19 set shock mounts .....

[cletrac (RIP)]

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.

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, 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!

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.

Kevin if you manage to produce a spare set from the Australian company, I'd be happy to chip in. http://www.mackayrubber.com.au/contact/

According to Bruce's drawing, the new stuff is 17mm wider. So maybe the feet can be paired back by 8mm a side and still look ok.

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.
