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.

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

Wow - are these the same dimensions?

Cheers

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

[David Dunlop]

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.

[Ron Pier]

I got the feeling that Bob was talking about something different when I saw Bruce's post. However both types of shock protection are interesting and I'm learning all the time. Good to see that lynn has found someone who actually makes the bonded rubber mounts in strip form. I haven't checked the width of an original yet, but I guess 1 length of 150mm could make a set with spares?

Ron

[Lynn Eades]

Ron, it looks like they are made in different widths. if i am reading it correctly they are made an inch wide, and un drilled, so they could be trimmed on the inside and look pretty bang on. The Mackay company has been making engine mounts and rad hoses in Australia for many years. Who knows, maybe they were the original manufacturers for Australian radio set mounts? (if they were made here)

That's the mounting (well, half of it) for the No.3 (or 23) and No.25 WS19 carrier. (So that you can have a demountable "truck & ground" station.)

There's a variant with doubled shock absorbers (second pair mounted upside down) for the (British) WS19HP installation on Carrier No.25 - the RF amplifier is mounted on top of the set and needs the extra support. Because the combination is top heavy there's an additional shock absorber with a plate on the base and an L bracket on the top, the plate fits to the vehicle side and the L bracket is attached to the top of the amplifier with the usual three screws.

I think the actual rubber mounts are "Shock Absorber, Bridge, Mk.II" - they were also used by the Air Ministry because I've seen them on a T1154 case before now, possibly for vehicle or patrol boat use. They are a "Multi-Purpose Part" and used on a great number of radio mounting frames.

The canvas strip or moulded rubber pieces that fit between the set (and supply unit) and mounting frame are to protect the set case from the screw heads on the frame - otherwise you'd quickly get holes in the fairly thin set case. They have virtually no damping properties!

Chris.

[kevin powles]

Gents, How do we order from the Mackay company, I can't see a uk supplier, there is also no prices listed, I think I could make 12 of the mounts from there 300mm strip they do. But I confused as to which of the two types is the same as the 19 and 11 set mounts.

Some one above your post says the rubber shock mounts weren't used on the No.23 carrier. Actually, what you have in your picture are the rails that use those rubber mounts to secure them to the vehicle wireless table, then the Carrier No.23 slides into them making it a vehicle mount, quick release kind of set-up.

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.
