Here is my second article about woodwind instrument making, it's about reamers, straight and conical.
Here again, the information is very difficult to find on the web, I hope this will help some beginner makers.
I explain two different technics, the one I used before I had a mill, and the preferred one, with a mill.
In English : Tapered Reamers
In French : Alésoirs coniques
In terms of tooling, there are interesting new stuff showed in this article :
- A spreadsheet for establishing a machining plan for roughing out a cone with steps :
Spreadsheet
- How to make any profile reamer, especially when copying an existing instrument, not really conical :
- My sort of tournebroche for holding the reamer while grinding the flute
- Very useful info : the fixture for holding the blank reamer for milling the flute.
Believe me, I have used several of them, this one is the most efficient and versatile for different sizes
- example of straight reamer, with three flutes:
- How to sharpen, raise the burr
- example of finished reamers :
