A decent amount of years ago, a friend of my family was killed by a drunk driver. Since then I have picked up on multiple things of his life, including bass guitar and skateboarding/longboarding. I got home the other day and this beauty was in my garage; it’s his old mountain board:
I managed to get all of the bearings out and off the axle, but everything was rusted together and I ended up chopping my wrist pretty deep in the process of prying everything apart.
Anyways, the wheels have a nice pattern on the inside that would go well with a mount and my plan is to electrify this, make it look awesome again, and give it away. I’ll update as this moves along!
Lot of nice stuff from @JLabs here, the motor in particular looks fantastic. Does anyone know where to get the screws for these to go to the motor mount? The kit didn’t come with anything so I don’t know exactly what to use…
As you can see, the wheel is so monstrous that It hits the motor even at maximum extension of the mount. The way I see it, there are three options:
Get a longer motor mount
Dremel away part of the wheel
Get some more green MBS wheels (black is out of stock )
Any other suggestions in solving this issue would be greatly appreciated, I think I’ll likely go for the dremel option as
money is always something in the back of my mind with this hobby
@treenutter the space needed is only a few millimeters, I am considering today just dremeling some of that edge on the wheel. It may not look pretty but if it works, it works.
Finished the drivetrain - it’s not perfect and it’s REALLY tight but I think it’ll work for now. First rides will determine whether or not I created a belt-shredder.
Nice job man. I’d have a hard time giving it away if I were you.
I just wanted to mention that excessive belt tension can be hard on the motor so be sure to take care of that at some point.
Keep up the good work.
By tight, I meant the amount of space in between the motor gear and the wheel itself (it’s less than a millimeter). However, the belt is relatively tight as well so I’ll keep that in mind. Thanks!
Nice to see some old stuff getting new life, too bad the trucks couldn’t be reused as well.
I’d suggest turning the motor so the wires come out toward the truck instead of the board.
Otherwise you’ll most probably end up with a short in the motor if the phase wires don’t have extra insulation inside the can. (Personal experience)
@Iceni thanks for the feedback! I am curious regarding your suggestion to change where the motor wires are facing - I’ve been running an SK3 on my Semi for a few months now in a similar configuration with no issues. How exactly does the motor short itself if the wires are in this particular position?
When turning, the phase wires might move in and out of the motor can a small amount.
Which may rub the insulation off of the strands inside and cause them to come into contact with the metal inside. And if it happens to two phases the motor will short circuit and possibly take the ESC with it.
I’ve had it happen and I’ve seen one or two others on this forum which had the same thing happen.
One solution if you want to have the motor in that position and mitigate the risk is to cover the wires inside with heatshrink all the way to the coils.
But for that you most probably have to open up the motor and that might not be worth the work involved.
Hence when I see someone with that configuration I at least point out the possible danger of it.
Well, most people would say that you should go back towards the truck then around back to the enclosure. However, I think that the position you have it in now should work but I could be wrong.
Anyways, the wheels have a nice pattern on the inside that would go well with a mount and my plan is to electrify this, make it look awesome again, and give it away. I’ll update as this moves along!
