Wireless Set No. 52 Canadian - Project

[David Dunlop]

One other thing of note today.

It has been six weeks now since I finished work on the Connectors, Twin No. 17, and I noticed today they no longer smell like popourri. Just a nice old cloth cable kind of smell.

A little more work on the front panel for the Vibratory Supply last evening and this morning.

The last of the paint was removed yesterday and I was able to use a hammer and dolly on the bend at the bottom of the panel this morning to straighten it out.

Then a light sanding to get the last of the paint off the metal and it is now ready for priming. We are supposed to get a break in the cold weather tomorrow, so I am hoping this break will not come with more snow and perhaps the priming will get done tomorrow afternoon.

The front panel has now been primed and should be ready for final painting Thursday onward.

The Knobs, Metal from the front panel of the Vibratory Supply has now been cleaned of all its old paint and is now ready for a coast of its galvanized metal primer.

Notice the ring cast into the zinc around the rim of the Knob. With all the 52-Set components I now have on hand, there are a total of 11 Knobs, Metal to look at and this is the only one to have this ring. All the others have a smooth front face. It is possible Canadian Marconi was contracting with two suppliers for these Knobs, but if that were the case, one would expect to see more of these ringed examples, particularly given the random locations throughout the 52-Set production run that all the serial numbers on the components fall.

Then I recalled the Philco stamp on top of the Power Transformer in the Vibratory Supply. At the time I found it, the simple assumption was Philco was contracted to make these transformers for Canadian Marconi, but is it possible Philco was actually a sub-contractor for the entire Vibratory Supply assembly, and they in turn had a different company casting the zinc Knobs, Metal they needed to fulfill their contact?

The Knobs, Metal for the front panel of this assembly has now been primed.

With luck, I may get some Gloss Navy Grey painting done this coming weekend.

While reviewing some earlier photos I took of the inside of the Vibratory Supply assembly (Reference Post #770), I realized all the hardware in this assembly was sealed with a flat yellow lacquer, For some reason I did not pay much attention to this at the time, but now took the time to confirm all the other components of this 52-Set had a clear lacquer applied to the hardware.

I then rechecked each component chassis, and on each found either a small round CMC Inspection Stamp, either struck directly into the metal somewhere, and/or small black or blue ink stamps showing the metalwork had been inspected and approved for continued processing on the line. No such marks can be found on the front panel plate for the Vibratory Supply. The most likely place for such marks would be the upper rear section of the panel where it would have been easily seen. As per the last photo in Post #778, nothing shows.

It makes no sense to me that Canadian Marconi would have wasted money on a section of the production area making Vibratory Supplies to have a different coloured sealing lacquer from the rest of production, but if Philco was making these Vibratory Supply assemblies for Canadian Marconi, the visible evidence fits that theory.

I wonder how well the executives of each company knew each other during the war?

The finish coat of Gloss Navy Grey has now been applied to the Vibratory Supply front panel and its Knobs, Metal. This will take about three days to reach a state of ‘soft cure’ and another two to three weeks thereafter to attain its final ‘hard cure’.

That’s a good thing because there are lots of other tasks to accomplish in the meantime.
