Default 20 Strand Sierra Helical Pen

Here's one I did a week or so back. It has 4 strands each of 5 different species of wood. The woods are walnut, maple, cherry, osage orange and redheart. The second photo shows one of the 5 blanks as cut. It has 18 helical segments. You're probably wondering why 18 segments instead of 20. The segments have been laser kerf compensated which moves the the laser cuts 1/2 kerf away from the design line on both sides of the segments. I use 0.007" when designing for kerf. When you take into account you have 18 cut lines the 0.007" starts to add up and you lose a couple of the segments as opposed to having a perfect cutter with no kerf. You also have to take into account the angle of the helix.

I'll probably not be sending these to SPS. My local wood turning club was having their annual tool and wood auction this past weekend. I made up and glued up 10 blanks or so to be added into the auction items. Knowing that my fellow turners in the group are pretty frugal, I decided if the auction amount didn't reach 40% of retail I would bid on them and buy them back. I was going to tell them if they wanted an item and wanted to keep me out of the auction just open up with 40% bid, I wasn't going to continue bidding once the 40% bid level was reached. I figured this would give those that wanted to try a $25 segmented blank for $10 the opportunity and the club would get a little money. The person running the auction suggested rather than me having to buy the blanks back to just put a 40% reserve price on them. As I stated they are frugal and I ended bringing the blanks home. Send me a private message and I can probably hook you up with some blanks.
