When I first started making my first board, I first considered making my own hub motors like this but out of a tacon 160. I stop myself from doing it though cause I though I would need bigger and more durable bearings and also questioned myself on how I would attach the outside of the motor to the urethane of my wheels. I concluded that I would need to make a new motor encasing which I would need a cnc machine. I though it would be too expensive and not worth the effort so I didnt do it. Did you get bigger bearings? and How did you attach the outside of the motor to the wheel?
I used the original bearings. I think the big bearing should be no problem, however it may better to use some bigger bearings for the outside bearings. E.g. 688 bearings.
The urethane is tight fitted around the can. I still need to add some glue . So far the wheels don’t move much but one of them moves a bit when it gets warm.
I think I will add the glue on one side, so that I can replace the wheel when it is worn out.
I actually removed the bearing tube. The small bearings inside the stator are only used to center the stator. I used JB weld to glue the stator to the axle and aluminum.
Indeed, removing the stator is not possible. I hope they last
The idea of the amount of material taken off of those trucks scares me. Hopefully the stator tube and bearings can handle the bending load. I’d mostly be worried about the centre side bearing. Think you’ll be replacing that a lot. Otherwise, super cool build! Nice DIY skills and innovations.
The bit size was indeed smaller than the can. To press it on the can, I first put the thane in hot water to make it a bit more elastic.
For coring I used a hole saw for metal with a pilot drill for alignment. The pilot drill goes into the skatebearings. I sprayed water to keep the dust away and cool the saw. The bearings dont like the water, so if you want to reuse them you need to take them apart and dry them.
and was just sitting on the forum unnoticed…
