alright, so I'm not sure if my just describing this is going to even give you guys a chance to help, but I have to try.
So I am building this wheel (shimano E-type coaster brake and sun AT18), I used a spoke length calculator program down at the shop and got my correct length to be 295 rounded up(from 294.9). So I have off set eyelets, so it's a lot easier to see which spoke goes where. 36 hole,3-cross fyi.
(assuming looking through the axle at the side of the wheel)
I start with the first spoke through the bottom flange and go to the first eyelet to the right of the valve stem hole. Then I count four holes to the right on the rim and put the next spoke, which, on the hub, is in the hole two down(same direction relative to the spoke placement in the rim). So on the hub I have a spoke ever other hole and on the rim every fourth hole.
Then I go to the top flange and select the next hole to the right of the first spoke hole just used in the bottom flange(because the two sides are offset a bit). I then take that spoke and go to the hole just to the right of the first spoke. So I have two spokes in the rim right next to each other. Then I laced it up just like previously stated for the bottom flange, only this time for the top. every other hole, and every fourth hole. So I now have groups of two spokes in the rim with two holes in between.
I then twist the hub to the right(towards the direction that has the spokes closest to the valve hole).
Then I proceed to drop spokes into the bottom flange. This time I go the opposite direction, crossing once at the hub, then again just a few mm away from the hub then under the final spoke, a few inches from the hub flange and put it into the first hole open closest to the last spoke crossed. I do that for the whole side.
So now I have the entire bottom flange "done" ever hole is filled.
BUT WAIT, somethings up. The two spokes(the initial spokes from each side) are now sticking like half an inch awa from the hub everywhere. The set of spokes that I put in(the ones that did the crossing) fit fine, but if you look at the wheel, Two spokes stick out of ever set of three(because I never finished with the other flange).
I don't know what to do. I was following some old book to the T. It even said that there were two types of rims, more common ones which have the high eyelet as the second eyelet away from the valve hole and less common which have the high eyelet right next, on the right side, to the valve hole. Now I know it's a "more common" rim because I have just laced a "less common" and I can see the difference. I triple checked my spoke length. I relaced twice. I just don't know. So now I feel a bit better, as this has ruined my friday. thanks for whatever help you can give, and I again apologize for the lack of images.
