Wheelbuilding: "Weave Rule" (w pics)
Wheelbuilding: "Weave Rule"
This is my first time building a 2 cross wheel. When I've built 3 cross wheels in the past I've observed the "weave rule", which essentially states - if a spoke head faces towards the center of the hub, it weaves under the final cross. This is exactly what I did, and the pics tell the results. I don't like all the bending and "conflict" between the spokes. There is essentially no tension on the spokes at this time. Whether it's right or wrong, I believe the spokes will straighten when I add tension. I'm concerned.
Any help would be appreciated.

Yes, the spokes will straighten as you increase the tension. But I'm curious: why did you choose to built this wheel 2-cross?

I bought a kit with everything pre-measured. There were no instructions, no pics to reference. The set is as radial pattern front and 2X in the rear. I wish the kit included more info but is what it is.

FBinNY will probably jump in. The theory behind interlacing the spokes is, when a spoke is stressed, part of that stress is transferred to it's partner spoke. Since spokes almost always fail at the elbow rather than where they cross, I'd think that interlacing would produce a somewhat longer lasting wheel.

Still the stresses at the hub shell hole are greater , the closer the spoke is to Radial , as the metal to the edge of the hub flange is Less..
But still my Rohloff Hub was laced as Hub factory specified : 2 Cross in the 26" wheel 1 cross in the 20".
(but thats 32 not 28)

Isn't 2-cross the most logical for 28 spokes? I'd think you'd go beyond tangent with 3-cross, but I might be wrong.

Before you tension it up, make sure your valve hole is between parallel spokes.
Yes, you are doing OK. That's what a wheel is going to look like before you start putting on the tension.
And yes, the spokes should be crossed at the last intersection so that they touch.
Divide by 9 and throw away any decimal part. That's the MAX number of crosses you can use.

Ah, nice! So 3x would be darned near perfect for these after all.

Yea, It's Now like 3 cross in a 36 hole hub, just not as many spokes sharing the load..
My Burly "flatbed" 20" trailer wheels are 28 spoke 3 cross [in a 406 rim]

Thanks for sparing my fingers.
