If you could find a hubbed sprocket the right size you could always take off the hub on a lathe. McMaster doesn't have what you need. Maybe check MSC or Stock Drive Products.
<edit> you can get a 72 tooth hubless gokart sprocket but it's for #35 chain. </edit>
<edit2>I found a 70 tooth 1/4 pitch hubless sprocket here It could be a metric pitch so call and check but it looks like 1/4 pitch to me. I believe it is a half inch bore. I thought of it when I remembered my electric scooter sitting right behind me so I counted up the teeth and there you go. Not exactly 72 but heck you can get it and it's cheap. I'm not sure about the shipping. The company is in Orange County CA and you can actually go to them if you are persistent on the phone.</edit>
