No no, lumber for a boat so I can sail from Kungsbacka to Capetown bringing the real, paper, drawings and giving You very bad advice on how to build those horns.

Now THAT would be a story for the ages - not so much you facing the ocean for thousands of miles in your little boat, but you giving bad advice - it would probably be the first time!

How do we put those pieces of wood together then?

No pictures of my build yet as I presently am bying new tools due to the fact that I gave them all away when I last moved the workshop to new premises, didnīt tink I would need them any more, trust SA friends to change that.

But some simple guidelines on how to build this horn here, actually extremely simple to build.

First thing, real, water based, wood glue, and remember there is no such thing as too much glue, all inner joints must be air tight.

Use screws too where convinient, always predrill when using crews, newer use screws in plywood or other board material without pre drilling.

1.Glue top, front and the 2 side walls of first chamber, 152x1050 + first horn wall, 200x904 together, use as much screws You feel apropriate.

2.Glue Bottom and outher side walls together with the already finished parts, use screws where You want.

3.Glue second horn walls, 152x950, 2pcs, to front, bottom and outher side walls.

4.Glue and screw the first chamber rear wall, with the 2 85x150 cut outs at the top to the already assembled parts, this should also
have a hole of suitable size for inserting the speaker wire to the speaker chamber, insert wire now.

5.Glue third horn wall to the existing structure, horn finished.

Thank you so much, Ingvar! I truly appreciate your kindness, all the time and effort, and the knowledge you are sharing...

I just wonder what happened to all the other guys that were so involved and excited at the beginning of this thread?  :???:
