Im sure somewhere close to you should be a maschine shop that could do this for you for very little $ on a proper lathe
Easier to pay 50$ than to build a lathe haha
as much as I know there are far superior ways to reach the end goal of having many wheel hubs, ie all the ones I would want are available online already. Reaching the goal by making a small CNC machine that makes wheel hubs is an attractive option. Makes a lot of other things like in particular parts for the slip ring on the leiftech/SBX.
ah well shit the machine shop could make those parts too. Well I’ll be damned.
I mean if your planning on using it more than once or twice, it may be worth it for the fun of diy
I keep liking diy less and less and just want finished products from the start as college takes up all my time and energy
Finally got the rims finished for three other corners so I can probably go for a test ride tomorrow to see how they feel.
Comparison between the 8" and 10" wheels
Note, the wheel pulleys on the 10" are 70T and the ones on the 8" are 68T. Check the height from the bottom of the pulley to the floor.
Well I’m back from the first test ride and didn’t die, nor did I have to pull my wagon home, so a success I suppose.
Couple notable ride feel related changes.

Cons:
Man the torque is down, but this was to be expected, the pulley ratio + wheel size increase does reduce the mechanical advantage, so there’s just less torqyness(?) from that, but I also feel that the bigger+heavier wheels added with the bigger+heavier rims have added a lot more tire inertia, so it takes more torque to get and stop those things rotating. Otherwise carving felt still good and not too tippy. -
Pros
Maaaaaan is it smooth though. I even did a bit of off-roading and all the roughness I had compared to the 8" were just gone, especially when hitting the larger stone sized gravel. Very happy on that end. Tarmac was basically silk.
I didn’t do a good run to get a good comparison for efficiency, but I think the afternoon ride will be better for that. I’ll present some numbers on the results between the 8" and 10" setups. I think this setup is much more of a GT (grand tour) suitable, just due to the smoothness, but I want to test the efficiency, as I’m interested if my hypothesis about the motor loading holds water in practice.
Couple mechanical notes.
rear-left motor axle’s tip very slightly rubs on the tire
Slightly tightened the front truck in the middle of the drive just to get the feel a bit more damped at speed. Need to do the same thing to the back… but otherwise I didn’t really have any notable tire vibration/resonance issues, although I did only go max 38km/h (~22mph) downhill and ~36km/h on flat, so I didn’t push past 40km/h yet, but plan on doing so later this day.
Where you located man? If you’re in the US, I’d like to gift you some top quality filament to monkey with. Either my favorite PLA+ (which should give you better performance without any increased print difficulty), or some PLA-CF, PETG-CF, ABS-CF whatever you feel like monkeying with, just to encourage you to continue playing and reward you for sharing.
Shoot me a PM if you’re game.
can confirm PLA+ is pretty badass just add fiberglass
bam
The specs for Kegel cores… we need em linked here.
@SimosMCmuffin what’s the verdict on these 10x2.5 tires. You still like them? Wheels holding up?
What size is the rim for the ten inch tyres pls?
How did they hold up?
@SimosMCmuffin can you change the title a little?
I made that other thread to cover possibly non pneumatic wheels with printed parts.
oh I would just add wheel and hub as in my search there this thread is missing.
Seems to like keywords in title much more than that keyword in replies.

Can you find it now?
How did they hold up?
Still going strong.

10 inch rims, 6001 bearing:
@SimosMCmuffin what’s the verdict on these 10x2.5 tires. You still like them? Wheels holding up?
The tires are fine, a little bit un-optimal for esk8ing due to them having a very round profile, which is more suited for scooter use, as the whole platform leans when turning/cornering, whereas in esk8ing the wheels stay perpendicular to the ground, unless you’re using some tricked out trucks. So they wear out the tire first right in the middle of the thread.
So youre saying use pla at 100% infill? Did you try ABS with lower infill to go lighter? Do you know what % it could be reduced by pls? Great work
How did u finish the rims? Sanded n painted? Thx
