19 set shock mounts .....

[Bob Carriere]

Hoping there is sufficent interest to create a separate thread.... that will be easier to search for in the future.

I have a 19 set that is on need of the four corner canvass / rubber shock mounts.

My set up as the typical wooden board with the metal tray and the canvass hold down straps..... no corner shock mounts.

From what I has een on other sets it looks like a heavy canvass.....almost like a fabric fire fighter hose thathas been flattened and dip in some preservative.

As Rob pointed out they are hard, dried up and offer hardly any shock absorbing capacity.

I last saw a full set of four on Ebay for $100.00 US ...... great for autothenticity but not for the well beign of the radio.

What have others used to replace, reproduce, rejuvinate, substitute .....for the corner mounts....?

Any ideas how they were made originally... canvas obviously but dipped in what???

Would a section of military web belt be adequate cut and folded 90 degrees...but not very resilient to shocks...

A section of fire fighter canvass hose..?

How about a section of flat rubberized agrcultural belting used on the old trashing machines....some are canvass impregnated with rubber...... or a oiec fo rubber conveyor belting.....

Ideas...suggestions..

Cheers

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

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.

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
