Reverse Schaller M4S tuners

[prowla]

I've got a set of 4 in a line (4R) Schaller M4S tuners, but I'd like to swap them to 2L + 2R.

Is this something which can be done (easily)?

Usually undoing the big screw and removing the gear allows the wormgear/keyshaft to be removed and reversed.

Not sure if that's possible with these - Schaller's website is hopeless. Maybe email them.

 

As a manufacturer it saves money and tooling to make them reversable, but it's not clear with this model.

Grrr - I dismantled it and the main headshell is directional; the keywind shaft will only go in from one end.

The part of the shaft leading out to the keywind has a sleeve around it and it has a tiny metal bar (a bit like if you snap the lead on a propelling pencil) which locates into a notch on the headshell.

So nope, they're not reversible.
