Radio set No 11 power supply leads.

[Ron Pier]

You are quite right Ben. I should have looked through my archive photos.
Here is an installation in a British 8cwt truck. (flat end panels)

Also a shot of my frame from when it was manufactured. You can see the square frame on top. Also the rubber pads below the top rails and the canvas covered pads under the bottom rails. Ron

Ron, Philip wants details of the carrier tray as I understand his is destined for a carrier installation. Do you happen to have anymore pictures of the 11 set installed in any vehicle, base station ?.

Kevin.

[Ron Pier]

OK Kevin. The way I read Phillips post, he is missing the top PSU frame. I'm behind on where he intends to install it.
The only pictures I have are in this series of 8cwt installation. Same thing just slightly different angles from the one I posted.

I don't know about carriers. But vehicles seem to have the same metal/rubber feet as a 19 set.

Guys, The material for making the tray am I correct in thinking the end plates and cross channels are all aluminium ?, with steel plates rivited where the holding thread fixings attach, as per drawing below, as the threaded stud is welded here ?.

i will take some pics for u ........ the frame is steel.. the aust one..the uk made frame is alu i think

[Mike K]

This may help. this frame is steel , the magnet sticks to it . I think the UK frame is aluminium but not 100% sure. Dont know about Canadian production Mike

[kevin powles]

Mike, it appears The Canadian 11 set tray is All Alluminum, I have talked to few guys in Canada who have confirmed this. Now I have a delima to make an Australian version or Canadaian,? I have a volunteer worker at the Royal Signals museum sending me some pics of one in a glass case there, he doesn't know the country if manufacture but he is going to find out, if British we might be able to confirm the British manufacture method for the tray. Here a pic of it.

I have finished most of the plugs, and will finish fitting the brass inserts to my set. I will provide a drawing of the brass inserts for the 10 pin and 3 pin plugs.

What I have available for whoever needs them is two sets of plugs, which consist of 2 ten pin plugs and 4 three pin plugs. They come without brass inserts and the lid to body gasket/spacers which I will provide a drawing of. These are exact copies as pictured.

They were not cheap to make and a set will cost £70. Please email me if interested in a set.

I have not made any of the two pin plugs.

Looking very nice ! can you tell us the manufacturing process ? How were they made ? Mike

[kevin powles]

Hi Mike, A model making guy made an individual mould for each separate component from the originals, he then resin cast each part, the pouring points were then filed off (located on the inside of the lids and plug upper body).

The plug pin holes were individually drilled also the lid screw retaining holes drilled and taped.

They were then glass bead blasted all over and painted with a plastic high gloss paint to replicate the Bakelite.

Very hard to tell from an original.

Kevin.

I'm also making the plug for the battery connection as pictured as Phillip needs one.

Thanks Ron and Kevin,

The lower frame in the carrier - I assume that this is sitting in a Mk1 carrier?. I'll have to do more research to see what the configuration looked like in the LP2a.

Ron, is the small frame made out of angle or was it pressed? Can you take some measurements?

Regards

[Lynn Eades]

Mike, In reference to your post #35.
The magnet test might surprise you. I believe a magnet sticks to Ali-bronze.

[Ron Pier]

Phillip this is how mine is. 1/16" mild steel plate folded with a slight radius corner to form a 1" x 1/2" angle which are welded at the corners. The outside measurements are 10 1/2" long x 8 9/16" wide. The pictures should help see the cut outs for the leather strap.

I have seen the Blandford British 11 set which is one of only two I've ever seen in about 15 years or more. The musem is only 15-17 miles from me. So if no succes I can go and take pictures. I know the curator Adam Forty quite well, but whether he'd let me inside the glass case?????? Ron

[Ben]

There's a lot of work in making the 11 frame. It needs to be able to change position depending on fit and the pressed holes still all line up and keep the frame square. There's rivets, press tools, folding, machining and welding. 15 separate parts for one frame from memory.

[Phillip]

Ron - Thanks thats a great help, I'll be able to have the angle pressed and will have a go at making up the top frame.

My frame is rusty so I have always assumed that it is steel.

Kevins plug turned up today.

I would challenge anyone to pick it from an original save for its brand new appearance. Many thanks for that Kevin and also for the very detailed drawings .

You are a champ no doubt about it !!!!

Thanks Gina, I haven't forgot about photographing the frame carrier drawing to send. Will do it this week.

Kevin.

[kevin powles]

Here is the 11 carrier ready for painting, one painted it only requires the padding and a couple of missing thackery washers.

Thanks to all those that made the project possible.

Gina, I have sent photos of the drawings.

Kevin.

[kevin powles]

Here is the set fitted.

I see you have the large isolating capacitor on the frame itself - a very important item to have in a vehicle equipped with a mobile wireless set .

Case in point. During the 1950's floods in the Hunter Valley NSW , the army had a few DUKW's rescuing people . Sadly at least one or more of the signallers in a DUKW was electrocuted when the antenna of their wireless set hit a HV power line . Mike

[kevin powles]

Mike, Thanks for the warning, I note I am missing a knob off the 11 set, ANYONE GOT A SPARE?.

Kevin.

Unfortunately that capacitor won't protect you against high voltage lines. It's there to protect the set (particularly the aerial current metering circuits) from low voltage overhead distribution lines (trams, trolley buses, and domestic feeders) that a whip aerial is likely to make contact with. It won't protect against the medium voltage (11kV or 33kV used in England, other countries may vary), since the capacitor is only rated at 5kV DC.

(The WS19 variometer has a similar capacitor built in, but the Aerial Tuning Inductance No.1 or Aerial Coupling Unit 'J' used with the RF amplifier (for WS19HP) do not, and are used with an external capacitor to protect the metering circuitry.)
