After lacing the wheel, the first thing that I do is to stick my thumb nail into the last spoke thread and run the nipple up till it stops. That starts each spoke at the same point. Then I build tension into the wheel by counting the same number of turns on each spoke. I once built a 40 spoke (dishless) tandem wheel that required no truing at all using this method.
Most of the wheels I've been building lately are deep section carbon rims. I tried long toothpicks and kabob skewers for inserting and starting the nipples, and then I tried a Wheels Mfg nipple starter. It locks onto the nipple so you can put it down into a deep rim and get it started.
It worked well in theory, but it did not really hold the nipple securely, and I'd often find myself shaking a loose nipple out of a rim.
Then one day, a friend of mine was here visiting while I was building a wheelset. He saw the tool I was using, and said," hey, that looks just like the screw starter tools I have."
He is a retired industrial instrument installer, and has all kinds of cool tools he no longer uses. He went to his car and came back with one of these.

I've been using it ever since and never lost grip on the nipple, even in rims as deep as 80mm.
