wheel building - too tight, too soon
Hello! I'm building wheels for my bike. Part because my bike has steel rims, that render it basically breakless... and because I want to learn how to do it.
It's a 27" rim (Schürmann 630-16) with a Quando hub on the front and a Maillard hub on the back. All very cheap, I know, but it's I could get.
Spokes are stainless steel. I forgot to ask in the shop which size they gave me (I left everything in the shop to me measured).
I started with the front wheel, 3-cross. The pattern is okay, I already more than triple-checked it. but the spokes are already very tense even with some threads to go. Is this normal? Sheldon gives as an example for the initial tensioning, turning the nipples until the threads disappear -- I can't do that using a screwdriver, there's just too much tension already.
I can still squeeze them, but not that much...
Should I start truing the wheel or is it possible I'm not seeing this right?
