| An O Scale Sand House. A follow-along, step-by-step scratch building project Part Deux. |

| You'll notice that the grain swelled up and the boards don't look as distressed when dry; do the saw trick it again if you wish or use the boards as is. I did it again to a few of them, there is less "de-fuzzing" to do this time around. |

| The 2 x 12 boards: Cut 5 lengths 4 inches or 16 scale feet long. Cut five lengths shorter by the thickness of your posts, cut five more 2 inches long, see picture 1. >>>>> |
||||||||||||||||||||||||||||||||||||
| The 6 x 6 posts: Cut six lengths 1 1/2 inches long or six scale feet. Cut eleven shorter lengths, mine reach almost the top of the side walls which are 5 scale feet high. |

| Take the six long 6 x 6 posts and drill two holes in each so they are at right angle to each other. We will be threading the .030 brass rod though them. This is where the reamer comes in handy and to eyeball for squareness (since I don't have a drill press). The bottom hole should be slightly higher than the short posts are tall so the brace clears them. No problem if all the holes don't match exactly, you can see in picture 1 that mine don't. |

| Start assembling the two long walls making certain everything is square. NOTE that the two are mirror-images and that where one has a short length the other has a long one. All five boards are staggered long-short, long-short but are flush at the end where they meet the house. Glue a long post flush with the edge, all top holes are perpendicular to the walls and all lower holes are parallel. Top boards are distressed |

| on both sides. Continue by gluing a short post flush with the short board ends on the right (left for the other wall). This will hold the assembly together while you glue the other posts on. Next put a scrap piece of 2 x 12 next to the long post as a spacer and glue a short post to the wall. Glue a long post right in the center of the wall. Is everything square? Do the lower holes clear the top of the short posts? Continue with the short wall, note staggering. Pictures 3 and 4. |

| As you can see, the wall sections will fit together like a jigsaw puzzle. The two long lost left over will go in the corners after assembly. I decided to be a little more conservative when it came to how dilapidated the structure was going to be. You will see in pictures 4 and 5 that there are two broken boards. The bottom corner is rotten because that is where water accumulates and a top board is broken due to an accident. That was done using thumb and forefinger and scale brute strength after assembly. |

| This is a good time to make sure the .030 rod fits through all the holes, that all the holes face in the correct direction... MINE DIDN'T, and that it all fits together well and square. Let's move on. |

| The inside of the bunker will have sand in it, but first I built up several layers of foam core. I could have also used balsa boards or foam insulation, use whatever you like. This adds strength to the model, saves on sand and gives you an idea of what it will look like later. You could make yours with more or less sand, with a more central pile with the center brace half buried. Go for it, it should look natural though. |

| I just love the product called Blacken-it by A-West. I shined up the lengths of brass rod, dipped them in the solution for about fifteen seconds and dried them. They are now black so that if the rust paint I apply later on ever rubs off there won't be shiny metal showing. At this time I also painted the NBWs rusty, we will need eight. See how the long brace at the top is bent where the board is broken? |
||||||||||||||||||||||||||||||||||||
| Cut two long and three short lengths of .030 brass rod. Measure from center to center of the end posts for the short rods, this will leave room for the NBWs. The long ones have no NBW at the house end, NOTE the bent rod should be a little longer and should be bent after assembly. Thread the long sections through the three tall posts, glue one NBW at each end then glue the rods in ( I used a small drop of thin ACC applied with a pin). Do the short ones next in the same way, paint with rust. I hadn't gone that far yet when I took the picture. I also noticed that some of the bottom boards weren't distressed or weathered and they show, that will be rectified before we move on. Next: we start the sand house itself. |
