    mounting a hub-motor, torque-arm, .. man thats hard work

    hmm.. Variante 1 ist zu teuer :( Variante 2: da feil ich wohl 2 Wochen dran rum, oder ? kenn mich mit Metallen nicht so aus.. ich habs mehr mit Balsaholz und aufgrund meiner langjährigen Balasa-Holz-Erfahrung kann ich sagen: so eine Drehmoment-Platte würde aus Balsaholz nicht halten ;)

    mounting a hub-motor, torque-arm, .. man thats hard work

    yeah.. question is, if it is easy to make it when it is closed... maybe it has to be done in 2 parts.. so its easier to machine it, and afterwards screw the two parts together, quasi a "door" for the slot

    mounting a hub-motor, torque-arm, .. man thats hard work

    this idea came to my mind, first time i saw the torque-washer and my fork.. question: would it be strong enough, when the plate for the 10mm slot is on one side (of the slot) open ?? i mean: thats the same like the fork is made.. but otherwise making would me much harder i think..
