Since it seems to be in vogue that the casings of the speakers have rounded sides, we tried to give a comprehensive guide how to build such a casing. With this any aspiring craftsman should be able to impress not only the beloved but any visitor as well. So, without further ado, another written isntruction with pictures to illustrate.
As usual the construction starts with a pile of boards. In this case the side which has been split into 3 smaller boards which got an angle of 13°, so that wenn assembled this would give a curved surface. Lay out the boards flush next to each other with the front facing upwards.
In order to prevent unwanted movement of the boards we applied a strip of adhesive tape and then turned them around, so the rear faces upawards. Apply glue to the gaps between the boards.
The parts of the side get forced together by a clamp until the glue comes out of the gaps. Try to massage the superflous glue back into the gap, but the rest gets spread onto the adjacent areas with the finger.
After one hour of curing the sides could rejoin the boards necessary to build the kit. First the front was glued onto the base board.
Slightly unfocused but still recognisable how the angular sides have been glued behind the front and the back leaned onto it. And since the clamp was idly lying around we used it to keep the back in place while the glue cured as well. in the end, the lid was glued in place too.
The proturing edes of base and lid get removed flushly by the milling machine. Afterwards some measure of brute force is needed. With a belt sander and rachter rough sanding paper the edged form of the sides get sanded down until they are smooth and round. Take notice not to apply much force onto the belt sander and pull it with equal speed over the surface of the sides. It surely will pay off in the later steps of the project to train a little with the machienes.Back to: Design - Sloping edge Forward to: Design - Shadow joint
