wheelbuild advice

Howdy

Looking to build my first wheelset, as I want a specific disc hubs on specific rims, and I'd like to learn how to build and true wheels myself. Any advice regarding my choices and spoke lengths below would be appreciated!

Front, 28h:
HplusSon Archetype Rim
Shutter Precision PD8 dynamo hub

Rear, 32h:
HplusSon Archetype Rim
Novatec D772 hub

Using the Edd spoke calculator, it says I need (for 3cross):

Front:
Spoke length left 292.4 mm
Spoke length right 292.3 mm

Rear:
Spoke length left 288.2 mm
Spoke length right 288.9 mm

Obviously, you can't buy spokes in non-integer lengths, so would I be looking at buying 292mm for Front, and half 288mm, half 289mm for the rear?

Also, looking at DT Swiss Comp black spokes and DT Swiss black alu nipples, 12mm. Will be buying on payday in about a week, so I've got a week to read up on wheelbuilding before I buy the parts and tools!

Looks right to me.

Probably worth waiting until the rims arrive and measuring the ERD manually as manufacturers can be woefully wrong, although I always found H+S to be bang on.

Also, any reason why alu nipples? Brass ones resist corrosion better and the weight difference isn't worth mentioning.

3cross isnt always the strongest way to build a wheel.
I have a 24 spoke rear wheel which I originally built up 3cross because I was concerned about the low spoke count and wanted it to be fairly strong.
After taking it to shop a few times to get broken spokes replaced, the mechanic suggested rebuilding it 2cross because it means the spokes meet the rim at less of an angle. Had a lot less broken spokes after that.
Only really a problem on low spoke count wheels, maybe consider 2cross for your 28 spoke front?

I was looking on the Rose site and the Alu nipples have a substantially higher review rating than brass. That, and the Sapim website says that modern anodised alu nipples are just as resistant to corrosion, and are actually stronger than brass. Is that all just sales-talk?

Sounds like rubbish to me. Aluminium ones will seize up almost immediately and you won't shift them. Use brass and grease each one well.

Also, they look like standard double-butted stainless spokes. Have a look at the ones from Cyclebasket which come with nipples and should be a lot cheaper. I've used these on lots of wheels now and they are exceptional value and I've not managed to break any yet: http://www.cyclebasket.com/m9b0s453p0/Components_/Spokes_-_Stainless_Steel_BLACK_Double_Butted_

3-cross with 28H should be fine, but you can also use 2-cross on a front wheel.

They only come in 2mm Even increments from that site, so if the calc says I need:

Rear:
Spoke length left 288.2 mm
Spoke length right 288.9 mm

..then should I be getting half 288 and half 290 for the rear? Will the extra 1mm cause any issues?

*edit*

read up a bit more, and people recommend rounding down. I need to do some more reading!
