S3 prototype in progress ...

Construction began today on the S3 point source horn prototype. The aim is to test the design prior to progressing further. 

Parts were CNC machined, but without any angled edges - these were done manually.

CNC parts:

Mounting plate turned on the lathe:

Edges needed to be angled on the buzzer, and sometimes needed some tweaking with the plane. This won't be required in the kit, but this kind of thing can be required when not relying on CNC for all machining.

This prototype is pretty "quick 'n dirty" but the final versionw will of course be very well sorted.
