So, umm, this happened…

I am a gadfly. A flibbety-gibbet. A floosie. I have abandoned my old console in favour of a new model.

It wasn’t planned, but when it popped up on eBay, I knew it was too good an opportunity to pass up. This little beauty travelled all they way from Devonshire to Norfolk this week. It is extraordinarily heavy, and the movers did a sterling job (which, once again, involved taking the front door off).

Much as I love the old console, it was becoming increasingly apparent that it would not be easy to modify it to do the things I need it to do. The toe-pistons being the most obdurate sticking-point. You will observe that the new console has toe pistons in abundance (21, in fact). It also has drawstops. Yes, they are actual, genuine, functional Kimber Allen mini drawstops.

The old console has been sold, and will be collected sometime next week, but in the meantime I have started to do a little bit of stripping out. In actual fact, very little of the work that I have done so far will need to be re-done on the new console, apart from putting in the pedal reed switches again. Almost everything else that I have done has been confined to the manuals, which will be transferred into the new console.

I have started to put things on eBay, and hopefully I will recoup some of the cost (£637, including transport) by doing that. So far, the external speaker cabinet and two (!) Quad amps are up for sale. Mr Norwich Organs has been round, examined the console and pronounced it a good purchase, and has also put in claims on a few of the components. The manuals will hit eBay in a week or so, too.

The main thing I need to think about is how to put in the stops for the solo division. This will need to be a touchscreen. I have some ideas, but I need to think about it. That is for the future, though.

An update

So the last few weeks have not been particularly fun.  Betty took ill, and then died last week.  It was expected (she was a very old dog, with numerous serious ailments) but it still hit me hard.  Consequently I haven’t been in the mood for organ building, or writing about it.  Bailey has decided that now would be a good time to come into season (well planned, since she was due to be speyed on Thursday).  Everything feels a bit flat.

There has been a little progress in recent days.  I have continued to make minor adjustments to the magnets on the pedalboard, and am now reasonably happy with them.  I have also installed a micro-DIN plug in the connecting cable, to make it easier to remove the pedalboard.  I will have to do the same thing for the expression pedal connectors, when they are eventually installed, as these feed into the pedalboard MIDI module via a short connector cable.

I’ve also purchased twelve toe-pistons, ready for installation when the kneeboard is re-jigged (approximately some time soonish).  Currently amusing the parental units, so no further updates for a week or so.  The next task is to screw down the manuals and connect the thumb pistons.  I might then be able to produce some noise.

Irritation

I ordered a male/female pair of mini-DIN plugs, to make it easier to separate the pedalboard from the console.  These arrived today, and I’ll do some soldering tomorrow.  Watch this space.

Last week, I also bought a box of 3 1/2″ wood screws, to screw down the manuals.  Only, I can’t find it anywhere.  I feel that it may have inadvertently slipped through a rip in the space/time continuum, and is now sitting unloved on someone’s garage shelf in Guatemala.  I’m really quite cross.  There are only limited places where I could put a box of wood screws, and it isn’t in any of them.  Out of an abundance of caution I’ve also checked the fridge, and it’s not there either.

Grr.

Histrionics

Never mind busy, it’s just been far too hot to slave away over the pedalboard.  There has been some progress, however.  I have now completed the testing (and relocation where necessary) of the neodymium magnets.  As I’ve mentioned repeatedly, I’m not absolutely happy with all of them, but I need to actually use the pedalboard before I make any further adjustments.  Here is a progress photo.

You can see that the magnets are not linear.  This offends my sense of aesthetics, but I will just have to live with it.

I am currently looking for a 4-wire connector that I can insert into the long MIDI cable – as it is, both ends of it are rather inaccessible, and there is the risk of damage if the pedalboard is separated from the console.  Problem is, I can’t quite describe what it is I’m looking for, so I don’t know how to buy it from an internet shop.  “4-wire connector” is apparently not descriptive enough.  What I want is a… thing… that, you know, does… stuff.

Hysteria

Work has taken up much of my time this week, and there doesn’t look to be much improvement until the end of July at the earliest.  So the delay in starting work on the kneeboard, toe-pistons and expression pedals caused by various experts going on holiday is not actually going to inconvenience me.  This week I have continued work on the reed switches.  I have mounted all three banks of switches, and adjusted the magnet distance on the central bank.  Most were fine, but a couple needed raising by 2mm (four washers), and a couple more needed the magnet relocating  I’ll work on the remainder this week, if I get time.

I’ve no doubt that once I start using the pedals properly I will find a few which need additional fine tuning, but I’m happy with how things are going so far.

Hysteresis

Where does the time go?

Last week I was mostly preoccupied by aligning the reed switches to the magnets.  There is still more work to do on this.  The challenge is getting all the magnets the correct distance from their switch.  I am waiting for some nylon washers to arrive, which will allow me to raise individual magnets by 0.5mm at a time until I get the correct distance, but I suspect that one or two of the pedals will need a fraction shaving off the end to increase the distance when in the ‘off’ position.  Hysteresis is a harsh mistress.

Expecting the toe pistons to arrive next week, but there is quite a bit of cabinetry to be done on the kneeboard, to make them fit.  This will probably turn out to be the most complex part of the build.  Fortunately I have expert help.

Below the belt

Recently I have been focusing my activities on what happens below the keyboards.  You can see in the photo that I have now attached neodymium magnets to each of the pedals, and the reed switches are laid out on the bench in front.  The spacing is perfect, so all that remains for me to do is to work out the correct distance between the magnets and the reed switches, and secure the circuit boards accordingly.

The next step, once the pedalboard is properly assembled, is to secure the manuals to the console and make sure that everything is properly wired-up.  Then I might be able to actually play something.

In other news, I had a visit from organ royalty yesterday, to look at the instrument thusfar assembled and discuss the correct positioning of the swell shoes (increasing their number from two to three) and toe pistons.   Measurements were taken, chins were scratched and the merits of the RCO console specification were reflected upon.  There will be a return visit in the not-too-distant future, for some experimentation.  Then the knee board will be taken away for a gurt big ‘ole to be cut in it.  I am very fortunate to have the advice of such vastly experienced masters of the craft.

Both dogs are now in full moult, and there is a layer of hair over everything.  I have given up trying to keep the house clean, and have settled for keeping the hair down to under waist-deep.

A mini-update

Still ridiculously busy, but hope to have more free time later this month to work on the pedal reed switches.  I am also in discussions with Mr Norwich Organs about the swell pedals and concomitant adjustments to the kneeboard.  In the meantime, I have finished affixing the MIDI modules to the console:

Beautiful, is it not?  Pay not attention to the apparently wonky placement of the module on the right – it is perfectly straight; your eyes are crooked.

There is enough space on this board to fit several additional modules should they be required.  I think I may actually run out of space on the MRG2, and will need an additional one at some point.  However, that is a problem for future consideration.

In dog-related news, Mia’s space on the bed (but not her space in my heart) is now occupied by Bailey, another rescue – a younger bullmastiff/French mastiff cross.  She is boss-eyed and has no hips (at the moment; she’s dieting), but she is quite gorgeous, and very affectionate.  She has immediately adopted Betty as her foster-mother, and Betty has stoically accepted the same.  She gives me long-suffering looks whenever I glance her way, but I have secretly observed her wagging her tail and allowing Bailey to share her sofa.  She’s not as tough as she likes me to think.
