How To: New Wire-5 project (Bergeron)

[Robert Bergeron]

Yes Bob, the word “party” comes to mind .We will call it a Jimmy party . …. I have corraled a number of injured former Sigs veterans and working these antique trucks / wireless sets will , i hope ,set them on the way to recovery . Small victories build self esteem and help transition to the civilian world . . Bruce , i found the proper terminolgy in the Emers . Connectors , Pigtail is the proper official Canadian designation .

I think you need "Aerial Feeder No.9" rather than "Leads, Aerial, C6" because the C6 is intended to connect the telescopic mast to the roof insulator when the mast is mounted on the vehicle roof. It's far too short to reach from the set to the underside of the aerial base. (They're very similar: a plated brass plug to mimic the base of the bottom 'F' aerial rod, and a length of insulated wire (British ones use P11 cable) to a ring terminal. The plug goes into the aerial base behind the variometer (I'm assuming this is the demountable station on Carrier No.3 or 23) and into the bottom of the aerial base.

The pigtail is intended to be an easily (and cheaply) replaceable link between the aerial connection plate and the aerial socket on the base, to allow for flexing of the rubber base and consequent metal fatigue of the connection - you can replace the pigtail rather than the aerial feeder (likewise if the base is damaged by impact with tree branches or gunfire).

You will need a rubber or cork gasket between the connection plate and the aerial roof mounting to keep rainwater out of the vehicle - the spacer (Aerial Base No.8 Mounting No.3) has been made from many things over the years: plywood with cork gaskets glued on, moulded rubber, and the post-WW2 pair of steel dishes seam-welded together (issued with a pair of rubber gaskets).

The sponge rubber sleeve is to protect the feeder from damage if it rubs against the metal parts of the vehicle. (I bought some circular cross-section rubber insulation and a set of cork-borers for making the central hole.)

Best regards,
Chris.

I found my scan of the installation guide for the WS19 into 'House Type Body', and this is the section on the aerial feeder:

(22) Connect the terminal end of the Aerial Feeder Assembly No.9 to the terminal on the Aerial Feeder Connector plate. Drop the flexible lead through the hole in the Aerial Feeder Housing, located at the forward end of the vehicle roof in the centre. Place the aerial feeder connector plate over the aerial feeder housing and place the Mounting No.3 over this. Take the Aerial Base No.8 and screw in the connector pigtail No.1, then place this base over the above assembly, tilting slightly so that the free end of the pigtail may be connected to the terminal on the connector plate.

(23) Secure the above assembly to the Aerial Feeder Housing by means of six 1/4"-20 x 1.3/4" hexagon head bolts, nuts and lockwashers.

(Note from me: there must be a blanking plate and gasket supplied fitted to the Aerial Feeder Housing (otherwise the roof would leak), so that's where the extra gasket comes from (rubber, cork, or fibre of some sort). Bolting the assembly down will be a 2-man job because the roof is in the way - I don't know whether it's supposed to be bolt heads on top (probably) or nuts and lockwashers on top, but it's a fiddle either way.)

(24) Plug the flexible lead of the Aerial Feeder Assembly No.9 into the Antenna Rod "F" socket located on the Seating Plate No.4

I think I have all of those parts (Except for the vehicle!) in the collection, so let me know if you need a photograph or measurements and I'll see what I can do.

Best regards,
Chris.

Progress report : Truck is running . Drives at 40 MPH all day long . I can now start it with the cranking handle . All new windows installed . Needs two CMP seat cushions for the operator’s seats ( 2) . Next : Install control panel for the generators .

[Robert Bergeron]

New windows all around . New copper wire bug screens made and installed on one side . It’s coming along quite well .

[Richard Seymour]

Great work.

Thank you Richard from down under ! Found some parts today that should help me finish the job !
