Not that much. 
I still waiting on the EDM machine but I have hope that I can use it in de next 2 weeks.
I also made a stupid mistake by trusting that the outer diameter of the motors where the same (there was 0.15mm different). Therefore, I need to make some parts for the second time.
Enough of the negativity. I made some parts, pictures 
One part I made again, this time 0.15mm smaller so now it is perfect.
I also made the first trunk axle. It is almost finished.
I can’t wait do drive it 
Love this rite here
That’s looking great!
Are those rubber sealed bearings?
yes all the bearings I use are 2rs. So rubber sealed.
Do you think there’ll be any issues with the seals having more resistance than shields?
99% of skate and longboards i see are rubber sealed (RS). So i say no problem. Less dirt but a very bit more friction the choice is yours
The extra resistance of a rubber seal bearing vs a steel shielded bearing is not that much, but the sealing is a lot better. The steel sealing doesn’t protect the bearing from sand and other small things. Therefor the bearing will be damaged a lot faster and the resistance will be a lot higher.
@nordle I saw your original post. A friend of my made a hub motor but he has problems at low speeds(bad breaking/acceleration), so a reduction is necessary if you ask me. The problem was that I like hub motors because you cannot see that it is electric. So there it was a hub motor with reduction.
Another thing that I like is building something unique and off course the challenge of building it.
Not necesary i think if you take low kv 50 to 100 i can calculate speeds around 30-40km/h for longboard sized wheels. That is what our belt friends mostly aim for. Really nice work however, i always like to see new exciting builds!
I believe the typical skate bearings use non contact rubber seals, not the contact rubber seals like these ones pictured
I can’t see enough for that from the picture
@TSG_AU @Nordle this are standard ball bearings, not low friction or non-contact seal bearings. But it is an electric skateboard so I can deal with the extra friction.
UPDATEEE 
The last couple of days I had some time to do some lathe and ADM work. First, I made a gear profile in the motor “hub”. After that, I made the gear the right length end internal dimensions. I also changed the sensors for the motor. Thereby I was able to lower the sensor PCB by 1 mm. just enough to fit everything in the wheel assembly.
Thereby the first part of the assembly is now finished. I have all the internal parts of the hub motor.
Time for picatures
so the motor made its first spin 
Amazing work man! Great job and can you post a video when its finished?
Of course I am going to do that.
So silent, top notch work
