Just a slight update on where things are.
That's why it might make sense to go with 2 motors! lol You'll pay one way or another. That said, I'd go with the manual transmission route, since you are clearly good at fabrication.So I've been playing with the idea of just locking the diff and putting a clutch on each side of it but I can't seem to find a stand alone clutch. That or my google skills are lacking. I looked at electronic clutches but that is not really what I need as I need it to ease in and out not just lock. I was debating of taking a regular clutch and the fabricating a housing and the clutch inside with an output and input. It shouldn't be too hard would just be a little pricy to get cnc'ed. I also thought about just getting two manual transmission cutting them up but that seems like to much a hack job for what I need.
If anyone know anything that would be amazing!
Yeah I've been playing with a ton of ideas with this guy as I work on it and how to save space in the actual tank and make it comfy for 4 people. My latest "idea" is have have the motor run a hydraulic pump system and run a articulated trailer in that it will hold the HV batteries and extra storage. I like this idea, as it makes running each track, turret, trailer all off a couple pumps. The only thing I'd be worried about is speed. I'm only shooting for 25mph but I'm not sure a hydraulic pump can reach that.That's why it might make sense to go with 2 motors! lol You'll pay one way or another.

Yeah I talked with the shop and they are giving me a discount on the next time I order and whether I get 4 or 6 it will be the same price - once I hit a threshold on price it just caps instead of getting higher. I'm ok with the aluminum - it will last a very long time with it being so thick and with it being most likely powder coated it will protect it from the elements. Plus almost all swing arms - a arms and suspension parts are made from aluminum today. I have a 12 year old motorcycle with aluminum parts and still going strong.Ouch, rough man. (For those that didn't watch, he spent $1300 on 8 custom CNC'd swing arms, but forgot that there is a left and right side and the parts can't be clones, they have to be mirrored. So 4 of them will work, and he needs to order a mirrored set for the opposite side).
I get that you want to use up everything you paid for, and add more so you use 6 of them so there's only 2 "wasted", but... now instead of ordering 4 new mirrored ones, you have to order 6 new mirrored ones. This just directly adds to your mistake. You're buying 6 instead of 4. Even if you'll have 4 wasted, you'll still have minimized the cost of your error if you stick with 4 like you originally planned.
I'd say that since the design just needs to be mirrored, that perhaps the CNC shop would be willing to give you a deal, since the CAM and fixturing work should be fairly minimal on a mirrored part. Also, they may have some sympathy that you fucked up, and decide that unless they're booked 24/7, to run them for you at significant discount in their downtime.
Another thing too late to consider... aluminum never hits a fatigue limit. Unlike steel, it fatigues and degrades forever. It might not have been a good choice for a swingarm in suspension parts on something you want to use more than just as an occasional demo. It's carrying the weight of a tank and getting beat up and bashed around and taking the force of running the machine. It's definitely going to be stress cycled to failure, it's just a matter of, to what degree and how quickly.
That is very cool! See this is why I love the community - so many amazing ideas and smart people.Sorry I know the conversation has moved on since discussing the steering using individual brakes. But I made this unit from two hydro handbrakes. It works very well. Each cylinder operates one of the back brakes. Pushing the lever forward turns right, pulling back turns left.
