Wireless Set No. 52 Canadian - Project

[David Dunlop]

It took just over two years to finish this Ground Terminal, but I did so this morning.

Sorry to have bored your gizzards out with this little sub-project, but it will, eventually, tie in with the restoration of the 52-Set and help keep all the electrons happy when the time comes to put them all to work.

I now have the replacement bracket clamped to the side of a piece of 2 x 4, and I have the mid-section oriented perfectly flat.

The plan is to use this setup for the creative painting ahead to try and blend this new bracket into the original interior of the toolbox.

With finally getting caught up on most of the yard work today, I was able to put some time in this evening to give the new tool box bracket an initial coat of Flat Olive Drab paint to start the process of hopefully blending it in to the rest of the tool box.

A bit hard to tell where this is all headed at the moment, with the paint still largely wet. I should have a much better idea tomorrow after its dry.

As it turned out, there were just two small adjustments I felt were needed with the paint work on the replacement bracket, to make it look at home in the tool box,

I added paint to the left edge of the bracket as this paint had largely survived on the left edge of the surviving front bracket.

I also added some horizontal and vertical scuffs to the upper face of the bracket where tools moving passed it over the years would have worn away a lot of the paint. This also brought it more in line with the front bracket.

The enlarged hole I had drilled in the bracket did indeed come in handy when installing the bracket. It allowed enough wiggle room to get the bracket properly aligned with the original paint shadow on the back wall of the box, as well as get the flat of the bracket level.

So I now have a toolbox for the 52-Set with a complete pair of interior brackets and wooden partition once again in place.

The next step for this part of the project now will be to figure out how best to fill in the screw holes on the exterior where the original filler hiding the countersunk screws has either fallen out or worn away a bit.

I picked up this small tub of Glazing Compound the other day to be able to continue work on the Tool Box. From what I can determine from the three wooden boxes/cases forming part of the kit for the Wireless Set No. 52, the Cabinet Division of Canadian Marconi Company were using a product in 1944 called Glazing Putty to backfill the countersunk screw holes in these boxes/cases, prior to final assembly and painting. I can remember my Dad and Granddad using Glazing Putty in the 1950’s and 1960’s, when single pane glass replacements in a house were still common household practises and you could get small replacement glass panes cut at your local hardware store. From what I remember, the Glazing Putty back then was a soft, pale beige clay-like material sold in either pint or quart tins, and at one point even in heavy-duty clear plastic pouches. It had a smell of linseed oil about it and could be easily formed into pencil-sized strings one would press into the edges of the glass frame and shape off with your wet thumb into a nice 45-degree angle. The oil would be drawn into the wood of the window frame as the putty set up and you could then paint or stain over it with the oil based paints back in those days.

Seems that original putty has gone the way of the Dodo Bird today. A search for ‘glazing putty’ now turns up this stuff and all sorts of automotive body shop ‘bondo’. But I think this product will work out OK. Once any loose paint is removed from any of the countersunk holes on the toolbox, this product will fill and sand nicely. A new paint top coat and it should all look fine.

Getting this bit of work sorted out has also given me a chance to better understand how Canadian Marconi fabricated these boxes/cases back in 1944. There were definitely specific steps to be followed on the line. For example, all the countersunk holes had to be filled prior to any of the metal hardware being fitted to the exterior of the box, as some of the hardware overlaps these holes. I will post what I have figured out the line work was shortly.

This has also been an interesting exercise in clearing my head of all things ‘Sender’. I needed to step away from that part of the project to better understand what the issues with the Sender might, or might not be taking place.

Dave, I just finished a complete window resto on our 1897 dated house. Glazing putty and me (plus the guy at the Home Hardware and his glass cutting table) know each other very well. My first few attempts at re-glazing went very badly but now I can do a smooth 45 degree putty job as good as the best of them (if I do humbly say so myself...).

Most of the lower section of the content label that broke loose in the inside of the tool box lid survived as the three small pieces found in the bottom of the box when received. It is now time to glue them back in place.

I initially thought the original glue might have been mucilage but then realized that glue is always water soluble and the label would have been completely gone by now, had that been the glue used. Looking at some of the surviving glue, I now suspect Canadian Marconi used the same glue as they were using in their Cabinet Division.

I have decided to go with the Elmer’s Gel Glue for refitting the pieces of label. It is a water-based glue that stops being water soluble when cured. Being a gel it does not run and it has a nice working time so I can fiddle with tweezers for a bit to get the three pieces of paper properly placed before the glue sets up.
