Anyways why are we arguing about something other then the hubs? This thread was for the hubs not someone idea of dremeling a axle.
Okay so that was user error. I donāt know why people want to modify trucks. Those thing keep your wheels on and you going smoothly. Thatās like modifying the wheel bearing on a car to make it thinner.
Making something thinner in width and longer in lengthā¦ Failure happens.
tal = TC /J. Torque Radius and polar moment of inertia
I never said it was a good idea to do ANY machining to ANY AXLE EVER
Yes itās not always true if the material is over made such as a titanium rod versus a aluminum or steel rod. But in general terms itās almost true with exceptions.
theres many different alloys with either but regardless, after snapping the axle like I did, and having a really hard time trying to find anyone whoās done the same while normally skating, and since Iām not going to do rocket science testing to figure what exactly happenedā¦just gunna keep to the smaller motors. people can post and think about it till their head explodes but without real testing no one knows and Iād rather be safe/
itās surprising it happened because a lever is twice as strong if itās twice as long. these motors made the lever maybe 2.5 times as long and I assumed that a normal skate axle not being used for extreme tricks and stuff could handle that.
if you look at the link i posted youāll see itās very common. its not dremmeling the axle its cutting off the aluminum around it
Question: So are we completely ruling out that running the longer single hub motor with the shorter free wheel on the same axle may have contributed to this failure?
if on the other side of the hanger the wheel was longer it would add to the load on the axle with the motor on it. I think itās easiest to imagine the forces exerted when riding down a hill with a slightly concave surface like a tube as thatās the situation where the leverage happens and that situation happens. a longer wheel on either side will add to the stress on both axles.
