More progress on my second point source horn prototype.
Assembling the second flare section. First they are screwed together to check they are correct. Then glued.
It sits on top to check alignment.
Drilling port holes.
Previously this was done before assembly, but this time I decided to try it the other way. You can see above a test sample. It was drilled from the inside out to actually find the exact location. Obviously drilling on the assembled horn is from the outside in.

Now it can be dimensioned:
Filling the joins:
You can see there is quite a bit of patching. Ports have now been drilled:
Assembled horn with mounting baffles:
The mounting for my Miniwaves is also shown on the right.
Horn flare transition has been smoothed:
Baffles added to allow six 5" mids to be added. Ports this time will be 9mm deep, and flaring is required to achieve this.
