ok...i've got two c-record cranksets.....both in VERY good condition.
less than 100 miles i'd bet.
i've got three sets of taps......park 9/16ths X 20......eldi 9/16ths
X20.....and var 9/16ths X 20.....
i've got two sets of pedals....decent platforms from mks and a set of
shimano pd-m959s......
let me be very clear here and mention that the threads on the spindles
and the cranks are SPOTLESS. there isn't even a hit of grease or grime
or anything on or between the threads.....i'm meticulous when it comes
to cleaning things. wiping is for asses.
so.....i try to thread each pedal into the proper arm. i can turn the
mks and shimano spindles about three whole turns and then it gets
really tight. i'm not one to force things for fear of damaging the
threads.....so i back them out....i try threading them in from the
backside of each arm and they thread in like butter......so i figure
that the first few threads might be damaged....
so...and here's the weird part.......i take the three sets of taps
(each are about a year old but none has seen more than about 10
uses)......
the var first.....on each arm....i can't even get the tap to penetrate
the face of the crank arm.....can't even do that....and if i can't do
that.....i can't get a hold of some threads.....
BUT.....with the vars from the backside of each arm...i can get about
two whole turns....and then....it's like i'm using a tap that's tapered
cause the tap won't budge....again....i'm not forcing anything....
next the eldi.....same thing....can't even get them IN the hole to try
to catch some threads.....
BUT.....from the backside of the arm....same thing...i can get two
whole turns on each.....
last the park.....front the front i was able to get three whole turns
then a lot of friction.....
so i decided to tap the arms from the backside.....a bunch of
effortless turns and at the end...the tap meets some resistance but
passes right through pulling up only a fine bit of aluminum....the bits
were about 1/10th the size of a piece of glitter....really fine....
so i think it's odd that neither the var or the eldi could even get
started from the front...............BUT from the back....i couldn't
get more than two whole turns and then just a harsh hault after those
two whole turns.........
but just to be sure....i tried to pass the else set and the var set
through the front and back of the arms AFTER passing the park
through......
same thing.....i couldn't get EITHER the var or the eldi to get past
the face of the arm.....and from the back side.....not but two hole
turns and i coudl easily feel that the tap would start gouging up
chunks of aluminum from the arm........
so...i thought 9/16ths X 20 was 9/16ths X 20 no matter what tap was
used?
the taps weren't trashed or in poor condition.....neither were the
cranks or the spindles.......
anyone have any idea as to why the eldi and var wouldn't even allow me
more than two whole turns from the backside of the arms (even AFTER
passing the park taps through the arm) and none from the front?
pics will be posted tomorrow.......
