Wireless Set No. 52 Canadian - Project

[David Dunlop]

The installation of the grounding strap and lower right front panel bracket were pretty straight forward. The one thing to be wary of, however, is that over 80 years, the holes in the wooden case for the hardware have dried out and this results in slightly larger holes the hardware feels a bit sloppy in. I used a small square block of wood held against the face of each front panel bracket to keep the brackets square to the case at the hardware was tightened. this will ensure the holes in the brackets line up properly with the front panel hardware when that assembly gets reinstalled.

The centre upper and lower front panel mounting brackets have now been cleaned, re-plated and reinstalled.

The last two for this part of the project are the upper left and right brackets and hopefully;;y I can get them done on the weekend.

Beautiful work as always.

Thanks, James. I am happy I can still at least muddle along.

Today I got the last two front panel mounting brackets cleaned, zinc plated and reinstalled in the upper corners, so I am now finished with that bit, but still have a little new research to sort out, hopefully in the next week or so.

In the meantime, I plan to work on the two Aerial Input Terminals, located on the lower rear sides of the case. Both seemed OK when I disassembled and removed them last year, but it's time for a closer look.

I got the right side Input Aerial Terminal disassembled cleaned and re-plated this afternoon. The main component of this assembly shows up in the Master Parts List as:

STUDS, Brass, Special, ANF 10-32, 1-21/32 inches long, No. C1 ZA/CAN 8048

It is machined from 1/4-inch brass bar stock and once the wing nut is fitted, the end of the threaded shaft is mushroomed slightly to prevent loss of the wing nut. It would have been easier to deal with the shaft being drill through and a small D-Ring fitted, as you have to carefully press this stud assembly out of the brown phenolic resin plate it is fitted to in order to get the entire assembly free from the coil case.

I discovered the rear edge of the resin plate showed signs of the bcd saw blade bucking when the plate was cut, leaving some light tan marks on the edge. A thin coat of clear nail polish reduced the visibility of these marks by about 50 % so I was pleased you can still notice the damage but not so glaringly any more.

I was able to reinstall the right side Aerial Input Terminal last evening and once the Stud assembly with its captive wing nut was back in place, made an interesting discovery.

I had assumed the mushroom effect applied to the tip of the shaft the wing nut moves on was simply achieved by a sharp rap with a hammer. However, as you can see in the photo of this assembly back in place, the newly cleaned and re-plated tip of the shaft revealed it had been struck with a small cross punch to achieve the mushroom effect. I was pleased another little detail finally came to light...literally.

Hopefully, I will be able to clean, re-plate and reinstall the Aerial Input Terminal on the left side of the coil case today.

A productive afternoon today after all the errands were out of the way.

The left side Aerial Input Terminal assembly was stripped down, cleaned and re-plated. At the start of this I cleaned and checked the end of the stud behind the wing nut, and sure enough, it also revealed the mark from a cross punch used to mushroom the end of the stud.

When this terminal assembly was reinstalled on the left side of the coil case, I realized the only item left to deal with was the large Aerial Output Terminal located on the upper left side rear corner. I pulled it out of storage to see what work was required on it and was pleasantly surprised the metal work on it was nickel plated and in very good condition. A quick disassembly and cleaning and I was able to reinstall it as well. That just leaved three sets of hardware to clean and re-plate for the coil case and those can wait until I deal with the now pending work on the actual front panel of the Coil, Aerial Tuning No. 2 A.

That should be fun.
