      Scott,

      Thanks for the coin comparison. I couldn't do this small detail 50 years ago...Amazing!!

        Scott excellent job so far!! I have enough trouble scratch building in O scale; besides these old eyes could never focus on something that small. This should be very educational. Keep going.

              Another of my projects that I have procrastinated on. Again I was nervous about soldering this.

              I watched a very helpful video on soldering brass.

              I used 50/50 solder and acid flux (I know, I will have to give a vinegar bath). I first soldered an internal sleeve to hold the end caps at the right depth. Then soldered the caps and dome base in.

                  I suggest you get some 63/37 eutectic solder; it will melt all at once at 360F. I'm using an old roll from Radio Shack but Kester sells it in several small diameters. Rosin core hasn't interfered with my use of Tix flux.

                        Another point - cleaning up a grease-based flux like 'NoKorode' is best done with soap and hot water. The soap is just basic enough to neutralize any acid that doesn't get washed away. Tix flux is also acid (zinc chloride solution) but it's easier to wash away residue.

                            Snuck in some work on the tank car.

                            I stuck the brass frame piece with double sided tape to a block of wood, so I can drill and cut slots to create the frame.

                            I ended up screwing the brass down because it got hot while cutting it and the tape melted.

                            I used a thin cut wheel on the Dremel.

                            Next will be drilling some more holes and filing out the open areas.

                            I will be printing the wood deck on paper that is the correct thickness in scale.

                            I used some wood images and Photoshoped them to create the deck. I layered that over line work I created in Illustrator using

                            a tank car drawing from White's car book.

                              I finished the open areas in the frame, and cleaned it up. I then cut strips to represent the different cross beams, 5x5, 5x7, 5x10. I started with the biggest beam which supports the queen posts. Because of scale, I made the posts and beam one piece.

                              After I solder the beams on, I'll attach the truss rods.
