Here you go buddy..... Look down and you will see 24 tooth with 3/4" keyed bore. $17!! http://www.usabearingsandbelts.com/18m7/sprockets/40-sprockets/finished-bore-sprockets.html

420 should be same as a 41, I think..... You're using a #40/41? Let me see.....

That's it according to guidelines #40,#41 sprockets go with a 420 chain (12.7mm) pitch. 428 chain have the same pitch but they are wider...so don't know if there universal.

Thanks jim. Really appreciate it. I'll defo have a look into that. I'm gonna use stainless for the shaft. And get some normal n6000 bearings. I've got a 14 tooth 420 sprocket for £3.50 FREE DELIVERY!!! Its a driver off of a pit bike.

WHOA!!!!off a pit bike? Is it a splined sprocket or a keyed hub?

 

[davidbooth1991]

From a pit bike and its splined to suit the driver.. But for that price I don't mind boring a circular hole in...also my boss has got a CNC gear cutter. He says it can make a sprocket...
But it always being used. He can make me one for free but I need to book the machine a month in advance...

healing up nicely......

So its been about Two and half weeks
Five x rays, five trips to hospital, a week off work, three physio sessions, a snapped index finger and knuckle, broken middle finger. Some abrasions and one long headache....apart from I think I'm ok....its healing up ok..and yes my new finger is about as strate as one of fabromans boomerangs and it will stay that way.( sorry fabroman you the only Aussie I know dude)...

 

[Poboy kartman]

Hmmmm.....as part of your rehabilitation.....I would suggest martial arts training. .....I think that middle finger may get you in trouble. ..

It sucks how fast things can go south.....and then you really appreciate what you DON'T have......

Yh I know man its a mess. I did actually do thai boxing (mauy Thai) for a bit when i was 15- 17 bit I won't be able to fall over with out this finger breaking again..... I've got to watch it.....but if we don't make mistakes well never learn from them.. Still hurts like a stitch though..the only rehabilitation I needed was THIRST aid..

[davidbooth1991]

I'm just gonna see if I can burn a 65t 420 sprocket on the CNC plasma we have loads of 6mm scrap.....it might just work and it will be tempered lmao....

 

[davidbooth1991]

Has it been done before by anyones knowledge ????

 

[davidbooth1991]

So I've got two weeks off work. Going away next week....
On my last day one of the lads gave me a push in the kart to test the steering in the yard...
I wasn't too happy with the live axle and really considering going driven wheel.. The steering is Affected by the live axle. ( no differential ).

Which I new would happen but I just think it may be better with the solid spindle axles...

What do you guys think. I need to sort this before I can put my brakes and sprocket on
Cheers boys...

 

[OzFab]

Now, how did I know that was gonna happen

You have a few choices:
1. One drive wheel on the axle, keyed to the axle & one free wheel with bearings
2. Split the axle; this will require twice the hardware but, will give you a bit of variation
3. Improve the steering geometry
