Rim and bite diameters (times 2 as they are in radii). So, 31 thou from the crown of the rim the gRawlin 1 measures .6412", At 50 thou it measures .6174". Depth .417/10.59
gRawlin #2 same except depth is .437
gRawlin #3 same except depth is .457
Rim OD is 1.10", bore on the tops is 27.
The flugel/cornet has the same rim, a standard depth flugel cup .750" deep, and a #18 bore (.170")
See below for Alpha angle information. The gRawlin Rim is a Low Alpha angle that does not trap the chops. This allows lips to vibrate freely and makes the mouthpiece feel bigger. This is very important for an AirPlay free vibrating lip surface
This is the gRawlin #1 Top
This is the gRawlin Flugel / Cornet cup
Not shown is the tighter second cup for the cornet mouthpiece. I plan on posting a detail drawing soon. The rim, the contour, and the throat is the same for both Flugel and Cornet - only the second cup (entrance to the throat) is more defined and tighter for the cornet.
This is the gRawlin #1 Top and rim.
