Is it possible to send me all the Shilo pictures in hi res to my home email address???

That way I can enlarge to my heart's content and make out all the lettering and details.

No rush.

will send you a PM with the address.

Cheers

I may have shrunk them a little too far so I could post them without issue. They are on a DND computer. I know we have issues trying to send and receive photos that are too big on that system, but sure, we can give it a shot. I'll have to figure out what the parameters are.

When I was in the box today I noted a few things that aren't right. For instance, a lot of the conduit is copper plumbing with soldered joints. Not so sure that is correct.

The small white box located on the right side wall between the windows is the Fuse Panel and electrical distribution hub for the interior wiring. A standard piece for all 2K1 and 2K2 Wireless Bodies. On the inside of the lid would have been the Wiring Diagram. The panel inside the fuse box does contain a single selector switch to flip charging current between the two radio battery units, but it is not a charging board per se. The Charging Board with the four selector switches was stored in a rack on the underside of the wireless table when not in use. The large fuses visible in Rob's photo protected the main battery charging circuit. The smaller fuses protected the overhead lighting and power ventilator circuits.

Hi David

What was the no 5 charging board used for and when and what was it mounted to for use......

,,,and if the no 5 board is hard to find where do you even start to look for the proper one switch board that fits inside that box......?

Getting korn phused...!!!

PS..... and I have seen a copper grounding strap around the wall and the one we have at the barn is an aluminium grounding strap!!!!!

Took me a while to sort out as well, Bob, and I came at it from the opposite direction, finding the fuse box first and assuming it was the charging board. Let a whole whack of No. 5 boards pass by before realizing they were two completely different things and by then the boards had entered the Land of Unobtainium!

What you see in the Fuse Box is a complete, unique package, but does perform a bit of what the Charging Board does.

The Charging Board (and if anyone has a manual or working instructions for it, please post in the Wireless Section) was a piece of the kit the wireless team humped into the woods when they went remote with the wireless set, along with a chore horse, two cases of batteries and all the other easy to carry pieces to operate. Not certain of the details of it's operation but suspect it allowed for a number of combinations of power feed to and from the chore horse, batteries sets and wireless all at once, or various controlled patterns as needed.

When not needed, it was stored under the bottom of the wireless table: slid into two steel rails. If you look closely at the photos Geoff posted of the wireless table of tubular steel design, that, is an original wireless table for the 2K1 and 2K2 Wireless Bodies. The four legs would end on the floor on triangular steel plates with holes in them to bolt to the floor. Bolts came up from underneath the vehicle and were nutted inside the box.

It has been a while and I cannot find my photos of the wireless tables in situ, but if memory serves correctly, on the left side (?) of the table there was a large deep drawer which probably stored the spare parts and valve boxes for the wireless set. Either end of the wide open space under the table had the two flat pressed steel rails the charging board slid into. Under the table Geoff posted, the drawer has been removed and a pair of wooden rails have been added.

Backing up to the fuse box again, it worked to control the power distribution and prevent overloads or shorts burning things up, and also allowed flipping the charging current between the two sets of wireless batteries stored in the wooden chests on the floor in the front right corner of the box. In the event a fuse blew, the knife switch allowed the circuits to be disconnected for the fuse change, or any quick trouble shooting, without having to turn off whatever generator was running. I do not believe it allows for running the wireless directly from the generators. Just the batteries.

The generator box, which is a bit of a black hole since it is painted entirely green inside, not white or grey, has a set of three switches with a metal guard plate on the side of it that faces the front of the box. The first two are used to start and stop the two generators that have been installed. Remember, the Army installed them, not Wilson Truck Body. It would either be a pair of chore horses or an Onan AC/DC rig on the floor and a chorehorse on the upper shelf in the 'portable' position. The third switch I believe was a 'Mains' switch that isolated any power from getting out of the box. The outside of the gen box door had a large stencil warning the door must be closed and the two outside hatches open for proper ventilation when the generators were running. Green inside the gen box to reduce the visibility factor when those hatches were open. The edges of the gen box that mated up to the plywood walls of the wireless box, along with the perimeter edges meeting the floor, were lined with what appears to be fabric style fender welting to seal for fumes. Not much of that is usually left after things start leaking for decades. Also, where the armour cables exit the side of the gen box, these holes were sealed with a compound that looks a lot like Glazer's Putty. Maybe there is an Electricians version. Soft enough to apply but sets up rock hard.

