  1. If you decide to work on it yourself, make sure you grab a copy of D. Elliott's book.
  2. Some detail can be seen in photo #8 showing a diagonal extrusion pattern typical of an FDM printer. As someone familiar with FDM printing I'd tell them to increase their wall count to smooth out the perimeter around the reed. I found this video of the instrument being played. Lucayala, is this the version with the printed reed plates?
  3. Great advice has already been given but I thought I'd share this video on making a different type of brass reed tongue. Some of the concepts might apply.
  4. Cillian King plays some highly impressive non-English/Irish stuff too. I don't understand why he doesn't have more views.
  5. It seems to me that if all the finger slide screws had been removed, that the slide itself could be removed. I wouldn't expect that metal piece to be glued down.
  6. If you only need the air button to close the bellows, then only the push reed needs to be removed. Edit: Oops, I see now that David has already made this point.
  7. In some instruments vibrational modes on the body are essential to radiate the sound. Examples would be a guitar, drum, violin, banjo. In these instruments materials will have a much greater impact on the sound since material density directly affects resonant frequency. I think the concertina is not in this class of instruments since the sound mainly comes from the reed itself. It will, however, be affected by the absorptive qualities of the material inside the concertina. Also, after watching this I was surprised at how similar a metal and wooden clarinet sound.
  8. Very nice linkage solution. I wonder what the lifespan of the Bowden cables is. I suppose they could be made replaceable if it is an issue. I'm also impressed with the finish on the handles. Is that stained wood-fill PLA? -George
  9. Seems they've had an admirable run but I'm sad to hear this. I'm hoping there's some way production of Morse models can continue. -George, proud owner of Morse #1481
  10. There's an interesting transposing concertina made by a Swiss company that plays chords on the right hand and bass notes on the left. Not sure if they'll ship overseas though.
  11. As a guitarist, I appreciate the concertina's ease on my joints and tendons. I imagine I'll appreciate this more with age.
  12. I sometimes use the Google metronome (type "metronome" in Google).
  13. I'm not a master builder but here's a thought. Maybe the resonance of your fretwork is tuned such that it absorbs energy from the F3 frequency. That is, the fretwork is acting like a tongue drum tuned in a way that interferes with the F3. You could probably test this by sticking hard modeling (plastalina) clay or mounting putty to the fretwork to alter or eliminate the resonances.
  14. Nice! It would be interesting to hear the tune played in different temperaments.
  15. Very nice design work! What type of filament are you using for buttons and the white lever paddles and will you be lubricating those?
  16. Very nice! Free reeds and plucked strings make a great pairing.
  17. Interesting. Seems like this would make it possible to pull the bellows into a straight cylinder, or a dodecagonal prism more precisely. Would this not cause stability problems?
  18. I really like their "bandoline", a bandoneon with an intuitive button arrangement, like a stringed instrument tuned in 5ths. -George
  19. I had this problem on my hybrid concertina. The cause was exactly as Dana described. I was able to fix it by gluing a thin sliver of photo negative to the valve like this. I should have tried Dana's methods first. Good luck! -George
  20. That's such a nice looking instrument. I think I understand the triplet technique now. Nice playing! -George
  21. Thanks, folks. That's really nice to hear from people whose playing I admire. About 14 months plus one pandemic so it has seemed like forever (almost two years total). I'm a long time guitarist though. -George
  22. Thanks guys! Interesting. I wonder why makers (except Stagi) didn't go wider when they started building them. Maybe tooling and materials reasons? Possibly. I haven't attempted the triplet technique, but I do have to hit the buttons more precisely or I will hit a neighboring button. Also, I have to hit the button from a higher angle, as lower angles can also cause neighboring buttons to be depressed. I have thought about giving the buttons a raised dome profile to help with this while still allowing easy two-note presses. -George
  23. Hello everyone. Several months ago I had recalled some musings on the forum about wider buttons on the Hayden duet, maybe from Brian himself. Having recently bought a 3d printer I realized I could print my own button caps to give wider buttons a try. Also, I thought that it would be nice to use my thumbs to better position my hands as I played. I find these enhancements very nice and will be keeping them. See the attached pictures to get a better idea of what I did. I don't like the term but I might call the wider buttons a game changer. They let me quickly play a P4 or P5 dyad with a finger tip. This was possible before but required more effort and finger bending, especially for thin fingers like mine. I posted a video in the "video and music" section of me playing with this setup. An important note in case you'd like to try this yourself: Make sure that everything you add is easily removable. The button caps should not be too snug or you will not be able to pull them off, leaving you with an unserviceable concertina! I made mine on the loose side and where needed added a bit of removeable mounting putty. The pictures show two button styles. I used the simple flat buttons for most keys. For the lowest row on each side I ended up using the contoured buttons to keep my fingers from slipping off due to the angle of my fingers and low friction against my nails. The button diameters are about 9.7mm. Cheers, -George
  24. Hello everyone. It took several months of practice and a couple of ergonomic enhancements to the instrument, but here's a performance of Maple Leaf Rag for the 52-button Hayden duet. I'll detail the enhancements I made in a separate post since I think they add a lot of capability to the Hayden. Cheers, -George
