I finally finished making my own double concertina case. I had been admiring Mark Davies' lovely case and he suggested off-hand that I should make one. I needed one but I was put off by the price and thought I could make one easily enough. There are basically two kinds of double case. One kind is suitable for carrying around to the pub with you (100-150) and the other is a more protective flight case, well-padded and very heavy, that can run well over 200. I made the first.
In case anybody is interested, I used 3/8 fairly rough plywood that I had lying around. I made a box, cut it to make a 2 lid, painted it with paint I had already bought, lined the inside and the lid with green felt-like material that I bought at a fabric shop for 7, and put on the hardware that I bought from www.fixdiy.com for about 15.
Altogether it cost me about 25. I have enough material left to line another case.
It isnt very elegant but it serves the purpose-- and I saved 75-100 over buying one already made. It took hours to make, however, and Im not factoring that into the cost of the case.
I may still cover the box with black vinyl from the fabric store. The gloss black paint is very garish.

As it turns out, I also built a multi-concertina case last month, and thought you'd like to see it too. Cocosflute mentioned two levels of cases, and that his target was the more economical version....and the results show he more than met his goal with a useful product. My needs were a bit different, but probably were closest to his upper end described level.
My case had to address several issues:
1) It had to provide much better protection than my existing cases that came with the instruments. I live an hour or more from the nearest session or dance, along roads that are often bumpy in my truck. I play out quite often, and am always taking the instruments in and out of the house and into the truck, etc. I was looking for rugged and padded...original cases are often just thin wood with a layer of velvet, and no padding. More importantly, it is hot and humid here for four months of the year. The instrument goes from a cool dry house to a hot humid walk to the carport, then a hot truck until it cools off via ac, then reverse of that when I get to my destination. I'm looking for thermal insulation in addition to padding.
2) It had to carry three instruments. Yes, I play them all....a CG and GD anglo, and an English system. Often, at English country dances, a few new tunes are spontaneously brought by dancers that we hadn't learned before. I can sight read on English up to tempo for the dancers (within the group I am in), but not nearly that fast on the anglo. Once I learn them in my head, in following days, they usually get transferred to one or the other anglo, unless they are more suited to remain on the EC. I asked a couple of case builders if they would consider a triple case...no takers. So I fired up the table saw and got to work.
I used 1/4 inch birch ply (like cocos, leftovers) and poplar struts. As you can see from the photo, all joints were both glued and screwed...this case is both reasonably light and very strong. It also, I think, will go as an airline carry on, but with present weight restrictions and fees I am not likely to test that.
The interior is lined with bare closed-cell polyurethan foam, bought from McMaster and Carr. It is firm enough to hold the instruments nicely in place with no rattling, and yet forgiving when bumped. Closed cell means no absorption of humidity, and it is very lightweight. The instruments are protected in all directions by an inch or so of this thermal insulation/padding...very protective. It is gentle to the touch, not abrasive...no rubbing issues to date. I was going to further line it with the traditional velour...and then realized that professional photographers put their equally expensive cameras in cases lined just with this same species of foam...so why mess with that extra step?
In a nod to fanciness, I put a cover of surplus leather on the inside of the top and bottom....not necessary, but dressy. I think the foam by itself would be fine.
The outside is lined with a plastic material used for speaker covers; it is very tough. I got mine from Stewart McDonald (thanks, Greg J., for the tip). The hardware came from Rockler, and is similar to that used by cocosflute.
The weight is less than the three original cases together, and yet this case is far and away more protective. I put the main handle on the opening side rather than the top; this leaves a nice flat surface when the box is closed to set instruments or beer on. A second handle went on one end...very handy when getting into buses, into cabs, etc. Some rubber bumpers on the bottom allow me to put this on furniture without fear of scratching (thanks, Harold H.!).
I think cocosflute's solution is
plenty acceptable (for Ireland, though not particularly for Texas) and very cost effective. I would not build one as I did if just to save money....all the parts (including the foam, glues, external covering and hardware) added up to a surprising figure, because when you buy for a small project you are often forced to buy more material than you need, or in expensive small amounts. And then there is the labor, though it was a satisfying small project to do. A single case that Greg Jowaises made for me is easily the equal of mine (although I would add more insulation for my climate), and really a bargain...but again that was not an option, as triples were not in the offing by any builder I asked. I am pretty happy with the result, and glad my concertinas are better protected when on the move. And no more juggling cases!
Cheers,
Dan
