Hi Im going to build my own FW soon and I wonder how to fasten the wheels to the axle of the drillmotorgearbox? How have all you guys solved the problem and maybe someone have any pic of it?
I buyed Dominics drill kit, and the wheels are just to attach and then screw so its tight enough
The Australians also tend to use the infamous red wheels (basically a wheel with a hard plastic hub that screws straight to the gearbox axle). Though ordering from Australia might cost some money, they should provide more grip than Dominics wheels.
But the advantage with Dominics kit is that you also get an easy way of mounting the motor itself, which is a big plus.
I know that theres a place here in Sweden that also sell the red wheels, but at a fraction of the cost when compared to importing them from Australia (though I think theyre blue but otherwise identical). I will look into this, as it might be useful for some other builders as well.
Basically Get your wheel (make them out of 18mm plywood it works fine really!) and drill an 8.5mm hole in the middle. Then lock the drill so it cant turn and then you can simply screw it on and this will tap the wheel.
Nice 100mm diameter wheels are available from b&q and seem fine although not huge grip.
As for mounting them there are manyways and from my experence the way dom mods them (not mounts them as that is fine) is not the greatest. Better off putting set screws in instead of leaving the ball bearings.
Best way and simpelest I have seen yet is that used by rip. However I will not say how to do this as I am not sure if Jonno and Steve want everyone to know there way.

When you take the drill apart keep the chuck. When you have your wheels take the plastic part off the chuck and turn it down so that it will squeeze tightly into your wheel and then pin it.
Everyone does it differently it just the best way that you find to do it.
Glen thats an ok idea but the only problem is.
A drill with a chuck and torque ring weighs around 700g.
A drill without a chuck or a torque ring weighs around 400g.
Thats nearly half the weight. Only a surgestion but I say drop the chuck and maybe the torque ring but the torque ring can be handy if you want to allow some slippage.

he was refering to using only the metal part of the chuck, with some lathing you could use that piece as a hub, a very easy solution for the ones who do not have the right tap and its not super-heavy.
Nils you dont need a tap. Just use the thread on the drill. It works well and i would say I know atleast 5 people who do it that way.

You dont need a lathe to change those chucks into hubs. I attack then with an angle grinder and I removed about 80% of the weight from the chuck which then fits nicely in a scooter wheel. But I recently brought a 3/8 24 UNF tap so all my wheel problems are over.
Thanks for all advice, Ill se which way i choose.
