Finally did my drop header

I had planned on this for several years and I finally got the time and ambition. The boiler was installed in 2011 and the plumber did a quicky job on the near boiler piping. The result was loads of carry-over water and serious water hammer. So I bought a used Ridgid pipe threader tool set, a pipe vise, and all the fittings. I unscrewed all the pipes and I needed my Ridgid compound wrench for many that were badly rusted. Quite a few were able to be re-used and I bought all the rest new. I used Dan's books and the posters here to design a drop header that would dry out the steam yet conform to my existing main piping and the tight space limitations. I used flanges at the boiler exits and in the middle of the header, and swing joints where I connected to the mains, to allow for expansion/contraction. While Dan says you need at least 24" in the "A" dimension, he wrote you should go "as high as possible" so I went for 48". I used both 2" exits on the boiler to slow the velocity and expanded to 3" at the header. The two main take-offs then again climb 24" up to the mains. I used plenty of strap steel supports as these pipes are pretty heavy. I used Permatex anti-seize on all the threads in case I needed to take any apart later. The anti-seize worked great as a thread lubricant and the pipes sealed so well, not a single leak. Now my steam is dry and the system is working better than I even expected. Thanks Dan! You were absolutely right! Many thanks to the posters who contributed pics and ideas about drop headers. See before and after pics.
