So, I wanted to get an idea of the travel, strength, etc of the bogey suspension and springs. Keep in mind the wheels are actually the small roller wheels that got on top of each bogey. But since I don’t have the actual wheels done yet, they are being used temporarily, and they worked just fine.
I know it looks like the Zapruder Film, sorry, cell phone video not that great yet.
This first vid is not real exciting, it’s basically me pushing down as hard as I could while holding the cell camera. I was very pleased, and it seems like it would take an extreme amount of weight to max out the spring. In fact, my guess is that other parts would fail before the spring would ever compress all the way:

So you may remember from way back when I was planning my hull design, I was going to use a cabinet for the sheet metal. It already has some of the bends I need, it’s the right size, etc etc.
Well, it’s not going to work exactly how I planned way back when, because the cabinet is too wide… but it’s not going to be a huge difference.
Here is the cabinet:

Ok, finally finishing up the bogies. I am currently working on the spacers that go between the front and back pieces of the bogey assembly.
The spacers need to be slightly wider than the spring and bogey arms, so the arms are free to pivot:
First I cut UHMW blocks to be about the same width as the spring. Then I drilled matching holes in each one to be bolted between the front and back of the assembly:
Then, so the spring has room to rotate and flex, I need to cut off the bottom, and bottom corners:
These go quick, there are only 6… so after a few more cuts, some routering of the edges, and after I get the bolts that hold them all together, the bogies will basically be done.
