Question dual 775 FFB wheel

Hello! Starting my first FFB wheel

i have acquired:
2x hanpose 288W 775 motors
2500 pr rotary encoder
arduino leonardo (DM diymore)

i need to get (help needed):
power supply (watts?)
2x belt pulley set (ratio?)
motor drivers - 2x BTS7960
motor protection in case it stalls.
bearings, frame, screws... etc.
anything else important?

im having trouble finding the stall torque of the motors, i have done some math and came to a number of around 2.5 nm

1. For the power supply you should use at least a 300w power supply, I recommend 10%-20% more. People on this forum used LED power supplies, and had good results, or you can use a car battery that's connected to a charger while you are playing.
2. For the pulley ratio I recommend something like 20:1 reduction, because those motors are designed to spin really fast, they have a fan built in that doesn't work if the motor is spinning slowly or not at all, but there will still be heat produced as long as there is current running through the motor.
3. The BTS7960 should be good enough. I'm not sure but I think one BTS 7960 should be powerful enough to power two motors.
4. I don't think you need any motor protection that isn't built into the BTS7960, but don't quote me on that.
5. I am not an expert on bearings and all the other metal stuff so take this with a grain of salt, but I think it would be wise to use angular contact bearings as they can handle more axial loads.

The specsheet says 1 DC 775 motor can produce 0.294 Nm at 10 000 RPM.

damn that think will rip your arm off or at least a finger!

Would you say it's a bit 0v3rkill?

hello.. in the past I use the 775 motor too. but I think its torque a little weak than a single MY motor (right now I use MY6812 motor) and its more easy to stall and burn the BTS motor driver.
I use 8:1 ratio, using 120T 3d print pulley and 15T on the motor. and its produce more than enough torque, better than T300 (from my experience).
If I may give some advice, it'll better to use single motor, its more cost effective and easy to build.
here is my setup.

what is quote, this button is also at bottom i think this is to save the forum and press it multiple time to save it, i don't know exactly abou it, please tell me