As for the big copper buss bar, Bob, they only ever came copper. Strongly suspect somebody eventually saw dollar signs for all that copper and wogged it, substituting the aluminium you noticed.

Hope that helps a bit, Bob.


Cheers for now,

Thanks David

Grant radio box is fiarly complete with the corner box..... some refer to it as the icebox/refrigerator...... and the tube steel table is still in place.

However, the ceiling plywood is almost tooching the floor and the walls are also coming off due to water leakage. The Box is now stored inside a dry canvass Winter shelter resting on a spare cab 13 frame.

Grant also acquired the disassembled guts of another box...... and I vaguely remember the 3 switches on the icebox...... he has bins of odds and ends which may not start to make sense.

Will have to verify if the table has the underneath brackets. He did score a No 5 charging board but I fear we have the wall white box BUT not the innards.

I would hate to have to replace the copper grounding bar at the price of copper today. Not sure if the aluminium ground bar is from the spare box or if the good one still has it in place.

will try to seak in a peak over the week end and maybe take some pictures.

Was there ever a manual for the specific installation of the 19 set in the 2K1 box...?

We have yet to start on the restoration of the box.

cheers

Bob. I agree a copper bar would be pricey, but possibly doable. Be interesting to cost out what a correct sized piece would be with the appropriate bends in it. The rest is just hole drilling to locate the standoff insulators and the terminal posts. It was copper because of the low electrical resistance it offered. Brass might be just as expensive as copper, or perhaps more so. I personally would not go near aluminium to save my soul after all the negative feedback that surfaced from it's use in home wiring a few years back.

Get yourself a copy of "Wireless Set Canadian No. 19 INSTALLATION INSTRUCTIONS For TRUCK AND GROUND STATION". It was published by Philco in the USA in October 1944 for the Canadian Military and covers everything you need to know about setting up a Mk II or Mk III 19-Set in any of the 2Gx or 2Kx 15-cwt Wireless Trucks and the HUW. There was a flood of these NOS manuals hit the civvy market back in the 1980's and they still pop up from time to time at flea markets and such.

One thing I would suggest, with the interior plywood you have still in place is study the hell out of it! Photograph it all until you are ready to scream and measure where all the mounting screws went. It they are original and still there, they are easy to spot: slotted, curved head sheet metal screw about 1/2 to 3/4 inch long, surrounded by a small finishing washer. If you have a second wireless box handy with original plywood still in place you will discover something interesting. The mounting screws for each piece of plywood are all in exactly the same place on each piece. It took me a couple of full Saturdays exploring all the boxes at Princess years ago before that lightbulb went on. Wilson Truck Body was running a full blown assembly line building these boxes with all the related demands for efficient use of hardware and reliable consistency of product.

I suspect they took advantage of cabinet maker/custom millwork shops and their equipment to make the pieces of interior plywood. One of the first puzzles I had looking at the interiors was why there was a seam line around the walls at the midpoint half way up. Why didn't they just slap a four foot piece of plywood around the bottom and fill in the upper portion with a smaller strip? Then I noticed the consistent placement of the original hardware on the walls from box to box. Some years later, while working at a local window and door manufacturer, I learned about the amazing machines the millworks industry has available for mass manufacture of large pieces of wood, predrilled for hardware. Think IKEA RTA furniture today. These machines do have size limits for the wood they can handle and back in the 1940's the size limits probably dictated the size of plywood to be worked.

So basically, all the pieces of plywood for the insides of these boxes, and all the trim millwork that covered the plywood seams, would have been pre cut and predrilled, ready to be mounted inside the boxes at the appropriate point in the assembly line: speed, efficiency, consistency. I suspect a similar pre drilling process was used with the roof assemblies to ensure all the pieces that had to be mounted on it were in the same place over and over again before they were dropped down on the open box shells.

By the way, the trim strip millwork covering the plywood seams is still a standard item at Windsor Plywood and a few other woodworking supply shops around town in these parts.

Gotta scoot. There is a snowstorm underway I have to sit and watch.

Dave, I question your theory about the charging board. In 2K1 Wireless I think it mounts on the right side wall between the chorehorse 'fridge' and the switch box. What's under the table is rails for a sliding table and two drawers. The charging board was stored under the wireless table on HUW vans. The interior of the 'fridge' was exterior colour because the chorhorses were meant to be run with the outer sliding doors open (carbon monoxide) and hence cam painted as per the rest of the truck.
