BEFORE DESCRIPTION AFTER

Small Rack - Because this compartment was previously used as a mechanics and welding shop while the ship was at Ontario Place, both the short and tall racks had to be completely disassembled, degreased, primed and painted. The deck tiles which are badly damaged, will be dealt with at some later date.

120 VAC Distribution panel for UPX-1, UPX-5 and UPA-24 IFF equipment.

A 440 VAC supply outlet above the bench. The safety cap cannot be removed unless the switch is rotated to the OFF position as seen in both the before and after photos.

The 220 VDC distribution panel. The tally plate markings had to be rejuvenated.

EMR starboard side - On the tall rack there was a mixture of unpainted metal, primed metal (zinc chromate) and some overlapping shades of gray. A piece of test gear has now occupies the rack in the after photo. It is highly unlikely that the original IFF gear that was fitted in these racks will ever be found.

There were three coax cables for the IFF equipment. The reason for the serious deterioration on the lowest cable was only determined after the compartment was restored. Somehow water is seeping into one of the cables and is dripping into the
compartment. The root cause of the problem is still to be determined.

Much of the deck is laden with steel subs left over from the days when this used to be the 293 compartment. All these stubs made it very difficult to scrape the corrosion from the deck. At least 5 pounds of rust were scraped from the deck.

For reasons unknown to us, the 50 watt Admiralty Pattern public address amplifier was moved from the port passageway and installed on a small hand built table in the EMR. Added to that, was an outboard vacuum tube amplifier stage on the forward bulkhead. All this remains a mystery at this time.

Aft view. The grate in the bulkhead was an exhaust port of the 293 radar which used to occupy this compartment. In the after photo, some of the display equipment has already been put in place.

In the after photo, this is how it might have looked when the compartment was active.

Forward bullhead. Some of the PA wiring was found connected mid air. It then was routed into a connection box.

Below the workbench is the area where the electronics technicians stored their toolboxes. New pallets were constructed and fitted with angle brackets to keep the toolbox in place as was done in practice. New tool boxes, of the exact same dimensions as used by the RCN in the 50's and 60's, were purchased. Since fire engine red was not one of the "Pusser" colours, the toolboxes were repainted in other colours which might be found on navy issue toolboxes. The different colours are intended to signify different issue periods since a supply of the same colour could not always be guaranteed in naval stores. I still need to determine how the technicians identified their toolbox.

The extent of the soiled green workbench covering is very much in evidence in the before photo. To ensure that the material was not damaged in the process during cleaning, only the worst of the stains were cleaned.

N/A It's amazing how much grime can accumulate in 40 years. The after/before photo of one of the ventilation louvres illustrates this.

N/A Sitting on the shelf is the AN/UPM-6B radar/IFF test set. This was not part of HAIDA's fit but it certainly helps to fill some of the vacant space on the rack. It's rather doubtful whether it will be possible to ever locate the ship's missing IFF equipment.

N/A Since the book case on the aft bulkhead was missing, a replica was constructed. The Model OS-8 oscilloscope near the lower right originally saw service aboard the USS Ranger aircraft carrier.

N/A A large angle bracket which used to support one of the 293 radar components was never removed by the navy. Since we have no idea of how this space was utilized, two wooden pallets were constructed to facilitate storage. It is not known if HAIDA used the TS/147D test set specifically, but it's vintage navy and it sure helps to occupy an otherwise empty space.

N/A The automatic emergency lantern and its junction box. Normally the box cover would be painted but the restorer, Jerry Proc, has a soft spot for bright brass, hence he left his signature behind :-)
