I am thinking of making a Carbon Fibre Harp.
I am having a problem with how to make the neck and column.
If you don't know, this is shaped like a curly number seven. It needs to be very strong as it has about 500 Kg of pull across it from the strings. I would like to make it in one piece. The sound box fits between the ends of the seven but this is relatively easy.
I was thinking of making it in a mould made of sheets of MDF laid flat with the cavity cut out of the middle sections.
I would make the piece by wrapping layers of Carbon Fibre around sections of expanded polystyrene so that it would end up with an internal box section support structure.
I would also include a bicycle inner tube so that when the top is bolted on to the mould I could inflate this and force the piece into the corners.
I was wondering if I could laminate using infusion resin and include a length of spiral tube between layers leading out of the mould so surplus resin would be forced out. I think the laminating resin would be too thick to do this.
Does anyone think this would work?
Brian.

Thank you for the comments.
I have done a lot of reading and thinking since I posted this.
I have changed the way I plan to make it. I will (When I get the time to make it!) take lots of photos and and tell you all how I get on.
Brian.
