Bridle Strapped

It's been a super exciting few days, and this week is shaping up to be a lot of fun.

We started out tuning at a church in Kicukiro, near Nyanza Genocide Memorial, on Friday. It's a Korean-run church called Glory Bible Mission in Africa, with a US-made Kimball piano.

We'll go back in a couple of weeks as it hasn't been serviced in a very long time and needs a second pass. 

Rain stopped play at one point. We had to take an hour's break as the weather broke. We haven't had rain in about three months and a massive thunderstorm rolled in. The sound of the downpour against the tin roof made it impossible to hear the strings, but we were all grateful for the cool breeze.

The pastor's wife teaches piano and we headed over to one of her student's houses afterwards to look at a 1969 Japanese Kawai. The idea was to check it over and schedule a tuning, but on closer inspection, a couple of the bridle straps had gone and one of the hammers was entirely broken - so we kidnapped the action.


It's not easy untangling a Kawai action. Instead of solid wooden pedal polls, it's linked together with thick rubber tubing. Took a little bit of figuring out.

You can see the removed action at the top of this post. Désiré came to cart it off to the workshop this morning. He's working on repairing the hammer whilst Marion is dashing about town trying to find cotton braiding. We've ordered some standard bridle straps online but, as ever, we're keen to see what we can source locally. Bridle straps aren't exactly complicated - just braided cotton with a leather tab - but braided cotton is not something you can find in Kigali. We'll keep searching, but Plan B is in the post, thanks to eBay.

We're excited because this is our first proper repair job, and it'll be a challenge for Désiré to see how he gets on with fixing the hammer.

We're off to Chillington tomorrow to take a look at our string frame, which has taken a little longer than anticipated, but should be ready for collection on Friday. 

We then need to pop the original frame back into Lirika so that we can take the string measurements with Hellerbass's swanky tape measure. Then we can order our strings and a set of tuning pins. At this point, it's worth mentioning how incredibly patient Hellerbass have been with us, fielding all sorts of newbie questions. If you ever need to buy piano strings - one or many - look them up.

We're also shopping for tuning pin bushings, which we're likely to purchase from Howard Piano Industries as Steve Howard is someone else who has been extremely patient with our questions. We need two full sets, as Lirika's were pulled out when she was used to create the casting mould. It might be something we can make ourselves one day, but they're so small, fiddly and cheap, it's best just to order them for now.

But all these purchases really feel like progress and we're excited to start building our prototype very soon.

Flip the Flop

We're insanely excited.

These are the world's first piano hammers made from recycled flipflops, thanks to our friends at Ocean Sole, Kenya. 

We have no idea whether they will work, whether they will be durable enough or produce the right sound, and it will be a couple of months before we can test them properly, but it's a fun experiment. We're looking for ways to reduce the materials we need to import from outside the East Africa region.

Pinning it Down

Chillington have been hard at work forging a string frame for us. This is their second attempt. Still some problems with the pins, but this should get fixed in the finish. We hope to be able to collect it next week.

Strung Out

We received this in the post the other day. It's HellerBass's special tape measure for determining the length of new bass strings. It's got a little loop on it to attach to the pins.

The process seems rather complicated, and the forms are in German, so we're relying on friends to help us work out what goes where. Unfortunately, Google Translate reckons stimmwirbelbestellung means 'voting invertebrate order.'

Still, we have time.

We've been quiet whilst Chillington continues to work on the string frame. They made one casting but need to modify the tuning pin holes and recast. They're used to making hulking great agricultural machines, so the fine detail on a frame takes some adjustment.

Both the new and old frames need to be encased before we can take the measurements, because it's based on length between pins and bridge pins. The pins are on the frame, but the bridges (with their pins) are in the case. This means putting the original frame back in Lirika, then building a case for the new one to exactly the same specification.

Once we've got the measurements, we'll put in our order for strings and tuning pins, then sit back and wait another few weeks for everything to arrive. 

Building the first piano will take time as everything is new, but once we've got the process down we should just be able to order more frames and strings very quickly.

Meanwhile, take a look at what someone else has made. It's extremely cool - a fluid piano.

Good to Go

The Piano Girl by Kim Wilkowich


The Indiegogo funds arrived in our account. 

Thank you so much to everyone who's donated.

Chillington are already working on the string frame. The hammers have arrived in Nairobi, awaiting collection by Ocean Sole. Things are starting to look more hopeful.

Well, um... that was interesting.

We sent three piano hammers to Nairobi on 6 June. Just checked the post box today and they've been returned to us without explanation. They didn't make it as far as Marula Studios in Karen. We're not entirely sure what happened, but we're going to try DHL tomorrow.

Thankfully they're all in one piece.

Still, on the upside, we paid Chillington today and they're going to try casting our second string frame next week (the first one didn't turn out so well). We're really hoping high on this one. If Chillington can't do it, we might not be able to do it at all in Rwanda. 

They're going to be working hard in the heat. We're in the Long Dry Season at the moment. Which means a typical week looks like this:

 As opposed to the Long Wet Season, which looks more like this:

We're struggling a little as we still haven't received a penny of our Indiegogo funding. It's supposed to arrive within 15 working days after the campaign ends, which would have been Monday. But apparently there can be an extra five-days' delay for bank transfer. Still, it's got us rather nervous. Wouldn't recommend going down the Indiegogo route in the future, not if you're trying to get a project done before retirement.

Still, we're doing something - waiting on a frame - and therefore there is reason to feel excited. 

They're starting early next week. We're not sure exactly how long it'll take, but possibly in the region of two to three weeks. Chillington are confident for the most part, there's just a question over the accuracy of the tuning pin holes, which they reckon might be out by up to a millimetre. If that's the worst that happens, we should do fine.

So, if everyone could just hold their breaths for a couple of weeks...

That's it. 

Nobody breathe.

It's a sunny 27c in Kigali at the moment.

We've just got back from meeting the team at Chillington. This is where we're going to attempt to forge the second string frame. These guys are more used to producing industrial equipment, and the fine detail is giving them the same headache it gave Alex (the hitch pins and tuning pin holes), but we're going to give it a go. They seem excited about the project.

Unfortunately, our main problem at the moment is that Indiegogo still haven't released the funds. Considering they take a large chunk of the money we raise, a sense of urgency would be nice in return. Apparently, it takes up to fifteen working says. Our campaign ended on 12th June. That means we should receive it by next Monday. 

On the up-side, initial calculations suggest that building the prototype might not cost quite as much as originally thought. Especially if we go into production, as both the strings and the frames reduce in cost the more you order.

We're a very long way from production yet. We're still a long way from a prototype. But it's something to feel hopeful about.

Especially with the hammers stuck in the post to Nairobi, and needing to put Lirika's frame back in its case to take measurements before we can order strings... 

Pianos. Bloody complicated instruments.
