Thanks Bill,
I used JB weld and sanded them down. I learned that a file works quicker and even better if used prior to the JB weld completely setting.
I currently may need to re-do a few cracks because I noted that with significant pressure on the wheel the cracks open a fraction.

I am looking at redoing with a 2 part expoxy and re-sanding.

Thanks for the Eastwood links, I have currently moved onto other projects as I can not afford to buy any new products, parts or materials.

That is just the way it goes smile
