as

>First, I heard from Ian Lomax.  He said, "Your friend is basically right, b=
ut

>He is right.  I am overly enthusiastic.  I always have been overly

en

ks
>it can do anything a real car can do.  By the way, Ian, are you one of the

>I really didn't mean to say that cutting 1/4 coil off a spring with 10 coil=
s
>would make it hard as a rock.  I meant that it would make it harder.  In a
>rock like way, maybe.  If, by rock, you mean Ted Nugent.  Nevermind.  Forge=
t
>that I said anything about rocks.

>Then, I heard from Graham in New Zealand.

>"There's a formula for the spring rate of a coil spring which indicates tha=
t
>if nothing else is altered, the rate increases as the inverse of the number
>of coils.  E.g. if you cut saw two coils off a 10-turn spring (and this is =
a
>fairly substantial cut!), your new rate is 25 percent above the old
>rate...... I wouldn't exactly say that that was going up like a rocket."
>
>Hmmmmm. It is going to be really hard to argue with cold, unemotional
>science.  I wonder though, if you had a spring with 10 coils and you cut it
>in two pieces, one with 6 coils and one with 4, would your two new springs =
be
>40% and 60% above the original spring rate?  Just wondering.

>David's friend (that's me) continued: "A spring that is nice and soft at fu=
ll
>length gets as hard as a rock if you cut 2 inches off."
>
>Please, don't any one read more into that sentence than I originally put
>there.
>
>Then, Graham said, "This seems contentious!  Two inches of length of the
>spring might be, what shall we say, a quarter of a coil at most?  If your
>original spring is say 5 turns, the new rate with 4.75 turns would be only
>about 5 percent higher, by my arithmetic. Can't really say this is "hard as=
 a

>
>Geeze, I hate when someone points out that I said something stupid. How wou=
ld
>it be if I change that to read, "A spring that is nice and soft at full

>
>Next from David's friend: "If you want to lower the height of the coil 1
>inch, like you said you wanted to do, you might have to cut 8 inches of
>spring off, depending on the diameter of the coil.  You get a vehicle that
>rides like a lumber wagon".
>
>>From Me:  No! No! I meant: "writhes like a lumbar waggin"!
>
>>From Graham: "More contention....!!!!  According to the spring rate formul=
a,
>if I understand it, the rate's affected by the number of coils, not the wir=
e
>length as such. So I go back to my example earlier, in which cutting say tw=
o
>coils off a 10-turn spring increased the rate only 25 percent....... not
>really lumber wagon territory?"
>
>There I go again, mauled by a marginal metaphor of my own miscalculated
>making.   It does occur to me to ask this question however,  "If you had tw=
o
>springs, each one made of the same material with the same diameter, and eac=
h
>one was the same overall height, say 10 inches, and each one had the same
>number of coils, say 5 or 6, but one had a winding diameter of 3 inches and
>the other had a winding diameter of 6 inches, would they have the same spri=
ng
>rate?"  This very question has stolen my sleep for years.  Just based on
>observation, it would seem that the one with less material in it, would,
>...well, ah....maybe, have a higher spring rate.
>
>Then, as if prompted with all of the wisdom acquired by a lover's evening
>argument in the cold, bright light of day, Graham said: "If your Alfa is
>getting old, then the original springs and shocks will have worn and weaken=
ed
>and will no longer be Anywhere Near the perfect match for each other which
>the designers intended........ chances are that minor mods such as a bit of

>Whew!  Graham is 100 percent correct in the end.  We can argue theory all d=
ay

at

>In my tired, exhausted minds eye I saw new suspension components on a car

>On the other hand, does the phrase "anal retentive" bring anything to mind?

>In reality, however, Graham spoke the truth.  He said, " we're not made of
