It's my first time trying to re-lace a wheel, and I'm stuck, by something I imagine is ridiculously simple.
The bike is a 1975 CB550K, stock hub & stock 19" rim. New spokes & nipples to suit from David Silvers, which are identical to the old ones.
So I lace up the first side of inners starting at the valve stem hole - every second hole on the hub going to every fourth hole on the rim. The nipples are only just threaded on. I make sure the rim dimples are orientated the correct way, and once laced, the hub is turned so that angle of the spoke is correct.
With everything exactly the same, flip the wheel. I count 7 holes around from the opposite side spoke at the valve stem (as explained here
https://bikebrewers.com/lace-motorcycle-wheel/) The explanation here all seems to match the photos I took before disassembling.
With the nipples loosely on, there is plenty of movement. I can get the first one, maybe two spokes in, but they have to be coaxed around the already fitted spokes. The more spokes fitted, the harder it becomes, and the spokes would need bending around the others to fit. Hopefully the pictures below will illustrate what I mean.
So what question is, what is my simpletons brain missing here?
