My house organ has a positive division measuring approximately 2m wide by 1m deep by 1.4m high.
It comprises a heavy outer case containing display pipes which are connected by conveyances to the wind chest, upon which the remaining pipes stand internally. The wind chest is not directly connected to the outer case but simply sits within it. The positive is positioned against a wall which makes direct access for tuning from the rear impossible. The action is direct electric to a slider chest. It has its own small blower installed within the case.
Does anyone know of a roller system which could take the considerable weight of this assembly and make possible movement at least 18" or so forwards so that tuning from the rear becomes possible. Raising the height a few inches would not matter at all.
