Additions to the Shimano 8-speed IG hub page

Spoking for large hubs, improved
The article on special spoking patterns for use with extra-large hubs (for example, electric bicycle hub motors) has been improved with patterns which avoid twisting the hub shell for two of the hub and rim combinations. The article includes all the information needed to use Damon Rinard’s Spocalc (also on the site) to calculate spoke lengths for these patterns.
Check spoke tension by ear when building a wheel
Check the level of spoke tension by ear — unless you are tone deaf, a musical pitch reference (pitch pipe, tuning fork, smartphone app etc.) is all you need to tell whether you have brought spokes up to the appropriate level of tension when building a wheel. It’s faster than using a tensiometer!
Spocalc revised
The page for Damon Rinard’s spoke calculator has been revised, with an updated list of online spoke calculators, several comments and links, and better formatting. Now also includes links to spoke-calculator apps for iOS and Android smartphones!
More hubs in cable-pull cribsheet

Shimano 4-speed hub gears
Expanded coverage of Shimano Nexus 4-speed hub gears — we now have rebuilding information, translated from manuals in German which are the only ones we could find online — complete instructions for both the freewheeling/Rollerbrake version and the coaster brake version. Thanks go to Patricia Morris for assistance with translation.

Shimano 8-speed Internal-Gear Hubs
Major revision to the page about Shimano 8-speed hubs:
— Added information on new hub models and fixed the many links which Shimano broke when it went to its new organization of technical Web pages.
— Linked to a number of documents Shimano abandoned. They’re available in the Internet Archive.
— Located other orphaned information where I could find it elsewhere on the Internet.
All in all, I’ve brought the information on each model of hub together in one place, to the degree possible with what I could find. Please let me know about errors and omissions.
