sHFI 45deg punch on Tenka.
(It’s much easier to pop the front end on Xenith)
all i hear is belt skippage
10T motor pulley on HTD5M is no good
I personally would prefer 15T but in a pinch you could go down to 14T
I personally wouldn’t do 14T
Making the wheel pulley bigger and/or using the biggest wheel pulley you can is almost always better
These things also matter more on 1WD than on 2WD, which matters more than 4WD
@b264 Gotcha.
Do different pulley widths have the same minimum flex diameter (tooth counts)?
So for example would a 10mm belt have the same minimum that a 15mm belt does? (And would the same minimum hold true for 20mm belts?)
@yoyotinker this is a good question. @Shadowfax’s calculator shows a handful of builds running 8,9,10 or 11T motor pulleys.
Are all these 10T builds running wider hardware?
I did 12T for a while and it was pretty miserable, I think it was at about half that torque as well. 14 ain’t too bad I think
I haven’t double checked all of them but I think most of the small number pulleys are either gear drive or chain, both are metal to metal so they have a much higher torque tolerance. The first two (hercaleez and space Invader at 11 and 9 respectively) are definitely gear drives
I’ve used 12/32T and 15mm belts but with smol wheels. Was fine in my case (76mm wheels) but I can definitely imagine they would start getting skippy if you upped the wheel/wheel pulley size
I prefer 15T also but mostly because I prefer D shaped pulleys. Maybe going 15/48 would be be nice round setup.
And maybe 12/48 might be possible?
Those are for geardrives, not belts. If you want more torque, dump the tenka.
These likely are not belt builds. Stooge race team uses 10t and 11t pinions.
Some are also likely placeholders. Like, I plan to use a 4.5 gear ratio so I plug in 10 / 45
Correct - I am using 55/11 gears on Hercaleez. I would assume just about all motor teeth under 14 would be gears instead of belt pulleys
This is all good to know! Saves much time experimenting. Does anyone know the highest T count for kegel pulleys?
Or street boards in general? Maybe custom made sizes.
