You said “only comments from people who have built wheels themselves” you never said “only comments from people who have built 4 cross pattern wheels”. Oops did I just reply? I’ve never built a wheel, but I have busted one and had it rebuilt by a Bike shop (twice).
We could add “reply to a thread from which you are forbidden” to the 240 ways to annoy people.
Based on the Uni.com spoke calculator, I would use the 246 with 12 MM brass spoke nipples. Note, DT nipples run shorter than most others so you will add 1 to 1.5 to the spoke length. Though I did build a Suzue/Alex/4 cross, I don’t remember what size I used. Current project: GB wide hub/home rolled 368 MM 14 straight guage/Semcycle nipples/Airfoil in a 3 cross.
Why are you asking us, Random Man? Having built three permutations, you’re the expert. Which length resulted in the spoke ends being just below the nipple slot after full tensioning? That’s the one to use.
That should be fine, does that extra mm acutally make that big of a difference, I know if they are too short your fu@$ed, but if they are too long isnt it just a few extra grams. As long as they dont bulge through the rim tape it wouldnt make a big difference would it??
I’ve used the Spoke Calculator every wheel (except the Coker wheels) without a miss so far. I wish I had taken specific notes too, but haven’t been burned yet. Except for that one time when I had a 32 hole rim instead of a 36 hole rim and didn’t realize it until half-laced… bonks self on head
