Fully adjustable stem, DIY project

Inspired by a few recent DIY threads (I always like them anyway), I decided to put up some show-n-tell pics from my current project. I`m putting together an mtb based tourer and built this stem to get my cockpit set up. The idea is to run with this one and move it around as I see fit until I get it to where I`m not tempted to move it any more, then build a set-height and length stem when I know how I need it. I did the same thing with another bike and it worked out well. This one has a different size steerer, so I needed a new adjustable for it. I got the idea for it from Josh Putnam on phred.org, who got it from an old track stem he had apparrently seen.

The first picture is with the original hardware on the bike.

That's prettty cool. But, I'd think about something on top of that tube, like a chair tip, to keep that tube from impaling you in a mishap.

I like the idea alot. I have thought about a similar set up. I have a few questions if you can spare the time to talk about your handy work.
How many miles/hours, do you put in untill you have the fit dialed in?
Do you Tig them?
What is the steel?
What do your finished stems look like?

You aren`t the first person to be horrified by that thought. I haven`t taken this one out on the road yet, but I guess I ought to cap it somehow when I do.

Ebr, I love to talk about it. The last one was for a commuter and I guess I had it on for about a month/200 mi. In that case I really didn`t make any meaningful changes after the first two days. This time I expect it to take longer because I don`t have much experience with drop bars and I`m not too sure I`ll be able to tell right away when it`s in the "best" (or close to best) position. Until about six months ago, all my projects were TIG welded just because that`s what I`m most comfortable with. Since then I`ve been getting better at brazing and I like the look better, so this stem, my latest rack, and most everything in the future will be brazed. The steel for my stems is drilled out cold roll (plain old off-the-rack steel). Pics below are the "final product" from my last one. It uses a regular allen head quill bolt- I just recessed it and capped it for looks. Thanks for your interest. I don`t know why these aren`t available commercially. It could even be done for a threadless system.
