does your setup include an idler pulley if yes 14t should be fine(i have used that) if not then let someone else answer as im not sure

I will have the dickyho mount so I can buy an idler too. Though I really don’t know which size of belt I should get with an idler. Without it I would buy either 345 or 350mm length. More like 350.

Halbj613 · January 3, 2021, 4:44pm

so when it comes you can use a piece of string to calculate by wrapping it around the setup

with an idler 14t should be fine i think

b264 · January 3, 2021, 4:46pm

If you follow the tooltips when you hover over Efficiency then it should be in the general area.

It’s at full charge.

This is going to depend on lots of things, though.

Thanks! The thing is I cannot wait for the setup and buy belts after. Belts here are like 10€ each and belts from dickyho are 2$.

@b264 Does 14T often skip? (talking single drive here)

b264 · January 3, 2021, 4:49pm

Skipping is determined by a lot more than that. I wouldn’t use 14T on a single motor setup. It’s better on a dual.

Avoiding belt slip

check the alignment very carefully. A belt that’s not aligned well can slip, as @taz mentioned.

Something else that can cause anywhere from minor to massive slipping in a perfectly aligned and tensioned belt, is broken cords. If your belt has broken cords inside, you will typically not see any indication of this by inspecting it (sometimes you can though) but it will just skip like crazy. In that case, failure is imminent anyway and you need to replace it before many more rides. If you check multiple belts, some new, and the skipping persists…

Then check when the skipping is happening. If the worst skipping is happening any other time besides during hard braking, then I don’t know what’s going on. That’s always when the worst skipping happens.

Alignment – the best way I’ve found to perfectly align belts is

get motor mount (without motor) snug on hanger, then loosen a tiny bit so it moves

install wheel and pulley with no speedring (washer) between the hanger and inner bearing.

push motor mount flush up against wheel pulley so they are touching each other

keep those held tightly together while you tighten motor mount clamps

make sure mount is flush against, and touching, the wheel pulley, and there is no gap or misalignment

finish tightening mount clamp all the way

make sure again that mount is flush against, and touching, the wheel pulley, and there is no gap or misalignment

when you’re all done, take the wheel and pulley back off, add a single 1mm speedring (washer) and just like that, the pulley will be perfectly aligned and 1mm away from the motor mount plate

if you need it further away when you are doing tensioning, then add more washers

And also make sure your pulleys are concentric and don’t wobble at all as @taz mentioned. That’s super important.

Okay, thanks! I will go 15T then!

Halbj613 · January 3, 2021, 5:24pm

how can i use standard trucks on a flux motion deck
got angled baseplates but will that work?
or do i need angled risers

b264 · January 3, 2021, 5:33pm

I don’t think “how” is the appropriate question. In DIY, anything can be done.

I think a better question is “why”. Certainly there may be a better deck choice out there for longboard trucks.

Halbj613 · January 3, 2021, 5:35pm

need a deck with huge battery underboard for 4wd longboard trucks and i love really large decks
the flux really appeals to me

the only other option i can think of is the evo but not a major fan of its shape

want a deck with a huge battery but also fast

Halbj613 · January 3, 2021, 5:35pm

other then 3dservisas very expensive option how else could i do it

b264 · January 3, 2021, 5:36pm

You could make DIY angled risers with some steel and a welder.

Halbj613 · January 3, 2021, 5:37pm

i dont have a welder so thats a bit of an issue

is there an stl for a riser like 3d servisas so i could print it

b264 · January 3, 2021, 5:38pm

I would not go down that route.

Halbj613 · January 3, 2021, 5:38pm

k
but why is that?

also do you know the angle of the flux deck?

PixelatedPolyeurthan · January 3, 2021, 5:39pm

3d printed part on a high stress area is just stupid, it’ll fail

Halbj613 · January 3, 2021, 5:40pm

oh didnt realise that was a high stress area since a lot of standard risers are softer materials

PixelatedPolyeurthan · January 3, 2021, 5:42pm

There was a Lacroix with hypertrucks… The guy put soft rubber risers. Guess what? Well with vibrations the rubber compressed, the titanium screws loosened and they snapped mid ride.

That’s what vibrations can do

Halbj613 · January 3, 2021, 5:43pm

ah k thanks
will probably go 3d servisas

last thing is will this deck be fine for high speeds just all fast boards ive seen before (40mph+) have used flat decks mostly

Cyanoacrylate · January 3, 2021, 5:46pm

Should loctite be used on the bolts attaching a motor to a geardrive?

If so what kind?
