Building my own wheels and making sense of the spokes length (self.bikewrench)

I want to build my own wheels.

What I got so far are the rims: https://www.flybikes.com/product/fly-lunar-lite-rim-black/RLRL03

And some potential hubs: Rear: https://www.tritoncycles.co.uk/components-c9/hubs-and-spares-c120/hubs-c591/surly-ultra-new-rear-disc-mtn-hub-p9851 Front: https://www.tritoncycles.co.uk/components-c9/hubs-and-spares-c120/hubs-c591/sp-dynamo-pv-8-power-dynamo-ultra-small-front-hub-p11398

I would like to get some sapim spokes but all the online calculators online are failing me because I cant find all the data points they ask: https://www.sapim.be is there an easy way to do that? Should I order the components first and measure them myself? (I felt that is kinda risky as I want to make sure everything would be compatible first)

For the dynamo, a drawing can be found on the manufacturer's website: here

I can't find anything on the rear hub right now, you will just need to measure it yourself. As long as the spoke hole count matches, compatibility shouldn't be an issue.

I don't have an answer for you, but I'm keenly interested as I also plan to have wheels built and will need to do the same calculations soon.

Did you eventually find the data you needed, or did you buy the components and measure them out?

Im still in the process of learning more (i think ill get a book on wheel building and see how it goes)
