Your thoughts on this key mechanism?

[Plinky]

Hi Guys/gals my friend sent me this is as a possible option for an accordion key mechanism ,for the project boxes we are working on.



I know it's not on accordion but I quite like the idea of extension springs but I would also like the keys on separate axles?
not one long rod.
And it would be easy to add a pallet rods

No valves?and the slotted reed chambers?
Interesting ,I have never played or owned a melodica so its very new to me.

And it sounds great

I wonder if anybody any thoughts of the practicality ,of maybe they tried something similer.
many thanks

What an incredible amount of work (and tools needed to do it...)!

Hi De bra,it's certainly quite an elaborate job I think you 3d print?
I thought about simplifying the keys caps and luckily my mate's dad has a machine shop ,they make high end office furniture and have some very cool equipment.

He says he used the highest quality accordion reeds and I'm intrigued by the little slotted reed chambers and no valves ,and I certainly wasn't expecting to to sound anything like that good.

There are no valves, because melodicas and accordinas are single acting - they only play on the blow. You don't breathe in through melodicas as you do with harmonicas. You can buy dedicated melodica reeds from harmonikas.cz (may even be the source of his reeds, as harmonikas.cz sell single sets to individuals, something other companies often do not want to do).

Hi nou that's brilliant ,really made me chuckle it just hadn't occurred to me

I cannot 3D print this large with my printer.
Around 14:22 in the video the work on the reeds begins. The reed plates contain just a single reed tongue each, so there is no "opposing reed" for which a valve can be used. The range of the instrument is G3 up to E6, and that can be comfortably done with reeds that have no valves. If you were to go up to C7, like on a typical accordina, some reeds start having trouble starting, and then poking a small hole (with a needle) through the wax may be needed to provide a bit of "spilled air" which in an accordion just goes through the opening for the opposing reed in an accordion.

Hi De bra,many thanks

To be honest I was sent the video specifically for the keyboard design ,but I'm easily drawn into “following a thread”
Someone posted a great video of the Jacquard mechanism here ,and I then spent the next several hours researching and eventually ending up with Scottish traditional weaving methods and the meaning of various tartans.

Sounds very familiar
