In Karen Loomis’s PhD thesis (volume 3, p.379-380) she prints two photographs of a shim from tuning pin hole no.23 on the Queen Mary harp. One shows the shim extracted; it is made from a split section of a feather quill.
On my replica, pins 29 and 30 have needed shimming for some years now. I had originally tried paper, and subsequently sheet brass, but I was inspired by this discovery, to pull the pins and try quill shims.
When I commissioned the harp from Davy Patton in 2006-7, the thing we were most lacking was info about the inside – the shapes of the joints, and the profile and thickness of the soundbox. Basically, we had to make a lot of educated guesses.
Since then, we have the CT-scans and other technical studies of the Queen Mary harp that Karen has been working on, and many of our guesses have turned out to be pleasingly correct, such as our choice of timber – willow for the soundbox, and a bent limb for the pillar – but we were quite wrong in our decisions on how to shape the soundbox interior.
Luckily, we had erred very much on the side of leaving the wood too thick, so last week I took the harp to Natalie Surina, of Ériú Harps in Oughterard, Connemara, for her to cut a lot of wood from inside the soundbox.
I have acquired an interesting old tuning pin. This is an early Irish harp tuning pin, probably dating from the sixteenth to the eighteenth century. I bought it from an Irish antiquities and coin dealer, who told me it was found in Co. Monaghan.
I’m very interested to consider this in the context of the surviving old harps, and to think about how most of us nowadays use modern pins, and how the differences have implications for the use and tuning of the harp.
When I was commissioning my replica of the Queen Mary harp in 2006, I paid attention to the 30th tuning pin, which is obviously a later addition, shorter, made of iron, split end, different drive, and off the main row. This pin is now missing but I made a copy of it based on descriptions and old photos. I made the 29 brass pins with their scores on their shafts copying the museum photo of the 21 pins now in the harp, and for the 8 missing pins I made the same design of brass pins without scores.
If I had been more on the ball back then I would have noticed that those same old photos and descriptions I used for the 30th pins, also show the missing 8 from the main row, and those missing 8 are plain iron not decorated brass, and 5 of them have split ends.
So today’s project was to make 8 handmade iron pins, and install them in the harp. The contrast of the iron and brass pins is subtle but interesting in appearance, reminding me of my initial reaction to the handmade decorated pins: “like medieval clockwork”.
I broke the lowest gold B string taking it off but there was enough spare to rewind the toggle and reuse it. The string had thinned where it went over the pin – presumably a gradual process over seven years since I fitted it in 2007.
The past week or two have continued the making things theme. I have done a series of tuning keys as test-runs; I have made a page advertising them which I will send out for my 1st May Emporium Update.
I also have made the set of pins for my HHSI Student Downhill harp, and today while it was here with my student who has it, I fitted the pins – pulling each of the old steel pins out in turn and then replacing it with a new brass pin. I had to shim all of the brass pins because for some reason they are marginally smaller than the steel pins, and I used thin brass sheet to make the shims. Plenty of the antique Gaelic harps have brass shims in their pin holes and I find it works well.
We instantly noticed how much better the harp worked to tune, with the new pins – the key fits much more snugly on the new pins with their tapering drives, giving a much more positive touch to the tuning. And the new pins look rather good with their decorated drives. I am very pleased with the result.
I have always thought that handmade pins with tapering drives work so much better than machine made steel pins with parallel drives, but inertia has meant I have not bothered doing anything about it until now. Hardly anyone has handmade pins on their harps, even top players with quality decorated instruments. I can only think of 3 or 4 off the top of my head.
I am going to make a few more pins and then I think I will make a page advertising them for sale for the 1st June update! I think that this would make a fantastic upgrade to anyone’s harp, to replace the pins!
