Here are the bogey parts:
From the side, notice the block that extends the bogey off the hull so it will be in the center of the track. Also, the back plate that sandwiches the bogey arms (need spacer where you can see the bolts going through):
What it’ll look like bolted to the frame (final version will have the road wheels and upper roller wheel of course):
So, I have one bogey (of six) completed, except for a spacer. I have most of the bogey arms done. And all the grey bogey assembly fronts, and backplates. Just need to finish drilling a bunch of holes, and cutting the big blocks.
