you would figure that with all us high power hub motors that someone would of thought of doing this years ago, finally you did, can't wait to get the torque arms for the trike and use regen!
i will go with the epoxy as it is truly amazing what that stuff can do, and i will not risk messing up the weld
Using weld steal to steal is good, using screw and nuts is good and EPOXy is good too IF YOU KNOW HOW TO APPLY IT CORRECTLY.
For those who doubt about the 3M DP420 epoxy, please watch my video of my ebike towing a 14000 pounds bus.. and think about it.. it's that epoxy that retain the axel of my hub motor ! !
I wouldn''t trust the epoxy and would have done the steel to steel with a proper tig welder. You are dealing with a critical part so you go for a overkill on the torque arm but underkill on the attachement. Be carefull.
@turbotrana The torque arm steel is made to avoid the deformation that could be caused by the axel, that's it I can ensure you that after using 15000Watts on these motor and 4000Watts of regen, making the axel working in both direction, that the 3M scotcherld epoxy IS the simple and efficient solution. it's average of 4000psi shear strengh and the surface of the torque arm is aroud 2 sqrt inchs so that's 8000pounds max you can get of shear resistance. please rear about it.. DP-420 scotchweld 3M
Thanks for the video Doctorbass. I made my own torque arm and don't use the super hard steel that you are using but still it is very hard so I hope it will not get lose. It doesn't have a perfect fit but nearly perfect. I use HS motor with 72 volt and I can now enjoy the ride. The only thing that I need to do is to buy a new front fork so that I can install disk breaks. I have no idea how to do that. I'm going to find help for that.
Hello there doctorbass, nice tip, I am at this exact momment designing a dropout for a open source electric bike frame (project emoped). I will take your idea into consideration when finalizing the design...would be very cool to have your feedback. cheers, Henrique

What do you think about using JB weld or quick steel?
