Restoration of a Lachenal Edeophone
The condition of this instrument was, as most edeophones, rather bad. The
instrument has been
completely restored. Restoration included:
- repair and refinishing of the ends. Besides the 'holes'
caused by the thumbnail, several parts needed new
amboyna veneer. The finish
is French Polish.
- replacement of the Lachenal action. The action is
the weakest part of a Lachenal concertina. The best
way to 'solve' this problem is to replace it.
- replacement of bushings and springs etc.. a
standard restoration consist of :
Action: new springs, key hole bushing, key-lever bushing, key end circles,
pads/sampers, cleaning and
polishing of the keys, regulation of the action.
Key travel 3.2 mm, key pressure +-55 grams.
- reeds: new valves, voicing and tuning.
The instrument is tuned to A=440Hz. We skive our valves
to make sure to get the maximum air flow without the 'gurgle' of the valve.
- replacement bellows. Instead of
patching and re-staining worn bellows, I choose to replace them with
leather 7 fold bellows.
Note the 'hole' next to the thumbstrap, caused by the thumbnail. The amboyna
veneer has been
completely 'scraped' out.
The same instrument, finished. The 'hole' in the previous photo has been
replaced with a new piece
This is the standard Lachenal 'hook' action. The lever is kept in place by the
spring pressure. The action is
just as 'fast' as a riveted one, but it is very
noisy. It also needs more spring pressure to keep the pivot point
This extra pressure makes the instrument play heavier than a riveted one
This is the same instrument with a replacement riveted action.
The brass post, through which the lever
moves, eliminates all side movement of
the button. As a result the action is very quiet and even. The spring
can be reduced because the friction is reduced to a minimum.
condition of the bellows are beyond repair. Instead of 'patching' them, I
replaced them with new 7
fold all leather bellows.
