quick question guys

Hey guys, I just have a question, Im lacing up a wheel for the first time and the guy at the shop said that the disc side of the hub should have shorter spokes. It made sence but now that the rim is all laced up th hub is REALLY far off to the side and it can't be fixed with truing, I wanted to know should the short spokes be off to the non disc side or is it a mistake I could have made.

i think it is a mistake that you made it depends how much shorter the dist side spokes are. I was just learning this for myself today.

what are you asking here?

have you actually tensioned the wheel and checked it with a dishing tool?

yes, the short spokes go on the disc side...

Is it a front or rear wheel? On a front wheel, the disc side spokes will be about 2mm shorter. On a rear wheel the disc side MAY be a bit longer depending on the the hub/bike.
Some hub manufactures compensate for this by making the flange on the disc side of the front hub larger so all the spokes will be the same length. The only way to do this right is to measure everything and use a spoke calculator. You can download a spoke calc on the web and check to see if you're way off.

What hub/rim are you building up?

On my XT hub, the shorter spokes go on the drive side so that the wheel is dished properly.

NORCAL is the hizzle
On a rear disc wheel, if anything the drive-side spokes will be a little shorter (the cassette takes up a bunch of space, so the drive-side hub flange is closer to the center, so the distance from flange to rim is shorter). For a front, yeah the disc side will often be a little shorter.

Sounds like you need a dishing tool. It's a guage that tells you whether the hub is centered.
 
Actually I got an old rear wheel and took it apart and laced it again and I think i have the idea now I think my issue last time was right when I started building the rim I kept putting one trailing spoke in the wrong place and it screwed up the build every time but thanx for the help

While each side is laced separately, you have to align each side correctly.

My friend laced one side, and then he incorrectly put the other side one spoke hole over. When putting the slightest tension, the wheel pulled too much to one side...

That's why the first two spokes I lace is the "key spoke", then the spoke on the side of the hub. If you do those two correctly, the rest of wheel falls into place.
