spoke length for different patterns?

Spoke calculators seem to cater for 3 cross, 2 cross and conventional
patterns but not for crowsfoot, 2 leading, 2 trailing, etc.

Even in crowsfoot and 2-leading-2-trailing and patterns like that, any
given spoke is cross-n, where n can be 0 for radial. Look at it in a
different way: if you draw a spoke directly from a hub in the hole to one
of the holes in the rim that is closest by, you have radial or cross 0.
That establishes the relative postion of the hub and the rim. Now, if you
put the spoke one spoke hole further along (be it leading or trailing
direction) you have a cross-1 spoke. And so on. So essentially, a cross 3
spoke is 3 holes over from where it'd end if it were radial.

The only exception is when you get into hubs and rims with different
amounts of numbers (typically hubs with more spoke holes than you have in
the rim) -- but for those you just need to get out the old pen, pencil,
and trigonometric calculator.

Hi Jasper,

I hadn't thought of it like that. Thanks.

I was curious how everyone else works it out.
I suppose it helps to have some spare spokes lying around.
I will try experimenting once I get my spokes. I have none at the
moment!

Even if my first wheels are standard cross 3 I hope I will be proud of
them. I can't wait to get started!

Thanks again!
Taka

Well, most of us that build for a living, don't work out anything like
crow's foot or anything else except 2 cross, 3 cross and 4 cross. The
other stuff, altho interesting, does nuthin to make a wheel better.

The key words here are 'prettier' and 'more interesting'.

Yep, I know. I have built a crows foot with 24h and 32h, it was
interesting. Then tied and soldered the three spokes together, ala some
of the time trial wheels in Stars and Watercarriers.
