Hi all, thanks again for all the input! Today I made some good progress I think.

@Overkill I was intending to hollow out the bulkheads yes, and I have done so now!

@Maddox, that is good to hear, I think I have settled on the bronze bushings now, as I need to get the weapon blade cut very soon!

So tonight I was able to redesign the bulk heads and remove the other set of bulk heads that were no longer needed. I've also decided to ditch the belts and use the linear bearing mounts for hubs directly to the saturns.



As you can see, I've also inset the weapon drive motor, bringing it closer to where the pulley will be, and I have also offset the blade to one side so that I can side mount the pulley to it. The motors now sit ontop of solid nylon blocks to make them centered to the chassis, these will also be good shock absorbers.
Please ignore the gap in the front wedge being off center too

Next step for me is to angle the back of the robot and make it fit tighter to the wheels, so that when flipped it will still move (just about) to avoid count out.


I've found a supplier for 5mm grade 5 titanium & jet cutting, so I will probably be making all the armour from this and a 3mm plate for the bottom. I might still use a hardox wedge if I end up with enough weight left. Bulkheads will be 7075 alu.
