Wireless Set No. 52 Canadian - Project

[James D Teel II]

Oh that's a very nice hydrometer!

It did take a while, James, and I wonder sometimes passing on items that show up at the wrong time, price or condition. I did pass up another one in the UK a week earlier because it had a badly stained case. I guess I chose the right wine to toast the Gods with this time.

Not just stained: there was severe acid damage to one end of the lid.

Definitely.

I first posted on this back in 2022, on Page 27, Post #782, when I first got enough useful information sorted out.

Since that time, this project has been plodding along and as I found situations anywhere in the 52-Set where none original washers had been installed, made notes of the locations so they could all be replaced once I had sourced the required correct washers.

For the most part North American Standard Shakeproof Washers (usually called Internal Tooth Lock Washers) are easy to find but in the modern, prepackaged hardware world, are rediculous in price, often working out to a dollar or more each. While reaching the web again recently, I discovered Graingers, here in Canada, carry many of these washers in Lots of 100, for typically less that $4.00 per Lot, and they have a store just 10 minutes from home. Bonus!

I have been ordering these washers over the last few weeks and my wife donated a surplus crafting supplies box to my cause to store them in. The box was a great choice because the dividers are fully molded into the case so the smaller washers cannot slide between the compartments. And rather than labeling each compartment I simply did a single ID Sheet on the computer to pop into the lid, which can be easily changed out if and when needed.

I picked this item up today at our local Prairie Command Spring Get Together.

My days of WIRE 5 work are over, but this chimney will be cleaned, primed and painted gloss white inside and an appropriate CMP green for 1944 on the outside. The 9-inch square steel plate on top, that has been factory punched to accept a 19-Set Aerial Base for the A-Set will be replaced with a 9-inch square of 1/4-inch thick brown phenolic resin plate and the vehicular aerial base for the 52-Set mounted in place of the original.

Put a couple of angle brackets on my Wireless Room wall to hold the chimney and the 52-Set Aerial Base can be displayed effectively. So the plan goes at this point.

When removing the front panel from the Coil, Aerial Tuning Unit No. 2 A, it is important to remember the Tuning Counter Dial assembly is fitted to the Front Panel and will come off the Coil Chassis assembly with the front panel. If the Tuning Counter gear box gets bumped at all, the calibration between the dial readings and the actual position of the tuning V-Wheel along the coil will be lost. Not a good plan.

Before removing the front panel, it is best to dial the counter back down to its ‘0000’ position, which places the V-Wheel against its Stop at the left end of the Coil. See the first two photos attached.

The interface between the Dial Counter gear box and the Coil gear box is a simple, black Bakelite disk, free floating between the two gear boxes. It will easily fall out when the two gear boxes are separated. See the 3rd photo.

The simple solution is to tape the Bakelite Coupling to he Coil Gear Box arm, so it stays with the Coil Gear Box on the chassis. Then, also tape the Dial Counter Drive shaft to the back of the Dial Counter to keep the Dial Counter held in its ‘0000’ position. See the last two photos.

With all this prep work done, the front panel on the Coil, Aerial Tuning No. 2 A can be removed from the coil chassis.

The Front Panel assembly is mounted to the Coil Chassis assembly by eight round head, slotted, brass, zinc plated machine screws. See the first two photos.

The red highlighted ones in two vertical rows are made up of 10-32 x 3/8-inch screws with matching Shakeproof washers and hex nuts. The screws pass through two sets of holes in the brass angle frame of the sides of the coil chassis and are secured with the washers and hex nuts.

The two yellow highlighted screws across the lower edge of the front panel are 8-32 x 3/8-inch and thread directly into the two brass angle brackets mounted along the front edge of the bottom plate of the coil chassis. These two arrangements are shown in the 3rd photo of my spare parts coil assembly.
