Cat 340D Excavator build

[crueby]

Another major assembly almost done - got the track frames/tracks assembled this afternoon, moving quite well. Still some more trim panels and brackets to go on, and need to pull the tracks off one more time to install the drive chains and sprockets on the inside. The chain sprocket on the center of the track drive sprocket is there, but there is another one in the center of the frame that still needs to be fitted. The drive motors will sit on the inside edge of the track frames, under the middle of the cab (one per track). As mentioned early on in the build, these are NOT true scale tracks for this machine, but are re-purposed from a RC Tiger tank model - getting me running a lot sooner, to see how the whole thing functions. They can be replaced later with better scale tracks if I get the time for it.
