middleburn question

[JoelO]

not for me, for a friend:

Does anyone here know what the dimensions of a square taper spindle are? want to get a set of these, but not sure what ill need to machine my powerbite spindle down to, or what size spindle ill need to get made up in order to fit them in a spanish bb configuration.

if anyone has an answer or could point me in the right direction that'd be rad.

Edit: just realised it's not even middleburn specific, just dimensions for a square taper spindl.

it's quite an involved machining process. I can't find any dimensions. I have, however, an immaculate shimano dura-ace spindle I can loan to a machinist for measuring. It has had cranks installed once but never really used.

Be aware that the square taper spindle you're referring to is part of the JIS standard, NOT the ISO standard which would be available for download from www.iso.ch. ISO bottom bracket spindles are for campagnolo, miche and gipiemme cranksets.

I'm assuming you mean me joel, so yeah, gimme gimme gimme, cause i am kind of interested in knowing a little more about this one myself...

btw, how is the seatpost going?

seatpost is perfect. I scratched it a little in my "stand" but that's OK, I'll take out the scratches. I owe you a large beer for that one.

I'll clean up the spindle and get it to you...sometime.
