An excellent result and very enjoyable thread well done, having a silhouette certainly made it easier in respect of making two sides the same height etc, unfortunately i dont have one and went down the etched brass sides (got them made privately) for some Irish bo-bo Sulzer loco,s i built some years ago. I wouldn't worry about a discrepancy of 0.5mm in height or any other dimension of your build as your model has captured the real machine beautifully and captures the imagination even more as your video shows.
