good graphs, for some reason having the widest part of the reed at the top of the graph throws me a little but the information fits with my experience, except;
[*]All reeds are thinned, compared to the starting stock. It is perhaps surprising that a thinner stock isn't used as the starting point for treble reeds to save the need for profiling. Perhaps one of our makers could explain why?[/*]
To digress a little, if I was describing this information I would not call it "concertina reed information", I would call it information about the reeds in this particular concertina. If you use the words "reeds in Lachenal concertinas" you are talking about potentially three generations of reed makers; in that time they can discover and lose the same wisdom a few times over. Consequently the reed stock in Lachenal concertinas could vary wildly over time; maybe for just this concertina, or perhaps just that week, or that month etc, they used only 20thou and 35thou.
It is my experience over a number of measures that some instruments will have 3 or even 4 thicknesses, others will only have a couple. If you are happy to weight a number of the bass reeds then the concertina can be easily made with say, 20thou and 15thou.
It is common to find a concertina with high reeds made from approx. 10thou stock.
If you had access to a range of thicknesses why might Lachenal only use two?
The buyer forgot to order other thicknesses and there was a gap before more was obtained?
That particular reedmaker had a thing about using only a couple of thicknesses?
The dieset used to punch the thinnest stock was blunt and the toolmaker was in Wales because his father had died and there was no-one to sharpen it? (You cannot easily use one designed for thicker stock, the clearance between male and female relates to the thickness of the stock).
The dieset had broken and there were not enough orders to be sure there was enough money to have a new one made?
The reed maker had picked up his kitset of reeds, frames, clamps, screws and failed to see the stores wallah had picked some of the reed stock from the wrong bin?
Fred on the bench next door dared him to do it?
Fred, (that same bastard) bet him he couldn't do it and not have the foreman notice..?
