What is the hub size and what is the hole size. May be a slice of pipe that meets the need. Is there any way or any place you could get it filled and drill it. Maybe put it on buy/sell/trade section. Good luck.

1 1/4 inch for hub and 1 3/8 for the sprocket

All right it might not be to hard to fix. It is only 1/8". find a piece of pipe with a 1/8 " thick wall and cut it a bit more than the thickness of the sprocket. Use it as a spacer. I would tack it in with JB Weld or such. Good luck.

I can tell you what I did.
I used the dust cap from the hub as a template. Drew a circle with a sharpie on the sprocket. Centered as close as my hands and eye could make it.
Clamped the sprocket down to my work bench and started making one cut after another from the existing sprocket hole out to the line I had drawn. I don't remember, actually, whether I used my jig saw or my sawzall. Probably sawzall since this is a fairly big job for a cheap jig saw.
Ended up with a hole that was "toothed". Ground and filed these teeth off with hand files and dremel tool until it fit over my hub.
It's probably not perfectly centered, but I can't tell any difference.

The hole in the sproket is to large as I understand it. Like maybe a coaster brake size hole going on a mountain bike hub.
I just use the dremel like you if there to small.

You just need to get it centered. You could whittle a piece of wood. The nuts and bolts keep it tight. So you could wrap a rubber strip around it to get it fairly centered. Then tap it into place.The key is get it centered. A good fit on hub helps to keep it from shifting up,down,back, and forth so the chain don't wobble off, curbs vibration and saves spokes. Use the bolts and nut to line sprocket so runs true. good luck.

Actually from what you write below it is the opposite to what you wrote at first. The hub is too big for the sprocket by 1/8". I get a similar problem with the big geared hubs and I bought a circular drill bit that I can drill the correct size hole with on a drill press. It's not that expensive and saves drilling lots of small holes and then grinding it something that looks circular. I hope your clamp brackets will fit over yhe spoke flange because I had to make large ones of those to go over the big Nexus geared hubs which are pretty huge.
