Wheel lacing
Hi,
Here is my problem. I am used to do standard wheel lacing (3 crossing) for 36 spokes. However, I have just received a new rear hub and my supplier tells me that it's going to take at least ten to fifteen days to get the spokes I would need (183 mm)
So I decided to play with the lacing and see if I could test another pattern in the meantime and use my existing spokes (189 mm - just in the midle between the 3 and the 4 crossing).
I have found references to "three and a half" crossing but I can't seem to find the lacing plan that goes with it. I don't even know if it's real or not.
Does anyone has any information on such a lacing (a close pic or drawing would be perfect)?
Thanks in advance for your answers.

No, but I don't think that'll help; it sounds like you'd need three different lengths of spoke for such a lacing, and I don't think you'd be happy with it. 183mm spokes aren't hard to find; I propose you check around some more or wait.

One bug-ugly (possible) fix is to get a handful of M5 thread nuts and use as washers/spacers. Push the nipple through the nut before putting the nipple through the rim and threading it onto the spoke.

I have found pop-rivet backup washers of aluminum,
that will have a hole in them just right ID for spoke nipples.
then you will want long spoke nipples.
but as I read it, you just, are too impatient to
wait for special order cycle of shipping, get the right length of spokes..
A Shop with a spoke tread rolling machine can roll more thread,& cut spokes shorter.

Crown Bolt Washers SAE #8 Brass = 15g/14g nipples
Crown Bolt Washers SAE #8 Zinc/Steel = 13g/12g nipples
Those are what I use when I need washers...

3.5x?
I guess it could be 2x + 4x
It's not a normal pattern, but it works. The leading spokes are laced with 2x length and the trailing are laced with 4x. There's not a lot of benefit to this type of lacing. If anything, I guess the trailing spokes, being more tangent, fair better against torque, but that's about it.
There is also crow's foot lacing, but it still requires 3x length spokes, just 1/3 less
Yet another option is 3 leading, 3 trailing, but this still requires 3x length spokes all around.
