Wireless Set No. 52 Canadian - Project

[David Dunlop]

With the three boxes/cases finished for the 52-Set, the remaining details for them is to try and sort out how each was packed at the factory. Of these three items, the Tool Box comes closest to being self evident to where most of the tools were fitted. What is not clear is if each individual hand tool was wrapped in tissue when pack to reduce them sliding and rattling around during shipping.

For the two remaining cases, packing becomes more of a mystery. Since the Cases, Operating, Remote Receivers was the last of these items I finished, it has been on my mind the most. The easy bit, and most obvious is that the Supply Unit for the Remote Receiver must go in the central compartment. When located there and one picks up the case by its handle, the shear mass of the Supply Unit tilts the case to the rear and the Supply Unit ends up sliding to the back of the compartment, so it makes sense to snug it up, centred against the back wall, when you place it in the case. Once the Supply Unit is in the case, it becomes evident quickly that the cables to operate the supply are not all going to fit into the left hand compartment which already holds two sets of headphones and assorted aerial gear. That got me wondering about why the two internal partitions for this case stick up into the lid of the case and why both are notched back at both ends. Then I remembered a comment on Page 115 of the Working Instructions Manual which said:

“When space must be conserved, the Supply Unit may be used in the Case, Operating.”

Things started to make more sense after that. All the controls required to configure the Remote Supply Unit for AC or DC operation, are contained under its metal cover. When the cover is in place, this just leaves the terminals for the battery cable, the ON/OFF Switch and the socket for the power cable to the Remote Receiver exposed along the front edge of the Supply Unit.

The Connectors, Single, No. C3, used to jumper the two 6 Volt Wireless Batteries up to the required 12 Volts just slide nicely between the front wall of the case and the base of the Supply Unit. The Connectors, Twin, No. C1, which are the battery cables feeding into the Supply Unit remain connected to the front left corner of the Supply Unit and wrap around the notches in the left partition with the Meuller Clips coming to rest in the space in the central front of the Supply Unit. The Power Cable to the Remote Receiver says plugged in at the front right corner of the Supply Unit and wraps around the notches in the right partition with the connector plug also resting in the central front of the Supply Unit.

The photos in this Post and the following one will illustrate how all this comes together.
