Hoverboard motors for Esk8?

Im currently modifying my hoverboard wheels to work on a scooter or longboard but i need a 17mm OD tube. any one know where to get it? Supposed to be used for the axle

somewhat expensive, and i dont love their site. but they have damn near everything

Sick! this looks helpful.

Im looking for a hollow shaft so the wires can go thru the axle. not sure if they sell that

emailed them, they dont have what i need lolā€¦

time to get creative

you dont need to to be a shaft, just a steel tube would proably work. http://www.mcmaster.com/#steel-hollow-rods/=125dxyn

possibly even aluminum depending on how you are planning on attaching it to the trucks, this stuff is even described as being used as a shaft http://www.mcmaster.com/#standard-aluminum-hollow-tubing/=125dz21

You werenā€™t kidding about those prices man I need to find a different solution.

I would say, just for testing, clamp them on to some trucks with pipe clamps or something. You dont want to throw a bunch of money into it just to find out it wont work :/

Thatā€™s true. Iā€™m gonna do a test spin up today, Iā€™ll just put a loose fitting bar in there and clamp it. Iā€™m modifying it to work on a scooter not a longboard. Maybe a 3 wheel longboard.

Ah, so are you trying to put an axle through it?

Yes. Iā€™ve already made all the adjustments and drilled the holes for it. My hub motors have two different size bearings so I ordered an extra 17mm ID bearing to match one of them. Last step is to find a fitting shaft lol. Iā€™ll work around that

If you dont have to have the wires go through the middle, mcmaster does have some decently priced shafts.

They either have to go thru the middle directly or I can grind out a small notch on the side of the shaft to have them go out that way. I could use a regular shaft.

It just has to be 17mm and they seem to only have inch. .669in Iā€™m gonna look if that have that

Damn, the closest they come in metric is 16mm http://www.mcmaster.com/#rotary-shafts/=125g9jn (click on metric on the left hand side)

Yea I noticed thatā€¦ Iā€™m gonna go to the hardware store for inspiration. I might just use 17mm round bar

Could you get different bearings maybe? or just shim it with some thin aluminum from a discarded beverage container? :stuck_out_tongue:

I canā€™t because then it would make finding a right fitting shaft even harder because of the bore on the core of the motor. The part that holds the windings. Iā€™m gonna have to stick with 17. I thought about shimming it but I donā€™t know how good that would be for motor bearings lol Iā€™ll keep u updated

What do u think about square tube??

Whatā€™s so wrong about this? Itā€™ll have two bearings on it and it fits okay

Iā€™m doing this Iā€™ll let u guys know if itā€™s a complete failure lol

Eh, I donā€™t see why it would be an issue.

Square shaft? Surely u can find a tube somewhere?
