Wheel hubs?

[David Ham]

alright so I have a problem. I have some 145/70-6 wheels, and a 25mm axle. I have looked and I can't find anyone that sells a hub for these wheels and axle. The only hubs I have been able to find are for splined axles, like in the picture.
so might need to make my own, but I have no way of cutting a keyway into one if I do make it. I might be able to use a file, but I'll be needing 3 or 4 hubs so thats probably not practical...
so does anyone know if such hubs exist?
thanks!
if not, I'll just have to make my own and hope for the best...I have done it before

Instead of cutting your own keyways in a tube, why not find a solid keyed shaft coupler? One should be long enough you can cut in half, and weld the halves to a piece of plate that's cut and drilled for your bolt pattern.

that would work great, if I could find some.

 

[David Ham]

this is all I came up with

Buy a hub that fits the axle.
Cut off the flange that has the correct stud holes and weld it to the hub with the keyway. Done.
Here are 2 pics of hubs I did like that....only opposite. I needed the spline shaft.

that would be another option, but the only wheel hubs I have been able to find are aluminium. I've contacted a machine shop and hopefully they be able to do it. if not, I guess I'll just have to use a file...

There are lots available online... I googled "25mm solid shaft coupler"

Obviously shipping to Oz would be horrible, and metric anything in the US is automatically 4x the price, but there's got to be something like that available locally.

Any motor/pump supply houses in your area? Sometimes the trick is to just go in and ask.

hmm yeah the nearest place is not far away but I just had another idea, I might be able to cast some hubs out of aluminium. Obviously they would have to be pretty beefy to make sure they don't break, but its probably worth a shot. And I can test them for strength before using them also.

You could use 25mm racekart hubs like these if you drilled new holes in your rims to match the bolt patern:

I can't drill holes in my rim because the hole in the middle is too big, but I could make an adapter plate that bolts onto the rim and then to the hub, that could work...
should have though of that really

 

[anickode]

Maybe buy a set of 6" rims that has a more common bolt pattern?

When comparing it to multiple options that will all require machine shop work, it will be cheaper.

No need to reinvent the wheel you know (ha-haa!). Just find better wheels if at all feasible.

 

[David Ham]

yeah, I should have gotten different wheels, but I also could have gotten hubs for $30 along with the other stuff, but I didn't think I would need them
now the cheapest option is $60 for a pair... and wheels would be around that much each. Making a plate that bolts onto the hub and then the would be the easiest option, but I'll try casting them first, if that doesn't work I might buy the hubs...
