Hi,

The neck of the Harp that I made is twisting. This is not surprising as the pull of the strings is 660Lbs or 300Kg. To put this into perspective, that is a 1300cc Suzuki Hayabusa and rider hung 15mm away from the side. The wooden harp that this is based on twists slightly worse than this.

Would putting your 250gsm unidirectional carbon fibre on the side that is under tension help with this? The side that is under compression has become a bit lumpy, a bit like fish scales.

Any other suggestions for improving this?

Did I read somewhere that there is a problem with infusing Unidirectional fibre?

Brian.

This is how the neck bends.



This is a reminder of what the harp looks like.
