Wheel Rims and rebuilds
« on: April 16, 2019, 08:18:59 AM »
My rims are no good  :'(
This hopefully links to my post and picture in the WR200 section: http://www.yamahait.com.au/forum/index.php?action=dlattach;topic=24366.0;attach=10583;ts=1555365837;image
I've not rebuilt a wheel before, but YouTube should help me.  I'm thinking to assemble everything and then hand it over to an expert to tension and true everything.

But what I'm really here to ask is for any advice on getting the nipples undone without destroying the spokes so they can be re-used.

Thanks in advance  :)

I have no patience.
I do have a disc cutter though  ;D
Go soothingly on the grease mud, as there lurks the skid demon.

GRIP AND RIP CRAIG AND CHRISSO!!!

Plan 'A'
50/50 mix atf and acetone, a few of drops each end of the spoke nuts every couple hours (or once every beer if in a hurry) then leave over night (or until hang over gone if you were in a hurry). Then heat nipples for about 20-30 secs with small needle point butane/propane gas gun. Then go to plan 'B' 😋
Haha, no before plan B give em a sharp twist (impact driver on nipple end if the slot is clean) and test your luck. The trouble I reckon is that unless you get them all off cleanly you may as well have just cut them 😞
What goes up must come down, unless you broke a 'rod 😞

Hmmm  :-\ what nipples do I need?
No p/n for individual nipple as far as I can see, just the spoke set.
They seem to be something not metric.
Spoke diameter is 4mm.  Nipple diameter 7.1mm (though that doesn't really dictate the size of the hole drilled in it)
Std. metric would be 0.7mm pitch = approx 36 tpi, so it's not that.
Picture shows vernier jaw set to 10mm, and approx 13 threads.  Could be 12.6 threads in 10mm = 32 tpi = 0.03125 = 1/32" ??

Anyone happen to know or can help point me in the right direction please?

Looking for the 'Like' button!

Also,  imperial sized wheels, chain, handle bars; and of all things headrace bearings......Yes, your latest sports bike might use cup and cones with imperial sized balls!

Cheers,
