                        by Peter Ross

Meeting of John and Clive

John's curiosity finally got the better of him, and he stopped on his
way back from the swimming pool and introduced himself.  He and Clive
immediately hit it off, and they became good friends.  With his
connection with Lotus it is not surprising that the conversation soon
turned to what the Lotus people were doing, their plans for the Mark VI
with proper space frame, and John convinced Clive that he should get
Colin to design him a car.

John had a chat with Colin, who was very interested in the idea of
getting someone to finance the building of his first single seater, and
told John that if he could get the order, he (Colin) would give him a
job at Lotus, where he would be responsible for making it.  This would
be quite a big step for John who had a steady job with Poplar Council,
but he got the order from Clive and gave in his notice to Poplar,
starting work at Lotus early in 1952. according to John, Clive paid
Lotus Engineering 250 pounds sterling. Colin must have designed the car
during the winter of 1951/52, soon after completing the design of the
Mark VI which they finished building  in June 1952.  As the next
available number was Seven, the car was given the name Lotus Mark VII.

The new Lotus Engineering Company

The early part of 1952 was a busy time for the new Lotus Engineering
Company (not Limited in those days) which came into existence on 1st
January .  They had just completed the move from the Allen brothers'
home at Vallance Road, Muswell Hill.  This had involved laying concrete
on the floor of the old stables which had been used by Colin's father as
a store room for empty bottles.  This coincided with a some very cold
weather, and fearing that the concrete would freeze before setting they
had to fill the place with oil stoves.  There was no electric light to
start with, and they installed an electric generator and 24 volt bulbs
for lighting.

Colin and Nigel Allen would continue their day jobs - Colin at British
Aluminium in St James Square near Piccadilly in London, and Nigel as a
dental student.  Michael was initially the only full time employee, with
Mike Madden joining soon afterwards from Laystall Engineering, and John
Teychenne (as already mentioned) from Poplar Council.  They were kept
very busy with a flood of orders from customers wanting to race in the
750 Formula, Austin Seven engine overhaul and tuning, chassis
modification, hydraulic brake conversions etc.

Their most immediate job was to complete the Lotus Mark IV trials car
for Mike Lawson, and this was delivered in February or March in time to
be entered for its first trial on about 16th March.  The team were
itching to get on with the Lotus Mark VI, but cash flow required that no
customer could be turned away.

So in the early part of 1952 the Allen brothers and Colin were working
hard on the new Mark VI, in what one might call their spare time, whilst
Michael, Johnny and Mike were doing small jobs for customers and Johnny
was trying to find time to make the Mark VII.

Lotus VII specification

The Clairmonte order was for a rolling chassis with body, but the Riley
engine and gearbox was to be supplied by Clive Clairmonte, as well as
the Halibrand Final Drive unit.  The latter was bought from the USA (a
difficult undertaking at a time when dollars were virtually unobtainable
in the UK) and allowed a low position for the prop shaft.  The step up
gears at the back of this unit brought the drive line up to the centre
line of the crown wheel, and the transfer gears could be quickly altered
to change the axle ratio.  Clairmonte supplied a slave engine block to
allow the engine mountings to be correctly positioned, whilst continuing
to race his "hot" engine in the Riley..

Colin was determined that his first single seater would have a really up
to date specification as can be seen from the list of features shown at
the start of Part 1.  The space frame used 1-5/8"x20g tubes for the main
parts, and 1" dia for the others.  The front suspension featured coil
springs within dampers as on the Mark VI, and the lower wishbone was
made from streamlined section tubing.  At the rear the de Dion tube was
located by twin trailing arms and laterally by a roller on the tube
sliding within a vertical channel as he would later use on the Mk VIII.
Front brakes were 11" diameter with Alfin drums, whereas at the rear
standard 11 inch brakes with cast iron drums would suffice.

Because of the radically new front suspension (seen previously only on a
Maserati Grand Prix car), this was the first part to be built.

Johnny Teychenne recalls: "What actually happened was that when I
applied to get the welding bottles, they very kindly sent a
representative and he gave me some welding tests - I was fitting the
equipment up for the first time you see, I had NEVER used it.  And he
gave me welding lessons.  And he came back the following week and he
said "I don't need to teach you anything - you're a natural welder".

My memories of that wishbone!  That was the first bit of welding I ever
did for Lotus - edge welding of the upper wishbone on the Mark VII."

The chassis frame slowly took shape, but after about three months the
little Lotus company began to run out of money, and John and Mike had to
be laid off.  John got a full time job with Arnott's, the supercharger
people, who were starting to make 500cc racing cars, but he would come
over to Lotus in the evenings to carry on with the Mark VII.
