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.

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.

Ron

Material used
 

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 ?.

Kevin.

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

pic
 

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

Tray.
 

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.

11 set
 

The Blandford example is a E.K.Cole UK built set . Some friends sent me a movie of the museum years ago... the 11 set on display is in a glass case , this is because its rare as hens teeth . Its a mystery why only a handful of these survived ......... many were lost by the BEF but not 18,000 which is the production total , so Lou Meulstee says . Apparently the Germans printed a manual for the 11 set , they had captured many of the sets .

The Aust. version was a disaster in the tropics .. the cotton insulation was a great home for fungal growths :doh: BTW the Aust. sets have a date scribbled in pencil on the back of the main tuning dial, Ive seen this on quite a few sets . The production ran from 42 into early 1943

I have used a 11 set on the ham 40 metre band , once was enough .

Hi Mike, Thanks for that, great info you have and interesting in sights. Hope the guy at the museum comes through with some pics but he did sound vague on the phone and in his words "extremely busy" doing what I don't know, things most likely move at a fast pace in these museums :confused.

Kevin.

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

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

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

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.

11 Set Frame.
 

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. :eek:

11 set plugs
 

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.

nice
 

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

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.

Plugs
 

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

Kevin.

book me in for one as well please.

Hi, I will get you one made, the more people who wants them will keep the price down, most the cost is making the mould. But I suspect the world demand for 11 set plugs you can count on one hand. :)

As used on the Amplifier, RF, No.2 (for the British WS19HP) with 12V input, or the R107 for AC Mains[1]?

You're on the wrong side of the planet from me, but I've got a spare one somewhere and it shouldn't cost too much to post.

Chris.

[1] If you're doing that, bolt the earth conductor solidly to the chassis somewhere, please!

The British one will be steel.

Britain had a steel industry (also Dunlop and similar rubber companies), Canada had/has shedloads (technical term) of hydroelectric power, aluminium smelters (due to cheap electricity) and forests. This caused interesting variations in the materials used for WW2 hardware. British made Telephone Sets D Mk. V have steel cases, Canadian ones are Aluminium. The British made Aerial Base No.8, Mounting No.3 is a thick rubber moulding (later ones were a steel donut with rubber gaskets), the Canadian one is plywood with cork gaskets. The "Piece, Packing" for the WS19 variometer can be Bakelite (UK), Rubber or wooden (Canadian), pressed steel (US) or cast aluminium (post-WW2 Italian).

I'd imagine the Australian carrier is also steel, since they made the WS19 aerial mount N0.3 (the very tall one) out of steel with a steel spring where everyone else used rubber and aluminium.

It's all down to availability of materials at the time.

Chris.

Chris the 12V plug

Gina,
Do you still want a plug casting?, I am getting one made for Philip. I don't need one so the guy is only making one, but if you need one it will bring the price down. I can do all the machining and hole tapping. It will come without brass inserts but I have a drawing for making these.

Kevin.

The 2-pin plugs should not be that difficult to find, since they were a "multi purpose part" used on a variety of sets (WS11, WS19 RF amplifier, R107, DC-AC converter for the Typex machine, etc.) and were still current issue in the Larkspur era.

The 3-pin connectors are more difficult, despite being used on the R107 (muting plug) and a lot of Line kit (mostly carrier telephone stuff). (Anyone with an R107 needs one of these to blank off the muting connector which has 250 volts on the exposed pins!)

Some Dutch eBay sellers had the 2-pin version as WS19HP power cables, and they may still be around somewhere.

The moulded replacements for the "domino" sockets are a work of art, but it would be much better if the contacts could be include at moulding time - they're only a brass pin with a central hole (tapped at one end) and a groove with knurled bottom to retain them in the body. I don't know how complex the moulds are, but it should be possible to incorporate the contacts before filling the mould.

Chris.

OK, on the assumption it's the same as the WS19HP one, I have a NOS example and will calculate you a postage cost tomorrow (I hope).

Chris.

Hi Kevin if Chris is good to send me one then I am ok .

Hey Chris send me a Pm as to costs... do you have a pay pal ??

Power plug 38 AFV
 

Any chance of getting the power plug and socket made for my 38 AFV set. Some one hardwired a cable inside the radio and took out the socket. I think the plug is identical to the WS19HP 12 V plug but about half the size.
