Attaching a sprocket to a shaft that is fat on both ends.
 
I am new to the forum. I am trying to attach a sprocket to a shaft that necks down in the middle. This is an unusual shaft on a snowmobile. Each end of the shaft is about 0.97" inch but the middle is about 0.90". Here is a video to help describe the shaft

Thank you for your help.

Snowmobile?! WRONG FORUM!
Nah, it's cool.
What do you mean by 'necks down the middle'?
Do you mean a keyway? FYI that would be a notch in the shaft.

Are you wanting to put a drive sprocket on the thinner part?

Ahh yamaha eh? You could cut the sprocket in half and weld it on...best bet would be to machine the shaft or use the original chaincase/sprockets.

Yeah. I would like to attach a sprocket to the thinner section. Where would I find a split sprocket hub and a sprocket to match?

Right about now, I miss that guy that used to post up these animated posts that had a cursor clicking on Google.

scroll down to the six spoke hub... looks to me it is a split hub
matching (coincientally) two piece split sprockets as can be found on that very same page ;)

you can find various two piece hubbed sprockets as well..
like
https://cometkartsales.com/50mm-Stee...428-Chain.html
(the first match on google so maybe not the size you need)

but searching for "split hub" should find you some

As always:
do NOT weld to an axle!

And yet it was animated. Maybe you meant "polite" . . . It was not polite. For that matter it was not helpful or obvious since I had already done a lot of googling.

Close, but his cursor would click on the Google search and pull up the answer, then he would say:"Was that so hard?"

Hmmm....Dave seems a bit high strung and pouty.
