Has anyone tried oil filling one of these? Looks doable and should massively improve heat shedding.

Re: railroad tracks then ER

Paracetamol = Tylenol, normal adult dosage 4x 1000mg daily.

Ponstan = not sure, maybe Ponstel? Ask the chemist for the anti-inflammatory Mefenamic Acid. Normal adult dosage 4x 500mg daily after meals.
Ponstan/Ponstel might be expensive in the USA. Fairly cheap elsewhere around the globe.

Re: My electric Volkswagen Sandrail (Dune Buggy).

The part I would find hardest is remembering that the electric motor is happiest at high RPM whereas ICE's generally are not. I would always be shifting into 3rd or 4th when cruising where it would be better left in 2nd.

It is likely the majority of new vehicles will be powered by other than fossil fuels in 8 years. I doubt fossil fuelled vehicles will ever completely vanish.

That's a lot of end float in the video of you moving the crank. Looks to me like the thrust bearing wasn't adjusted correctly to begin with. Now you have taken it apart, when you put it back together if you set the thrust bearing clearance correctly you might find the creaking disappears along with ...

Re: Bulk Ferrotec Ferrofluid APG1110

Of all the Ferrotec fluids the APG1110 or APG311 look most suitable to me. I can't see why you would need a carrier with higher flash point than 200c given (from anecdotal reports) most motors seem to fail around 150c. Also, the presence of the ferrofluid itself should lower the risk of in hub temps...

Re: Definitive Tests on the Heating and Cooling of Hub Motor

A very heavy layer of the red urethane on the windings either side of the stator could be the go. Keep spraying coats from the sides until it is filled. This would keep the ferrofluid or any other fluid out of the windings.

Re: new cyclone 3000 w mid-drive kit?

Dingus,
My apologies, upon reflection I think your solution is probably stronger, as in stiffer and less susceptible to deflection at high load.

I still think that Dogman's solution is the most elegant so far, in both meanings of the word.

Re: new cyclone 3000 w mid-drive kit?

I took Spinningmagnet's comment that Dogboy's braces are "correct" to mean that his calculations are correct and his solution is pretty neat. I agree. Dingus' assertion that the braces are not perfect and may be subject to distortion at the bends under extreme load is technically correct. However, g...

Re: Ebike light tap and switch

Your light powering up with a disconnected battery is either magic or regen. I am guessing regen.

With the switch, you cut the positive line to the light and connect one side of the cut wire to one of the wires from the switch, and the other side of the cut wire to the other wire from the switch.
