Top Gear<\/strong>\u2019s Africa adventure on the telly and the
pistons\/crankshaft assembly in the cylinder block, and the pistons made
satisfying up-down movements when you turned the crankshaft. The
instructions said that you needed sanding paper to get the edges of the
plastic smooth, but as we lacked sandpaper we made do with nail files,
which seemed to do the trick. The whole thing turned so smoothly that we
didn\u2019t even need the vegetable oil to make it work.<\/p>\n
\u201cThis would be even better if it was the right size,\u201d I said
as the plastic innards were slowly swallowed up inside the
model.<\/p>\n
\u201cThat would be much more satisfying,\u201d Colleague X agreed,
trying to get the tiny screw to stay perched atop the tiny
screwdriver, and slot the entire thing into the tiny hole on the side
of the crankcase. \u201cThis feels more like keyhole
surgery.\u201d<\/p>\n
\u201cWhich is also important.\u201d<\/p>\n
\u201cYes. But not the sort of thing I had in mind when I bought the
six-pack.\u201d<\/p>\n
I, too, was getting a little restless. Earlier that week I had opened
my planner to try to book a last-minute meeting with a senior
colleague. He, peering over my shoulder, wanted to know what
\u201cEngine Build\u201d was referring to, and why it had so many
exclamation marks. I attempted to explain.<\/p>\n
\u201cHmmm,\u201d he said, frowning. \u201cYes, interesting. But an
engine\u2019s a big commitment. Did you think about starting with
something a little smaller?\u201d<\/p>\n
A motorcycle? Sure. Ultimately, though, I\u2019d decided on the
engine, because I was learning to drive a car, not a bike.<\/p>\n
\u201cNo, not a motorcycle,\u201d he said, just as thoughtfully.
\u201cSomething smaller. A lawnmower, maybe, or a
hairdryer.\u201d<\/p>\n
I very pointedly did NOT stab him with his own pen, but instead said
that we were doing a model version first.<\/p>\n
\u201cYes,\u201d he said. \u201cI think that\u2019s probably for the
best.\u201d<\/p>\n
Anyway, other than patience and tact when faced with senior people and
their hairdryer suggestions, what did I learn from doing this little
side-project?<\/p>\n
Firstly, it\u2019s bloody cool. There\u2019s now a little engine model
on a shelf in my living room, and if you press the little button it
lights up and makes happy engine noises.<\/p>\n
Secondly, the instructions may well be wrong. Try the different bits
together until they fit. This will probably be more useful that
memorising engine layouts.<\/p>\n
Thirdly, the reviews and advertising for this product piss me off
something chronic. \u201cIdeal
for a dad and son project<\/a>,\u201d one proclaims. Well, yes, it is,
but it\u2019s also ideal for a dad-and-daughter and mum-and-son
project. Or mum-and-daughter. It\u2019s basically model assembly, and
doing this with a kid (without taking over and finishing it off
yourself) would probably take an afternoon.<\/p>\n
Fourthly, the rocker arm assembly fits on top of the valves and the
camshaft, and there\u2019s only one correct way of lining up all the
cams on the camshaft. There is no obvious way of knowing what that way
is without having them labelled in alphabetical order. (This may
require a textbook. Or a mechanic.)<\/p>\n
Finally, although doing the plastic model was fun, it is limited in
several major areas. It is extremely simplified, for one thing. The
water-pump is two bits of plastic moulded and snapped together. The
\u2018sparkplugs\u2019 are tiny Christmas tree lights that light up
according to the position of the crankshaft (so the position does have
to be correct, and the wiring is a bit tricky, but it\u2019s not
actually how a spark plug works). The dipstick is a completely
pointless clip-on piece of plastic that looks like a Barbie accessory,
and I still have no idea what it does (although presumably you dip it
in things).<\/p>\n
