I'm not so sure it is all that easy. It would require a more complex 2-piece mold. To accurately conform to different throat angles, the contour can change significantly.
Yes, the contour of the throat...not the rest of the waveguide. I view the two as separable.
The talk of all the possible combinations is the genesis for my comment.
Even for different throat angles, the mouth of the waveguide can remain virtually the same. The throat of the OS profile is where the changes occur. The first 2" of the waveguide comprises what? 15% of the machine time invested?
Considering a SEOS 15 as an example...not a SEOS 14.8 or SEOS 15.2. Saying "SEOS 15" is defining the gross dimensions of the mouth.
Once (if) a commitment is made to the first 2-part mold, any throat angle thereafter may be made for less $$$ than a new one piece mold.
Extending this further...the mouth of a SEOS 15 or 18 could be configured to receive 1", 1.4" and 2" throats.
For anyone who would like, I will send an excel worksheet to help understand this. Send your request to:
