Überhorn Project Update 3:

In our last update, we talked about our ideas and plans to build a draw bench in order to create a body tube for the saxophone we are designing. To re-cap, the plan is to make three or more different tapers for the body tube and then get a real player's perspective on how these tapers feel and respond. Our main question at this point is how many holes do we have to put in these tubes to really get a good idea of the intonation of that taper? That is, how close to making an actual saxophone will we have to be before we can figure it out?
We're not sure how this project will play out exactly, but whatever we need to do to get our answers is what we will do. Right now, we know we need three different tapered bodies to start with: one that we know (a copy of something else), one with less of a taper, and one with a greater taper. With this, we should be able to get an idea of what the next step will be. And no, I'm not going to tell you which instrument taper we copied for our first mandrel. Not yet anyway.

Now, the drawbench is built and the mandrels are being made. There was a little delay in making the mandrels for this project as well as some other projects at In order to speed up the process, we bought a large CNC lathe. This lathe makes mandrels like works of art with unfaltering precision.  Plus, it takes about the same amount of time to cut as toasting a piece of bread!

In this first video, you can see our draw bench and a demonstration of how it works.  It's a little difficult to tell, but somewhere in all that cutting fluid and whirling tooling is the first Sax ProShop body mandrel being made. I wish you could see it, it's the most beautiful thing I've ever seen.
