  1. Ok, I finally fixed the old 55 button bandoneon and it is playing again.

    I replaced a few gussets and patched some leaks in the bellows. 

    I made 16 buttons (thanks to instructions from Harry Geuns in Belgium)

    I replaced one broken reed tongue (Harry sent me a new one.)

    Then I replaced the leather pads on the left side (but it is still leaking some air on the left).

    What an interesting instrument: It is basically an Anglo with rows of chords in G, A and E, and then a lot of other accidentals.

    It might be easier to simply machine them from Delrin.  I had to replace the buttons on my concertina (I bought it in a condition where many of the metal buttons were worn down significantly.)  What I did was buy Delrin rods from McMaster-Carr, and mill them to shape with a Dremel tool.


    To make the bottom peg of the button, I discovered a neat Dremel trick.  I set a Dremel tool in that dinky Dremel drill press that they sell, with a fat cylindrical grinding bit close to the drill press platform (a little less than one rod diameter away).  Then I'd take a few inches of Delrin rod, hold it firmly to the platform with both hands at the ends, and roll it firmly so that the middle of it rolls into/under the grinding bit.  By rolling it in, this mills the middle to a skinnier diameter, and I then cut it in the middle to produce two button blanks.


    It took surprisingly little time to make a full set of replacement buttons this way, machined with great uniformity despite my grad student budget and my cheapo tools.


    Can you please show a picture or video how you do it?


  3. So, I have been thinking what finish to put on the veneer when I am done. I have done a few wallnut gun stocks with a "London oil finish", using boiled linseed oil. It takes a long time to do- each very thin layer of oil must get dry before it is rubbed and a new layer applied. The old recipe went: once a day for a week, once a week for a month, once a month......

    What do you guys think?

    I recommend not using any glue that has water in it for veneering the end boards. If you do there's a high risk of them warping when the glue dries. Polyurethane glue, contact adhesive, or epoxy resin are some examples of glue that don't contain water.

    Unfortunately I could not find Polyurethane glue, contact adhesive, or epoxy resin in my small town, so my only option was to use PVA wood glue. I apply the glue and then clamp it for 24 hours to try and avoid warping. So far it went well.

    I also don't have brad point bit drills, so I made a chisel with a round side out of a 8mm steel bolt to cut the holes in the veneer and then finished the holes off with a dremel.

  5. Thank you Simon, I have found veneer. The company gives away free A4 size samples and they sent me enough to do ten concertinas.

    Now, I have never worked with veneer. Can anybody please give some instructions how to do it the correct way? How do I get the holes for the buttons and sound holes? Should I first mark the holes with a pencil and then punch it out, and then glue the sheet to the ends, and when it is dry, finish it off with a dremel? Will PVA glue be ok?

    Thank you for your help

  6. I just received a very old, pre Chinese, Hohner International (Bastari) D20/40/8. It plays very nice and the sound is very good.

    It has a red Mother of toilet seat finish, which is pealing off. Some places the pearloid cover is very buckled and I do not think it can be glued back. Can anybody please advise how I can repair it? Should I rather remove all the pearloid plastic and clean and sand the wood and then stain and varnish the wood?

    Any help will be appreciated.

    Thank you.

  7. My cat also likes music. When I start playing, he jumps on my lap and rubs himself against the concertina. When I play harmonica he rubs his nose against the back of the harmonica, as if he is helping to play.

    My sister has a cat that attacks her when she plays on the old peddle organ.

    I have wondered, do they really like the music, or does the sound irritate their ears?

  8. Since childhood I wanted to learn to play concertina. About a year ago, during the Covid lockdown, I decided its time to bite the bullet. But what do you buy? If you buy an expensive concertina and cannot manage to play it, then you wasted a lot of money. So, I decided to order a cheap Chinese 20 button Anglo from Banggood. Yes, it is hard to play- the bellows are very stiff, but in a few months I managed to play it and the more I played it, the easier it became. A few months ago I moved on, I found an almost new 40 button Hohner with metal buttons and -ends and leather bellows. What a pleasure to play! I will never be sorry that I started with the Chinese 20 button, and I still play it now and then.

    Just my 2c.
