Eventually the Rochford works closed and we all moved back to Southend, Mr Taylor asked me to become the estimator for the Electronics side (I can't remember what happened to Mr Tucker) and production was moved to the ground floor of what had been the new D&E building.
By this time Pye had taken over and Radio and T/V production had almost stopped. There were very few new units coming from the labs and it was clear to me things could not go on like this for much longer. I had always wanted to live in a more rural position and about this time the opportunity arose to do just that, so I left in about 1974 and moved to Suffolk.
Part 2 An Estimators estimation of estimates
To paraphrase Messrs G & S "When there are estimating duties to be done an estimators lot is not a happy one". Even Mr Barnham said he could please all the people some of the time….if only…
As the name of the department implies our function was to tell the management how the prices of various units being developed changed as development progressed until the product was fully engineered and all drawings and stock lists were available when we would do a last "estimate" which would really be a costing as all the correct information and prices would be available.
Most units would be estimated at least three times, firstly when it was not much more than a twinkle in the engineer's eye when "Guestimate" would be a more appropriate term, at this time we were totally dependant on the goodwill and cooperation of the engineer concerned. Luckily this was always forthcoming and if I was lucky they would let me take the unit away to work on.
The mechanics of producing an estimate are, in theory, quite simple.
- list all bought items and put the cost against each item and total.
- list all internally manufactured items and all assembly items estimate a time for each operation, multiply this time by the rate for the department, add on the overheads, put the two together add to the material cost, et voila one Factory Standard Price, hereinafter referred to as the FSP. Any tooling charges were usually shown separately.
The assembly or manufacturing times for in house items were calculated using "Synthetics" these are really statistics and we all know what they are!! We were not allowed to use a stopwatch for reasons I never really discovered, so we used synthetics, there must be an enormous volume somewhere covering every human activity from Angling to Zoanthropy. A Relaxation factor is built in known as tea and pee. Every operation is broken down into its smallest elements, for example: - to prepare a 6 inch piece of PVC insulated copper wire, it sounds a bit like Mrs Beaton. First get your wire, measure the wire, strip both ends, twist both ends then solder both ends. All these elements are added together to get the final basic time, this basic time is then modified depending how many are being made. It is based on a much modified Bedeaux (I think that is how it is spelt). But when the new bloods arrived in the form of Barry Matthews and his colleagues, this was considered very old fashioned and out of date, but that was how the management wanted it done so that was how we did it.
If the unit to be estimated came under Avionics I would go and see Bill Graville, if it was not one of his units he would tell me where to go (In the nicest possible way of course). The E190 and the E390 weather radar came from Bill while the high voltage units being developed came under Mike Rose.
If it was an electronic unit I would go to Tim Davis who would pass me on to the correct engineer.
To take a specific example, Safe load indicators. These came under Bob Hubbard so I would go and worry him for a while and get as much information as possible, if it was very early in the development stage I would add on what I grandly called a contingency but what my "friend" Bob would call a fiddle factor. This would be done two or three times before the unit was fully engineered.
One of the Engineers, I forget which came up with a capacitor made by Mullard which is unusual. I wrote to them asking for information and prices. Back came a letter saying sorry cannot help this is not of our manufacture. I borrowed the catalogue and had the page copied, this I sent to Mullard with a note on the bottom "get out of this" a few days later a letter arrived starting with "having recovered from the embarrassment of not recognising our own products" and giving me the information I required.
The worst estimate I ever put out concerned a small modification to (I think) a GPO chassis. It consisted of adding about 6 new components to a small aluminium chassis; there were only about 10 of them, one of which was an electrolytic capacitor and a clip to retain it.
We sat a young lady down in empty office in the Rochford Factory gave her a hand drill and said, drill a hole there and put a nut and bolt to hold it,…. I had already told her she had two minutes per chassis to drill the hole secure the clip with a bolt, shake proof washer and nut…
After about 20 minutes she came into the office, 'hello said I finished?' She burst into tears and said 'I can't get the drill to work', the drill looked alright to me but we gave her another drill and left her, she came back again still in tears because the drill would not work. This time I went with her and tried the drill myself, after about 6 turns it went through, 'there you are, you try'. She sat down and started turning, after a few turns I realised she was left handed and was turning the drill the wrong way, it ended up with me drilling the holes while she put the nut and bolt in. So a job that should have taken about 20 minutes took about 2 hours. Not one of my better efforts.
In the office next to me there was a group of people under a Geoff Upton who took our figures, checked them and produced FSP's for all the sub assemblies in any given unit. This was a great help at times because if the engineer said it is like DP12345 I could look up the price complete and use it.
Another disaster, not of my making this time, occurred at the Dynatron factory. they were asked to produce 12 cable-forms each about 6ft long, and to deliver them three per month. If they had made them all at once the problem would not have arisen but they chose to make them three each month. Due to the small quantity it was not worth expensive jigs so they bought a long tape measure and stapled it to the bench for the girls to measure against.
The first three were made and dispatched and accepted as OK, next month the next three were returned as being too short. They were checked against the measure and found to be OK so were sent back only to be returned again as being too short, after much scratching of heads the tape measure was checked against a steel rule and found to be short. It turned out each week the girls washed the benches down and the tape measure had shrunk!
The GPO, by law had to put any contract out to tender. But what they did is ask Siemens or TMC to quote for 200,000 and ask us to quote for 500, One such contract was for 'contactors', which consisted of dozens of Phosphor Bronze contacts, as it was not economic to tool up for such a small quantity I wrote to TMC asking the price. Back came a price with a catalogue in which was the price of the finished article less than the price they quoted us for the contacts alone, you can't win.
Some of the units I worked on never saw the light of day, there was the E214 developed by Eric Fielder this was a computerised table for a vertical mill or the Fail Safe unit for a Guillotine developed by Bernard Hutchins, or perhaps they did after I left!
On the whole I really enjoyed my years as estimator for Electronics I was not tied to a desk all day and could come and go freely into the labs and drawing office.
I will end with two coincidences, we have lived in Suffolk for 30 years and in our present home for 5 years, the neighbour one side worked for Ekco Ensign and the other an elderly gentleman by the name of Swan told me his father worked for Mr Cole when he was making battery elimininating circuits in a shed in the back garden.
I also met and made some good friends and via the wonders of the Internet have made contact with one or two ex-employees after a break of 30 odd years.
