I used a heavier headed hammer and a socket and installed it on a carpeted floor. Tapped it a few times to get it started. It went in a little crooked but tapped some more on it with a screwdriver and it straightened out enough. Be careful not to go too deep with the star nut or the bolt won't thread. I was about 1/32 to 1/16 inch too deep to get it far enough threaded into the star nut, but fortunately the headset adjusting collars were carbon, so I was able to scrape one of them on a flat sidewalk to grind it down evenly to reinstall the headset. I know the star nut won't come back out the top as deep as it went in and I was able to thread deep enough into the nut so it won't loosen up during a ride. That's the key to a proper installation, the right depth for the star nut and it going in and aligning straight enough.

Yeah, realize the thread is from 2002, but just adding another method. I got mine to go the first time, a little better than 2 of 5 from the prior post.
