18 Jun 10 - 08:03 AM (#2930432) Subject: Toy melodeon - sealing the bellows From: Bloke from Poole Hi, I have a little toy melodeon, seven buttons, in C. It is playable, but the bellows are very leaky. I guess this is by design, to avoid damage - the seals on the edge don't meet/close in the corners. But I would like to improve the seal, it is hard work to play, even for fun. It has an air button I was thinking of trying a flexible glue like Copydex or similar. Wondering if anyone has any better ideas? Malcolm PS I shall be internet-less for a couple of weeks, from Saturday, not being rude if I don't reply to anyone! |

For a toy, not an expensive instrument (which wouldn't have the problem in the first place). Copydex wouldn't work so well, I wouldn't think. |

Tape of any type is useless - it is too thick and inflexible and stops the bellows closing and working properly. If anyone has any of those little piano accordions that they want to move on - please let me know. |

20 Jun 10 - 01:29 PM (#2931530) Subject: RE: Toy melodeon - sealing thebellows From: Bernard I'd advise against any self-adhesive tape... Sellotape and gaffer tape both dry out, fall off and leave a powdery residue behind, and PVC tape leaves a gungy goo behind. |

22 Sep 10 - 07:19 AM (#2991348) Subject: RE: Toy melodeon - sealing thebellows From: Bloke from Poole I have had some success with tent seam sealant, which I just happened to have next to the box - and made the connection. It has make a big difference, although it was something of a fart to do. Had to fix it with the bellows extended for 24hrs for the glue to dry. Next plan is to see if I can blank off one set of reeds because I don't like the tuning, see if it sounds better - and the air goes further - with one set. |

The bellows need to be fixed open and the glue allowed to dry for 24 hours. I always used a touch of talcum powder to finish it off, but only being cautious. Most of my bellows repairs are done from the inside rather than the outside. Al |

Or if you are a cheap B .... like me.... Become hip to "Monkey Grip" (It keeps mine leather-sacked bellow on the organ below pumping fine.) There IS a reason for the "blow-out valve" you are describing....it prevents permanent bending of the reeds or a major blow-out (think baby's diaper.)

23 Sep 10 - 05:37 AM (#2992076) Subject: RE: Toy melodeon - sealing thebellows From: GUEST,Pete I like to use masking tape to reinforce the creases on Ordnance Survey maps.It folds better than Sellotape, and doesn't dry out and fall off. Don't know how it would stand up to constant flexing, but it would be easy to replace. |
