Seek Duo-Art Expression Box Adjustment Screw
By Peter Warburton

Hi there,  I have struck a problem with a Duo-Art grand that I have
been working on.  When making some initial adjustments on the expression
box one of the adjustment screws broke.  (I had loosened the lock screw,
but I now realise that the mechanism was fouling with the crash valve
pallet that had somehow gotten out of its correct orientation).

Does anyone know whether or not new ones are available, or maybe someone
has a spare they would be willing to sell?  I guess if I get no response
I will have to see about getting one machined up, but I would rather
avoid this if possible as I imagine it could be costly.

The screw/bolt is the one that has a small washer that fits over its end
which is held on by what appears to be a small pin that passes through
the end of the screw/bolt.  Any help or suggestions would be much
appreciated.

Cheers,
Peter Warburton
