Wireless Set No. 52 Canadian - Project

[David Dunlop]

This is almost a simple topic as only one modification shows up in the listing I have for the Sender. Naturally, it is Modification No, 1, for the installation of the modification card holder.

This is where the 'almost' above comes in.

The instructions state a metal plate is to be removed from the left rear corner of the chassis, holes to be drilled into the plate, the holder attached and the plate returned to its position on the chassis. Problem is, there is no metal plate on the chassis in that location, either on the rear or left side of the chassis. I checked the Sender chassis I have and all the photos of the Sender in the manual. No such plate.

There is no room at all on the top of the chassis to mount a card holder and I could see nothing anywhere when looking through the chassis. Curiosity got the better of me finally and as a last resort, I carefully turned the chassis over to have a look at the bottom. There it was, as per the attached photo. And there was a modification card inside stating the modification was done in 1947, but no mention of the Shop where the work was done.

I have not really detailed out the parts sequence for restoration work on this project just yet. The Carrier No. 4 still needs to be looked at up close once it arrives, but other than that, all I know so far is the first priority will be to finish work on the two receivers. That work is already three quarters completed, so best follow through with it.

My suspicion is the Supply Unit may end up being the last item tackled. I still have two single conductor connector cables to find for the main set and until they are found, I do not want to risk damage to the Sender, Supply Unit or both by ad hocing anything foolish. So buying more time by restoring the supply last makes sense from that perspective.

I was initially hoping the panel of the Supply Unit could be polished back down to the right shade of paint patina to blend in with the two receivers, but now that I have cleaned the grime off and had a closer look, that will no longer be possible.

First, too much paint is completely gone from the bottom of the panel. Nearly an inch, and in that same area, the bottom inch of the Receiver Vibrator Supply Module has been bent inwards just enough that it will have to be tooled carefully back to straight. I don’t think there is enough ‘careful’ available in the paint to prevent it from spalling off when that work is done.

The final factor in deciding on a complete restore of the supply panel was the discovery of just how incredibly sloppy the decal application work was during its 1966 shop refurbishment. Take a look at the attached factory photo of the supply decals from the manual, and compare it to the work done on this supply. Yikes!

I think some good water transfer decal software is on the horizon for me at some point.

I recall reading about creating water transfer deals by printing. One issue is with printing white - most printers rely on white paper rather than actually printing white so you either need to find one of the rare printers that deposits white to the page or print on transfer film that has white background (and cover every scrap that you don't want to show white (including around the edges)).

Hi Grant.

Yes. I suspect a bit of research will be involved when I get to that point. And very likely, a new desk top system.

Something else I just noticed reading your response. The decals used in the 1966 rebuild have a similar overall size to each of the originals, but there is a lot more black surrounding the words. The decals in the manual photo are a match in surround size to the decals on my receivers, and the Sender.

Hmmm. I think I will have to put the black light on the Supply Unit and Sender tomorrow and see what, if anything glows, and in what colours.

A really quick Google says that waterslide "paper" to suit either laser or inkjet printers exists with either white or clear background (i.e. four different types of "paper").
At one time there were dye sublimation printers made by ALPS that could print white but they seem to be out of business...
There are listings on ebay for refurbished Alps printers for waterslide printing - eg. https://www.ebay.ca/itm/Refurnbished...IAAOSwRJ1Zn~QZ There are also results for Windows 10 drivers for the Alps MD-1000. However, specialized orphans can be relatively expensive and the consumables can also be out of line compared to more widely used and current product.

Could a very light canary yellow or very light grey be substituted for the white color?????

The last major piece of this project arrived yesterday afternoon via FedEx. Quite an impressive beast when you get it unpacked!

Main plan for it at the moment is a basic clean up of all the years of dirt and grime accumulation. Sadly, it underwent a 1960’s era repaint in which all original finish was stripped and NATO green applied. Like the Remote Receiver Case I found, even the inside of the carrier was painted. In the Remote Receiver Case, the paint inside was thin enough the two grounding springs in the upper back of the case were still capable of grounding the case to the chassis of the receiver. The paint job on this Carriers No. 4, however, is so thick inside, I don’t think any of the six grounding springs could work properly again.

Once cleaned, I must read up in the manual about the correct way to reinstall the three components. Jacques Fortin brought this point to my attention, as it is a very tricky task. A 52-Set definitely makes for a very interesting learning curve!
