Backbore Comparisons

The table below provides comparisons of some of the more common backbores. They were obtained with a low tech method using pin gauges and a Vernier digital caliper.The data was then imported into an Excel spreadsheet and imported into RhinoCAD as a point cloud, from which the curves are drawn.

Although this is not a sophisticated method, the results are highly reproducible to about 1/1000 of an inch and are consistent when calibrated against known dimensions of Wedge backbores turned on a CNC lathe.

To see two backbores together find the first one along the top row and click on the X corresponding to the row for the backbore to which you wish to see it compared. The image will load without leaving the page.

"This new Wedge Mouthpiece came to me just at the right time. I'm the Second Horn player in the Calgary Philharmonic, and we had a Beethoven Festival coming up. You all know how the Second Horn plays everything, and Beethoven can be brutal on the lip. Well, our orchestra had this idea to do the symphonies consecutively, and the last three concerts were the Fourth through Ninth Symphonies on consecutive nights, with dress rehearsals every morning. On top of it all, we were recording the Fifth and the Eighth, with recording sessions after the concerts. Crazy, right? I knew how this was going to cut up my lip, and I wasn't looking forward to it.

I'm not an equipment changer. Before this I had been playing a Holton MC for about thirty years. Then two weeks before the festival Dr. Dave provided me with one of his Wedge Mouthpieces. The bottom of the rim looked so fat and round I immediately thought, "Hey this won't cut me up as bad as what I'm playing", but of course I had to check out how it played first. It took a couple of days to get used to it, but it felt good. I played the Wedge for the festival, and I played fine. I still got cut up, but not as much as I expected. Those big skips that Beethoven liked to write were not a problem. I'm happy. The Horn section is happy. My Music Director is happy. I'm not going back to my Holton MC. I play the Wedge from here out.

Now, can Dr. Dave make a wooden Wedge Mouthpiece for my Alphorn?"
