leaving it all a little long to give me something to trim up later. I made a shoulder for the body of the pen as I want a band of ebonite as an accent between the two halves of the pen. I then epoxied them in, currently in clamps. I'll let it sit in clamps for at least 24 hours, but more likely 48 hours. The epoxy I'm using - System Three T-88 - is the best epoxy I've used, but does have a long cure time.
