More Progress On The Corner Midrange Horn

Here is one of the side flares in position.

With the first flare nearly fitted, I used it to mark the other three flares to save some time.  After further fitting of all four sides, I was able to mount them all to the corner.

It helps that the paneling is somewhat flexible.  By measuring the width of the core flare, it was possible to improve the fit and symmetry of the mating side flare edges.  Finally, I could insert the core flare into the space between the side flair pairs.  Here is a picture of the horn on its side:

Here are pictures of each side of the horn:

I used coarse sandpaper to remove the last of the edges that were still pushing too hard into the central core.  Here is a strip of sandpaper removing material from the edge of the side flare to improve the fit.  It helps that the paneling is flexible enough to distort enough so you can see where to remove more from the edge.



Here is a picture looking into the vertical shaft in the corner where the pair of throat horns will be located:

The next step will be to construct and fit the throat flares.
