I've been doing some experimental re-stringing on my lever harp and wanted to use carbon fibre strings. My goodness, those strings are slippery & stretchy and handle completely differently from gut strings. So this morning I finally worked out a way of handling them better and here are the pictures.
[Never mind the time I spent trying to fix a knot into the carbon fibre string in the first place as it kept slipping apart. I'll post pictures of how I ended up doing the knots later. For now, this post & the pictures are all about the major issue (I think) with carbon fibre strings which is just how incredibly stretchy they are!]
When I wound the string onto the peg, there was so much stretch in the string, it took loads of turns to get it to pitch. Then when you left it to settle, it took more turns to get it back up to pitch. It took far longer to get to pitch than a regular gut (or nylon) string.
Which meant more coils round the peg.
The G string above was not too bad an example in that is was only 4 turns round, but it was still going flat and need another twist round to sharpen to pitch.
So I unwound the string making sure to keep the tension by hand as much as possible with the lower part of the string to create as little movement on the knot as possible. Then I pulled the string back up to take out the slack.
Then I re-engaged the string to the pin from this new point. Don't leave any slack in the string - trust me it will stretch. I had over 4 cm of extra string when I pulled it through; that is how much stretch and slack had accumulated over a period of 5 days from first putting the string on the harp.
After one full revolution to then push the string towards the harp, so that now when it wound on it would lock and wind over itself.
The important thing being to then trim the excess, so that eventually you would 'lose' the 'tail' under the coils as it winds on.
You might think this all seems blindingly obvious, but trust me, using carbon fibre strings feels SO different to gut & nylon. I think you need to double or triple the time you would normally spend stringing, tuning and settling in the string. HOWEVER... once it's settled and in tune, I think carbon fibre are brilliant strings.
***I am using these on my lever harp but certainly would not think about using these on my pedal harps***
I'll answer that in my next blog post.
