19 set shock mounts .....

[Ron Pier]

I'm not sure about canvas? I thought they were bonded metal/rubber. I'm sure I've seen them un-painted to expose the black rubber. These are the ones on my WS11 set.

Metalastic exhaust mounts from something like the early Mini cars will do an excellent job.....But don't look right of course. Ron

Hi Ron

Those look like my shock mounts ! But you only have 2 !

In the early 1980's I used to browse at HAM RADIO SUPPLIES in Highett st Richmond . It was in an old wooden building, just about ready to fall down, the roof leaked . Imagine my pleasure one day, after I found a box full of those shock mounts , must have been 50 of them .

In another box I found about 40 of the rubber B set antenna mounts for the 19 set . These i bought for 5 bucks , the whole box .

The old chap on the counter liked me for some reason and he would sometimes give me the key to the upstairs storage room . In the storage room were boxes full of 11 , 19 and 22 set valves ... all new in their wartime packaging . The valves were 50 cents each .

Kicking around on the floor were 19 set spares boxes , these would be a dollar each . In the side room there was a huge pile of 62 set leads and accessories in a huge tangled mess on the floor .

The store was one of those long forgotten Melbourne treasures Mike

19 set carriers (and similar sets like the No.22) used pads between the set cases and angles on the rails. These pads were originally rubber(pic 1) and latter canvas (Pic 2). The were to snug the sets in the base rather than for shock protection.

These are troublesome as they are almost always broken due to deteriorating rubber. Even NOS ones fail if you put a set on them. To fix them (or reproduce them) what I have done in the past is bolt the two bottom angled pieces to a metal plate at the correct horizontal spacing. Then I put a threaded metal rod in the centre with a bolt at the right height to position the central U shaped piece. This rig holds the three pieces in their correct spacing without the rubber. I then welded the pieces together (with a little filler and careful to have the weld within the joints) then filled the spaces with black silicone. Dry, cut the sides and you're ready to go.

Similar mounts are made commercially and available online. A quick google search led to this: http://www.vibrationmounts.com/RFQ/VM110225.htm

Interesting. The second one in their size chart (V11Z49MKE030) would probably do. The hole spacing on the bottom is 85mm instead of 95mm on the WW2 ones so some adjustment on the mounting holes on your vehicle would be required, and they are 30mm wide (instead of 22mm) which you could live with or shave down. The height is right on.

[rob love]

That was the one I was figuring on as well. You might be able to elongate the holes by 5cm each and obtain the required spacing.

There are other manufacturers of similar mounts in inches rather than mm. Perhaps some of them come even closer.

These mounts aren't cheap mind you. They run around $15 or so each. But the fresh rubber with modern bonding might be worth it.

Mike I have a complete set of the correct mounts for my 11 set in the Morris. But my Jeep 19 set has those Mini car mounts. I don't suppose you have any of those correct type left do you? Ron

Could some one put up a dimensional drawing of an original off the 11 set radio tray or no 21 or 22 19 set carrier.

They look easy to make, I think if you had the Steel grit blasted, de-greased and stuck on some cut rubber with car windscreen black bonding compound and left in a hydraulic press to cure they would stick.

The trouble with buying the ones suggested, you still have to cut both sides to get the 22mm diameter, then elongate the hole after paying $15.

I think I can make some for the price of some compound which I need to buy anyway to stick my bump stops on the Centaur tank suspension.

Stick like s**t to a blanket I'm told.

Thanks Bruce, will have a go at making some after I have finished the 11 set tray.

Do you think these are the same for all three radio holders, 11 set 21 & 22 carriers ?.

Many thanks Kevin.

[Lynn Eades]

Made in Australia. Close! May be a rubber company is still doing the exact thing?

Yes they are all the same. Colour would change: black-green wrinkle circa 1941/42, brown circa 1943/44 and O.D. circa 1944/45.

I have a few feet left Ron , but I need them myself

All of the rubber B set mounts have gone..I gave many of them away

I don't think this thread has been hijacked, however I am also not certain it has headed in the direction Bob had originally hoped for it.

If I read Bob's initial post correctly, he owns a Carrier No. 23 for his Wireless Set. This carrier was never equipped with the composite rubber/metal shock mounts that fastened the carriers No. 21 and 22 to a vehicle. It did, however, come with pads (as per Bruce Parker's Post of pix 1 and 2) designed to fit over the four angle iron rails the PSU and transceiver rested on, when strapped to the carrier.

I am curious, Bruce, if the rubber pads in your first picture are plain flat hard rubber: either one large angled piece of rubber, or four separate strips? The ones on my Carrier No. 23 are of a molded foam rubber design, right angled in shape. The surface of them that is in contact with the wireless equipment is smooth. The surface that rests on the rails (the undersides) have angular recesses cast into them to fit the rails, and within these recesses are six round depressions intended to fit over the screw heads used to mount the rails to the carrier chassis. If these are different than your rubber ones, Bruce, then there are at least three variations of these pads out there.

Regards,


David

Dave Page, a chap from NZ living in the USA down in Alexandria VA, made up some repros about two years back for his Dingo restoration. I got a set from him to mount in my Humber Mk4.

Thanks to Dave's efforts, we now have a DIngo and an Armoured car in the club that can actually talk to each other with the 19 set.

Theoretically at the moment as we both need to get our amateur radio licenses.

I can check with Dave to see if he had any left for sale or if he had enough interest, he might run up another batch.

I think the price was about $70 USD for a set of 4.

These are NOS ones for a 19 set. They look to be the same as the 11 set used. I think 4 of them will go in my 11 set box of stuff.

Bingo, that's them. Still two patterns out there so far. I imagine the change from rubber too web was that because of that early war rubber shortage.
