| Dimensioning |
 I had to adjust the original plan just a bit. Since the entire thing was made up ‘on the fly’ based on some fuzzy photos for a hundred years ago it’s no biggie. I modified the frame to the sizes specified on the Evergreen Spec pdf. For the frame I plan to use Evergreen #278 – 5/16″ IBeam.

 The ‘feet’ can be made from some Evergreen #287 H-Column. Looks like slicing off the ‘bit in blue’ and welding on a couple pieces of .020″ styrene will work.
Note: One of the problems designing things like this is that the final product is very, very small. What seems to be a good idea at the time can be .. something else when you actually start cutting plastic. |

 … and here we go. Notice how small the four pieces of reinforcement plate are. According to my original mock-up in Sketchup these are riveted to the I-Beams. Humm. Will just have to see how that goes. I used .020-in stock which is too thick really. If I used .010-in not only would it be closer to ‘reality’ for thickness .. but it might be possible to emboss the rivets. I’m making a run to town today so I will drop by the LHS and might be able to pick up some thinner stock.
It really will not matter that much in the end as this coal breaker will be sitting under the coal tipple .. but I like to try anyhoo. |
