Would it work ok to use a 28 hole rim and just use every second hole for the NDS spokes?

Nah, the uneven spoke tension is due to having 14 on one side and only 7 on the other. The extra (unused) holes won't really affect the spoke tension.

Lace 7 NDS radial, one hole either side would be the 14 DS crossing spokes. Leave the hole between the DS spokes empty? That looks to be how Campag do their 3 grouped lacings.

The spoke holes are offset for drive and non-drive side spokes from the hub. Being a 2:1 hub you will need a 2:1 rim. I've built a triplet laced wheelset and had to do this. Personally, I wouldn't pursue your plan.

28H with every 4th hole omitted could technically work, and I vaguely recall a number of Campy rear rims with a similar 7x3 spoke spacing, but I'm not sure I'm down with the idea of having those spoke holes open to the elements and able to permit dreck to enter the rim cavity.
If carbon rim brake rims are acceptable, maybe a Chinese carbon supplier can do a custom drilling? They seem quite accommodating, it would just take a few additional eeks for the custom order instead of buying ex-stock.
However, unless the hubs are something special, or something else is driving the decision process such as a desire to be "period correct" it might end up being more cost-effective to build up a completely new wheelset with something more conventional say 20H front 24H rear.

Have always ended up getting spokes from eBay or Germany

I have always ordered my spokes from Starbike.comfamilyguy wrote: ↑Sun Mar 31, 2024 6:55 pmWith Pushys/Bikebug having zero DT Champion 2.0/1.8 spokes in stock in the lengths I need. Any other local suppliers for DT that have decent stocks? I need 284mm and 285mm. I've looked around and may have to go for Pillar via BDop instead if nobody turns up locally.
I see they have The DT Champion in stock for 284mm Lengths. DT only does even spoke sizes, so there is no 285mm spoke option. You'd need to decide whether 284 is long enough, or whether 286mm is what you need.

DT does do odd-numbered sizes, however they are basically non-existent in Aus. Additionally, most Aus online shops have pretty poor spoke ranges, so you're better off either actually going to a real shop (remember them?) or overseas. The Germans usually have the best range, but come at the cost of expensive and often slow freight, so ultimately you don't really save much, if anything. I've often used customcutspokes.co.uk for stuff that's been hard to get here. Their unit price is a touch more expensive than the Germans, but freigh is a heap cheaper, so they work out better-priced overall.

I thnk you're mixing up your Champions and Competitions.... Champions are straight-gauge, same thickness the whole length, most commonly 2.0mm, while Competitions are the butted 2.0/1.8mm model. Comps are the better choice, as having a bit more stretch along the length of the spoke reduces stress on the ends, building a more resilient wheel.familyguy wrote: ↑Sun Mar 31, 2024 6:55 pmWith Pushys/Bikebug having zero DT Champion 2.0/1.8 spokes in stock in the lengths I need.

Really? In all my years of wheelbuilding, I have never been able to buy an odd length DT Swiss spoke.

I ran the number on the spokes above, and they are selling for 50c a spoke. How much does one of those go for in Australia these days?
I know when I did my last set of wheels a few years ago, I went with DT Aerolite spokes and they cost me, after shipping and tax, $3.28 per spoke vs the local cost of around $5 a spoke. I can see Pushys selling them for $6.15 per spoke vs $3.47 from Starbike, so for a 72 spokes it's a bit of a saving, provided you are not copping $70 shipping just on spokes. What I usually do is load up my cart with everything I need to spread the shipping cost about, as it tends to be a flat rate for shipping.
