So a few weeks ago I took a course on building segmented pens at my local Woodcraft. The class was very good and we came away with 4 different types; Celtic Knot, Spiderweb, Spiral Staircase, and a small piece of a Herringbone (which I am not sure I will be doing again) The Celtic knot is really the only one that was a complete blank and I decided to give it a try this morning before I started in on the other pens I am planning to turn this afternoon and through the weekend. Unfortunately it did not make it…

I was warned by the instructor that segmented pens can be an issue when turning, so I was not entirely surprised. I am looking forward to putting knowledge i got for the class to work to and make a few more of these on my own. Hopefully the next ones will come out a bit better.

How these patterns are done is still a mystery to me. Can’t wait to learn about them one day.
Keep at it.

By the look of some of the marks on the wood there, it appears that you should sharpen your tools a bit. Especially when your turning these segmented blanks, you have to take light cuts with a very sharp tool.

I’ve made a bunch of these. The first few I made the same thing happened as you. You need to have good glue coverage and be patient and let it set. Also, the skew chisel makes for a nice clean slice through the two different woods. Just make sure it is sharp and take light cuts.

Thanks all for the comments, sharpening is still a point I am working on. As well as skew chisels.

Brandon, I have to agree with you I thought the process was very mysterious and highly difficult. The class made it very easy and I am going to be making up some of my own in the not to distant future. Maybe I will put together a quick blog about it. I am no expert but I can deliver the basic premise.

What type of glue was used? I love the concept of the segmented blanks, but haven’t had the guts to try it yet.

J, We used CA in the class since we wanted things to dry quickly. However the instructor noted that he generally uses wood glue for a longer harder cure. I really need to make another set here and try it out.
Celtic Knot one was actually, I think, the easiest one to make as you did not have to deal with a ton of little parts.
