  1. post-536-0-97192200-1501061156_thumb.jpgHere are some I made myself. Maybe not the correct or best way but they are holding up fine thus far. I used 100g/sm good quality printing paper and then laser printed the design on.I gave them a coat of lacquer and fixed them on to the bellows with flour paste.It is important that they are either printed traditionally or laser printed.regards David.

     

  2. Another way would be to use the dowel and then cast the tops to whatever thickness straight on top in casein glue( Cascamite or whatever they currently call it) or epoxy .You could use white bath repair epoxy or natural and just colour to your choice.Then use your lathe to shape/tidy and finish. yes Titebond is a pva but it is nice quality, fast drying and as long as it has not been frosted dries opaque tan colour not dissimilar to hide glue.David.

  3. How about making them from dowel as a lot of them seem to have originally been. Like one of the old styles Ive seen you could "top" them with caps made form plastic.Perhaps circles cut from ping pong balls.The larger surface area should then allow a reasonable bond between the plastic and wood. I think the wood dowel to wood lever glued with something like Titebond will probably be more durable than animal glue.David.

  4. This was my first attempt at a Jeffries style case ,plenty of room for improvement.I like that type of case and they seem to seem to last better than most designs and protect the contents pretty well.As Chris mentions one problem with them is they do shrink so with that in mind I used a extra thick lining so it could be replaced with the normal thin velvet at a later date should this be a problem.Many years ago I made a similar shape case and behind the lining I put two layers of corrugated cardboard .That seems to have stood the test of time well as that concertina has been in and out of its case almost daily since 1980.Jeffries cases store on their sides well .I usually store mine with the handle facing one direction then after a few months I face it in the other direction.I guess its like turning a fine wine.

  5. The 7.25 inches diameter is a bit unclear to me. Is that across the flats, or across the corners?

     

    If it's across flats then it's a bigger than standard concertina. How that would affect it's value I have no idea.

    Yes that will be across the corners.That will make it 6 1/4" across the flats which is normal and will not affect the value the most important thing is whether anyone has mucked about with the reeds.David.

  6.  

    Looks like a rare concertina. Is that a Linota?

    Anybody know how you can tell?

     

    I have no intention of buying this instrument, but as I'm now living only a few miles

    away, I will probably stagger along on the viewing day (19 Sept) - just to have a look,

    and to see if it's playable.

     

    How do I tell if it is a Linota? What should I look for?

     

    Thank you.

    Those look like the original hand rests so they may have Linota stamped on them.if the reeds are in good shape it could be a really good concertina.David.

    My concertina case is wrapped in that sort of stuff. I have seen a lot of instrument cases with the same thing on them. Might be on a fabric type substrate though. Many years ago Rich morse was looking for something for bellows and found a number of coated fabric things, but they were either difficult to glue or had poor wear qualities. Eventually they just went to leather, but they do Wheatstone style bellows where papers are cosmetic, not used to cover the edges of the bottom hinge, gussets and top run, like on a Jeffries style bellows.

    But why go with faux leather when you could use the real thing if you are not looking for a printed pattern?

    good question.

     

    My reasoning was that for the cosmetic bellows paper (as you say not part of any of the hinges) a water-fast leather effect paper would be a cheaper and quicker alternative for bellows decorating as you would not have to bother with skiving the edges of lots of leather patches (unless you brought it very thin). I have a frank edgley concertina which has this stuff on it where it seems a pretty appropriate solution. I could always ask him what he used I guess

     

    A few years ago Andrew Norman made me a new set of bellows for a linota which has this type of textured leather paper so I guess he must know a supplier. I found him always to be very helpful so it would be worth approaching him to see if he might give you a lead.David.

  8. My guess would be if we could see the back view the other end of that centre joint/dovetail it would be a different size so when the bellows are fully compressed they can be slid apart .I think the idea of making a ten fold bellows out of two fives makes sense but I don't think that type of joint would be used.David.

  9. Patrick,That broken end is solid wood most boxes concertina or otherwise will be veneer.It also appears to be Brazilian rosewood so a lot more difficult to match successfully it will play fine with the end as is so I shouldn't be in a hurry to repair with anything inappropriate,all the best David.

  10. Hello Patrick,The grooves are for lining the pads up when building the concertina or replacing the pads.Without it is very difficult to place the pads evenly over the holes.If you have not worked in rosewood before there are a couple of things to be aware of it is hard and oily so glueing and polishing is more of an issue than something like mahoany.It smells beautiful when worked(a bit like roses) but is bad for your lungs so mask and ventilation are agood idea.If you use old wood maybe salvaged from furniture sand the surface before starting as the wood tends to go a lot darker, same with the existing concertina end,expect that to darken when you prepare for refinishing.It is best to try and get replacement wood as near to matching the original as possible as stain doesn't really work that well on rosewood.

    As others have said here it is a rare instrument and could be easily devalued not just from a finacial point of view .Good luck whatever you decide to do,David.
