Mountings, Carriers, No. 1

[Bruce Parker (RIP)]

Dave, the wireless table in the HUW is not 1/2" plywood. The table frame is 1" angle and the wood plus linoleum sits on the upper face of the angle on the bottom to flush with the top so is 7/8" thick combined.

7/8" table, plus two strips (each 1/16"), plus the 1/8" foot, plus 3/8" for the nut and lock washer and it means at least 1-1/2" bolts.

Thanks for the quick clarification, Bruce. Interesting that an October, 1944 publication covering the truck installations omits the variation for the HUW wireless table. The two different lengths make sense now.

Cheers,

David

I am currently restoring the radio bench for my MWR and the bench top is made from three planks which are 1" thick. This might account for the longer attachment hardware.

Thanks for posting that info, Simon. The more knowledge in the pool, the better!

Thanks for that. I fear the flow of information will all be one way though.

I have so far cosmetically restored my No 23 breadboard(which was unpainted from new), the EKCo Mk III 19 set, Pye PSU, variometer and control box and am gradually acquiring the missing bits to complete the installation.

I know that each set of the shock absorbing mounts have two metal strips which go either side of the bench top. I have assumed that these are 1" wide and half an inch longer at either end. I have used 1.5mm plate. Is that about right?

Hi Simon.

One inch x 11-5/8 inch x 1/16 inch. End to end they line up with the ends of the Bridges feet, if that helps at all. Not sure if they were originally steel strapping or punched from sheet steel. The Canadian ones I have were made by RCA and bear their round black circular stamp and a larger circular MECH INSPEC stamp with the inspectors number in the middle. In my case an '11'.

I have seen similar stamps on various RCA Canada 19-Set chassis parts, so suspect RCA had a major sheet metal production facility somewhere during the war. Finish is a dull grey zinc coating.

I'd post pictures but our iMac is in the shop at the moment.
