Determining spoke length?
Looking to build my first set of wheels but I'm not really sure about spoke length. Gonna be DA-7600 28h to TB14

It's always best to verify measurements even if there are user submitted dimensions

Now, is there a way to tell if these hubs were laced 2x or 3x previously? I'm assuming they were done 2x

There's also this calculator: https://online2.qbp.com/spokecalculator/
Which you can use to verify the numbers from Edd.

I went to https://www.prowheelbuilder.com/cw/ and got the measurements for the spokes when I built Archetype with Bitex rar/raf12... and bought somewhere else....
The TB14 is there, but you don't have DA7600 hub...

Will the rear hub being single fixed affect anything?
It doesn't center up like a fixed/free or fixed/fixed hub does

Prowheelbuilder had the DA high flange track hub aka HB7600, just not a 28h

Spocalc is already somewhat a library. I just add to it when necessary.
You might be able to tell if those were 2 or 3 cross based on the angle which the spoke grooves are formed, coming out of the spoke holes. To me, based on your photo it looks like the crossings were different for front and rear. Maybe 2 and 1, or 3 and 2.

My main concern is the single fixed.. looks like it may need to be dished slightly

The first build is a bit of stress. It gets easier.

You can see that the rear hub doesn't center the way the front does
This is about centered.. slightly off

I have only built 10 speed wheels but pretty much would expect the right flange of a fixed gear bike to also sit closer to center-mass and therefore require shorter spokes for the drive side.

According to Spocalc, for the DA High Flange hubs, the DS flange sits 11mm closer to center mass than the NDS flange. It does not indicate whether these are the DA HB-7600's, so you will have to measure or get the measurements from a known good source.

Since these hubs have been laced before, it would be good to make sure that you lace leading and following spokes into the same places they were before. As long as you do that, going from 2x to 3x or vice versa shouldn't pose a concern.
P.S. I think @pressed001 is on the right track with the number of spoke crossings. Rear impressions look pretty tangential, while the fronts are a little less so. Maybe 2x in front and 3x in rear? The front may have already been laced more than one way, it's hard to tell.

Ok.. did some more searching and got the measurements
Front:
Center to flange - 34
Flange dia - 67
Rear:
Center to left flange - 41
Center to right flange - 30
Flange dia - 67
Rim:
ERD - 610
OSB - 0
Seem about right?

Figured the spoke length out.. thanks a ton guys. Any suggestions on spokes now?
I float around 200lbs so I'll probably go 2x front and 3x rear
Front:
2x: 286 l&r
3x: 300 l&r
Rear:
2x 287 left/ 286 right
3x 301 left/ 300 right

I built it with Sapim Laser and brass nipples for 20 front and 24 rear and very happy with the wheels. I am at 140 lbs.

Always good to measure what you have before ordering spokes. There is disagreement online about the correct ERD for those rims, and whether a given measurement includes the head of the spoke nipple. Sometimes parts vary from lot to lot, as well.
