Flight crank question

<< < (4/5) > >>

jezza:
thanks guys your input is appreciated  :)

i have the spindle set up with the threaded side on the opposite side to the chainwheel, i thought as 1 piece cranks are that way i assumed 3 piece ones were the same

SaMAlex:
I always built the ones I had like you say: Chain ring on the right, lock nuts on the left.

As the arms just sit on the taper and stop way short of the bearings and lock nuts I cant see it making a diference what way the spindle is, as long as it fits.

Good luck with it.

Frosty:
Jezza,

I think the way you have installed them would have given you the most clearance, but it may be worth reversing before going down the new crank route!

jezza:
ive had a thought  ::)

im going to manufacture a square washer to fit inside the crank arm about  2-3mm should do the trick, the bolts are long enough to cope with this so fingers crossed, ill let you know

SaMAlex:
You could use "Ally taper shim". You know, the one that comes free with every can of coke. Wrap some of the can round the spindle in a cone and then crush it into a square with the instalation of the crank arm. It works when the square on an ally arm is opened out and might be easier than making a washer.
