New build, arduino, motomonster, 2dof

Started mounting things on some wood, going for a rustic look. I may swap this out for some thicker hardwood for the final assembly.

that wood will surely flex. I would go for something thicker

This first version is to simulate waves and rocking for my infant son, I'll definitely switch to a beefier base down the road when I convert it to a sim.

Its a start mate, improvements and mods can come later for sure, keep going man.

I would be astonished if those square steel tubing brackets flexed, I think the bolts would tear through this wood before that happened. I'm not finished with motor braces, these only secure through one bolt hole on each motor. Maybe I'll run more square bar around those two bolt holes that are perpendicular to the shaft, tomorrow, along with brackets for the pots.

Yeah, I agree. However this first version ends up I'll be monitoring all the mounts and welds during testing to ensure that they are weathering the forces appropriately. Being so new to welding and these power house motors I'm not sure what to expect from anything

I guess I could weld a couple more sections of tubing to connect the two braces where they overlap in the center there to give them some lateral strength.

I 100% agree those Mounts need to be beefed up BIG time,

For example The small Angle on the left flexed on me, And i Initially though it wouldn't be possible.
Also how thick is the plywood your working with ?

That plywood is about 3/4", but I'm not sure I'll keep it, just wanted to mock everything up on something. I'm hoping to grab some nice hardwood, walnut or the like, for a better base.

That would be the best route I agree, however I don't have the additional time it would take (or the time to run sims) at the moment and I've already spent more than I should on this project So I'm trying to wrap it up for it's current purpose while keeping parts transferable at least as well as treating this as a learning experience so that when I do upgrade to a full desk racer I'll know exactly what I want to change and what will work better, most likely just have to upgrade the fabricated hardware and braces.

Not to mention I have to do all the cutting, grinding, drilling and welding in my unheated garage which is currently at -12°C

Some more work, joined the two braces for lateral support and added mounts for the pots. Some sloppy welds in the tight spots, can't get the angle grinder in there.

Yeah, I still plan on adding a second mount point through another 1 or 2 motor bolt holes, just didn't get around to it today. I don't see a problem with the pot mounts, if the motors flex too much the pots are going to get wrecked no matter how they're mounted, I'll run it with some cheap pots first and see.

WHY cant you just make a Triangle bracket and utilize all 3 mounting holes, Thus Eliminating the chance of even remotely damaging the pots, Your welding skills seem fine.

One of the bolts attaching the gear housing to the motor is in the way of creating a brace for mounting hole #1 in the photo, also hole #3 in the photo is just a little too high for the square tubing I've got to reach without making an L bracket for it. Could you describe further what type of triangle bracket you mean? I numbered the mounting holes to help with descriptions.

Very Crude, and Not a triangle at all, Lol sorry about that, Overall tho you just need get at Minimum a 2nd bolt through, 3 isn't technically needed but if you can, Why not.

I'll probably go with something like this, though I don't have anything that will cut curves on steel or weld plate thicker than what you see, so I'll probably stack two pieces of the square tubing I have, weld them together and to the existing brace then bolt them to the motor and base.
