Before receiving the arms torque from BMSBattery, I were preparing the fork dropouts and the washers. On the disk brake side I don't get room to a torque arm, to say the true, there is even not enough axle for the nut:
And on the other side, I get about 8mm free of axle. Note that since I have space, I am using one of the strong (4mm thick) "C" washers that BMSBattery sent with the motor:
And today I received the BMSBattery arms torque
made of stainless steel:
On this side I have enough room for using 2 arms torque. I want to weld them on the local of the screw so they can't rotate on that "joint". Since the wheel will be moving forward, the torque will try to move the axle backwards and so I think this position will be the best since arm torque will be pushing the fork. Maybe I can weld also some bigger piece of metal in the end of arm torque to spread the point of contact/force against the aluminum fork.
And here a picture showing the other side of Bafang BPM 500W motor and not enough axle to hold the torque arm and the nut...
Please give me ideas, your opinion on what would you do on this situation were I have this material: the nuts, washers, arm torque and aluminum fork.
