1960‘s Secondary School Education

Let’s go back to a time when the UK had Factories to produce products for sale around the world
Each part sold supported our Nations GDP
What did these industries need? Workers  

So the UK School Education system produced them in their tens of thousands
Secondary Schools supplied the workers,
Technical Schools supplied engineers and designers
While Grammar schools supplied the academics, or so they thought
 

Those factories were mainly ‘Tin bashing’ a colloquial name meaning making things with metal
Which could be Ferrous or non ferrous, 

Such as Aluminium and Brass Castings for the automotive industry
Press work making formed parts for Auto or Domestic products
Not forgetting high volume Capstan lathe parts and the Plastic moulding trades

While other Factories made products from Wood,
Furniture for homes and schools, with windows, doors & frames for them all  


 The curriculum for Secondary schools was the same over the UK

Lads were educated in Maths, Physics, Chemistry, Metal work, Wood work, Technical Drawing, and English
Back then Schools had segregated lessons,  Boys had different lessons to the Girls,

 

I start with my own journey through life with the things I made that survived the years since  

 

 

Tea or Caddy Spoon  

We start with my first ever metal work part made at school, I was 11 at the time 

Back then this was a normal kitchen item,  a Caddy spoon
There were no tea bags back then,  tea was sold lose 



  My actual Tea Spoon

Made from 1/16” or 0.064” as it was then, now 1.6 mm Copper sheet
Marked out using a scriber, and dividers, odd leg callipers, then drilled and hand filed to size
The spoon was then formed hammering in a wooden block with frequent heating with a gas torch to keep the copper soft , when done the handle was hand planished  and finally polished  

 

 Ash Tray

The Next item was an Ash tray, back then almost everyone smoked
Men,  women, teachers & doctors, you name it they smoked
This led on from the caddy Spoon


My Ash tray

Made from 1/16” or 0.064” as it was then, now 1.6 mm Copper sheet
Cut from a sheet into a big blank then hand marked out with a scribe
Using the same method as the spoon above the copper blank was fitted in a wooden block with a hollowed recess
 The copper was then hammered into the dished shape again with frequent heating with a gas torch to keep the copper soft
Once filed and levelled it was planished and finally polished and a green baize cloth circle glued on the underside


 
Toasting Fork

Back in the days of Coal Fires it was customary to toast Bread by holding it close to the fire
But not any bread, it had to be from a “cut loaf” one where you cut of a 1” thick slice
Stabbed it with the toasting fork and held it close to the fire to brown

My Toasting Fork

This is made of 1/16” or 1.6mm Brass with a 5/16” or 7.9 mm round brass shaft
Hand cut and filed then soft soldered together and finally hand polished

 

 

Coal fire Poker

No self respecting coal fire can go without a poker to move around the coals to keep
The fire going and settle the ash into the pan 

 My Coal fire Poker

Likewise this used the same decorative brass end finial as the Toaster,
With a Square mild steel shaft and twist for a handle which was made by heating
The steel in a Blacksmiths forge and twisting in a Swage block
To finish the iron rod was straightened on an anvil   

 

Moveable Spanner

This was a pleasure to make, and was used extensively on my old Vindec bicycle

 My Moveable Spanner

There are 4 part to this functional tool, the Main backbone and fixed jaw, the moving jaw,
The adjustment nut and a sheet steel frame, all held together with countersunk steel rivets.
The task involved Knurling the bar then drilling and tapping the nut and parting off to size
While the Moving jaw was turned down to size then threaded with a die
While both jaws were case hardened



 

Screw Driver

This was in use right up to the early 2000's when I retired it   

 My Screw Driver
The manufacture of this involved an number of manufacturing processes
Starting  with a rod of ¼”,  0.250 “ ,  6.4 mm Silver steel which was heated in the forge and hammered to a tongue at both ends
One end was hand ground to produce the Screw driver blade then the whole bar cleaned with emery cloth
The Screw driver blade was fitted inside a two part moulding die
Which was preheated on the Gas torch,  while a pot of broken up aluminium parts was melted in the forge

When the slag was cleared from the pot the Aluminium was poured into the Mould
and allowed to cool , the die disassembled and the screw driver removed and cleaned up
It went in the lathe were the handle was sized up to diameter and length then knurled
The final task was to harden and temper the blade



G Clamp

Not used much through the years, it did help during my welding

My G Clamp
This was made from 5/8 x ¼ Mild steel bar
With a ½” round bar turned down to 3/8”  for dieing to 3/8 Whit Tread
with a little handmade cup washer for the end  

The Bar was measured & marked then heated & bent then hand filed to size

 


Stud remover, currently lost  will update when found


The next item was not part of the School curriculum
Around 1969 Dads garden shed had been broken in and some tools stolen
I mentioned this to my metal work teacher
Who a week or so later called me over and gave me some Drawings of an Asp and Staple 
 
 

After 47 years service it was finally removed and retired  

 

Wood Work items to be continued     

 

 


My kindest and most sincere regards and respect go to
Joe Lyons,  Metal Work
Horace Tickle, Wood Work

With a special thanks to
William (Bill) Black, Physics
Jeff Cane, Chemistry

 

Not forgetting Mr Patterson Head Master

Who trusted me enough to go on an Evening institute Electronic Course,    

When I was just 14 years old
With the proviso I paid the £1 10s myself

I think that 30 bob ( £1.50 ) was one of my better investments

Waddington’s Future Scientist Flash Photography

 Waddington’s Future Scientist Flash Photography

Once more we’re time travelling back to the 1960’s, this time to another Christmas Present long gone and replaced from a well known on line auction site in quite good condition

Simple black and white photography in the form of a educational toy

 


CAMERA 

 

The Kit contained the following

1, A Diana 120 roll film Camera, with flash attachment for Flash Bulbs

I believe they did a cheaper set with NO flash

 

2, 1 x roll of 120 Film

3, 1 x Small thermometer

4, 3 x packets of Chemical A , which I believe was ILFORD ID-11 Developer

5, 3 x Packets of Chemical B,  Sodium Thiosulphate Pentahydrate

Better known as “Hypo” fixer solution   

 

6, 2 x Small Packets marked C ,  Photographic paper

7, 2 x Large Chemical trays and one small Chemical tray for Developer Wash and Fix

8, 1 x Small Plastic Exposure frame  

9,  2 large Wooden Tongs , for holding the film or paper whilst developing  

10, 2 x small Plastic clips

11, 1 x small 15W safety lamp

12, Instruction leaflet, (Lost)                                                                                                                                                                                                                  

 
 

Focus 

The Focus is continuously variable with 3 setting points 4ft to 6ft -  6ft to 12 ft  &  12 ft- inf



 

Shutter has two settings B and I ,

The “B” setting holds the Shutter open for Flash bulb or low light

The  “I” setting opens the shutter for around 1/60 second 

 

 

 

Iris – F stop

  

A basic but function adjustment with three Settings

Sunny – Sun & Cloud - Cloudy

and it does work quite well

 

Loading the Camera

Obviously a dark room would be best or Film loading bag,

I used to load my Camera under the bed sheets with the room curtains closed 

 

 Flash 

 

The Flash uses standard PF style bulbs which are still available

It uses 2 pins to plug into the Camera 

While the Gun hides the batteries inside    

The little white plastic button ejects the spent Flash bulb

 Comments

It worked well, I still have pictures to this day that have not faded with time

Timing and Temperature were the key  

 

N.B. this is now part of my collection
