I finally found the box with most of my modeling tools and found a 36" X 30" area to work on. Now I am checking ALL the trains and slot cars for damage after being temporarily stored for 25 years. Most of these posts are not going to be anything earth shattering, but, maybe might help someone in some way. I am going to use this thread to help overcome the inertia of 25 years being idle. Many questions will be asked; any comments will be appreciated.
Opened first box. First project is 12 Tyco #342A Western Maryland skid flats and eight culverts. I decided the would be a great for my son and myself to learn the new CAD program and 3D printer. Haven't had much time for it lately.
Laid out 2D footprint for a set of three culverts. Since there isn't enough surface area on each culvert to hold it to the printer bed, a larger surface area had to be created thus:
This should hold it in place. As time permits, the framework will be made 3D and the culverts will be designed. For the moment, learning design considerations and commands are priority on this project.
Second project: 13 Tyco #342B skid flats and two damaged culverts. Two flats had deck damage from glueing loads to them.
To hide the damage, I decided to make stone loads. The first is a marble load from a picture of a Vermont marble company transferring stone from their quarry from Colorado. Came up with this:
The wood planks in the background will be set under them when they are trimmed for the shape of the deck. This load, according to the caption under the prototype picture, does not need any type of restraints because the weight of the stone creates a coefficient of friction of friction high enough that the load doesn't move during transport. This makes this load quite easy to make.
The second damaged car will have a red granite load. In this area, red granite is a big commodity. Although I have never seen it hauled by rail, it has been hauled by flatbed semi-truck. Close enough.
Loads are made with 5/8" drywall scraps with the paper backing soaked off, dried out, glued together if desired and covered with a soupy spackling compound. The trick with the granite ( orange to dark red from iron content ), is getting the hornblende ( black ) and quartz ( white ) 'spots' in scale. The shiny spots are reflections from the crystals that formed in it.
