mon-goose to MON-STER

Yeah that's the thing, I can only remember not to overtight from that post, maybe only my head messing with me now about the whole thing, sorry...

Don't feel bad, I don't remember stuff either, hell I forgot your phase wire upgrade you did. In the US, we call it CRSS, cant remember shit sometimes. :p
 
Allex, yeah I thought about the nut pulling the flat axle part away from the round part where it meets at he shoulder. That's exactly where it broke and with the lug nuts, its done up pretty tight.
I'm putting a deposit down on an axle today. Tench is quite prompt with his replies.
Hopefully I'll be back in business in a week or two.

Rix it was clamped on both sides but I couldn't clamp down the gear side enough with the flathead 5mm bolt. I have an Allen key nut in there now and I'm able to tighten it easily.
 
Unreliability gets on your nerves after a while.. I hope you can get it all sorted.

To be fair, a 3525 pulling 6kw will put out around 150 NM of torque at low speed according to the ebikes.ca calculator. That combined with regen is going to rock the axle back and forth with some serious torque!

Yes that's true. I've abused it a fair bit. That motor is on its third rim so that kinda shows how I smash it around.
No regen though on this last axle. The engineer I got to do my last axle has sleeves all ready to swap it out so hopefully I can go in there and get it changed while I wait. I'm thinking if he just pushes it in a can inject some jb weld or locktight after. Lock tight prior to pressing would be ideal. I'll need some more 5mm keyway steel to.
 
Burnt FETs?

I've connected the motor and found it runs rough starting from certain positions. I'm not getting a speed reading through the ca though. I'll open the controller and test the FETs soon. But I'm suspecting the short from blue phase to neg hall through the axle took out the positive blue fet group. That doesn'teexplain why no speed reading though. And yeah there is a 5v signal coming from the hall plug so the neg hall didn't burn out to open. I don't think this controller runs at all with out all halls fully operational.

So was it axle lash that broke your axle then?
 
pendragon8000 said:
Axle lash? Well I don't know about that. IMO it was all the load going through the weaker side if the axle and breaking it the spinning the unloaded axle side in the dropout and torque arm.

Axle lash is a term I coined. What I mean by it is if the the axle has twist play in the drop out, such as when under accleration, the axle snap rearward in the dropout until is stop against the flat of the dropout. That snapping motion can put a ton of stress on the axle. If there is another term for it, I don't know what it is.
 
Damn dude, again ?! I dont wanna jinx myself but I've never broken a single axle. And I'm not exactly toddling around with low power levels.
It must be your riding style. You're not that heavy but if you're doing in rims as well it sounds like you're asking a bit too much for bicycle spec equipment.

Given you've minced the wiring as well I reckon *waves hand* it might be time to upgrade to a H40

/jedi mind trick :p

Haha nice try. Probably not yet as I've got the new axle on the way. Anyway, h40 is heavyer with the same axle(different bearing positions)
So for my main issue that wouldn't really be an upgrade.
I am considering getting a raptor from you though. I'd like to buy a mig for aluminium and a small lathe then I could make a frame for the same price and have tools as well. Pedal clearance on the swing arm is the hardest thing to deal with IMO
. anyway with that I could go crazy and run 100amps in a tc-80 in 24" on 18s

I'm happy to hook you up, but going the DIY rough with frame construction is harder than it sounds. Modding an existing frame is pretty easy but there's a heap more work involved when you're building from the ground up. Hence why my own frame design is taking so long to get off the ground and why I've taken up the raptors in the mean time! I'd be a bit reserved about making a frame from Al your first time out too. Steel is more forgiving and even some of the fabricators I've spoken to while sussing out my own frame project have been a bit nervous about Aluminium.
 
Is hyena the raptor importer now?

Although I can imagine Pend riding a raptor, it just doesn't right. I have this image of Pend being the diy guy all the way to repairing a motor a thousand times for example. :lol:
mongoose to monser rather than complete build done for him...

again a raptor will not solve his problems of breaking stuff. Maybe cro?

yeah Bozi, thats it. i think this motor has had about 5 sets of halls(3 sets were wrong type), 2 thermostats, 3 axles (one was the wrong one - sigh) and 3 rims, 2 sets of spokes. shes a trooper. i figure as long as the coper and magnets are good and have the ability to fix whatever im just riping myself off to not fix it. and the ht3525 is light and slowest.

and yeah im a DIY guy for real. also with welding aluminum/aluminium, a mig on that is much easyer than arc on sheet steel, especially 1.5mm bike frame, i was loosing my shit when welding that and the neighbors knew all about it haha .

Yeah, but there's still plenty of customization you can do. I have some pretty big plans for my own one I'm building up now and admittedly some of them are a little juvenile :lol:

Fair enough. I'd be inclined to do as much of the work as possible myself then pay an experienced welder to neatly stitch it all up. But then your current bike hasn't fallen apart yet so what would I know :p

I'll send you a PM, I don't want hijack Ken's thread.

yeah pretty much

got a sheet of aluminium today 1800 x 800 ... new battery box for scott spark comming and starting work on the 6kw bmx for chopbusta... still waiting for him to jump in.

behind the painting and bike stuff.

Check out these beauties from Tench.
P1000899_zpsd501d091.jpg

Top one is for Chopbusta's BMX
Bottom one is for my monster. The axle is 19mm rather than standard 12mm.
I'llsort out the pPayPal invoice today and hopefully have this bike back on the road in a week or so.
I'm considering buying a press for the axles. They are available for $180 on special.
