Anyone know how to glue plastic back to the same plastic?

The type of plastic is unknow.

What I'm trying to make solid again are the spokes to my lawn mower wheels. The wheels are $30. If gorrila glue will do it, that'd be a huge savings.

I tried using regular super glue, as well as gel super glue, it didn't adhere (set) at all.

Nearly every super glue has the notice that it will glue "some plastics," or "most plastics." Some say not for plastic.

I've yet to see any plastic that these glues will put back together.

I essentially need to "weld" the broken spokes back together. If you know of a glue or any other adhesive that will work, please let me know.

--oh, I did find one "super glue" that was for plastic. It "melted" the plastic so it would bond; then you were to apply the fix that made it set--only that part didn't work. The glue melted the plastic but no mixing it back to being hard. I was left with a worse, broken part, than if I had not applied the super glue for plastic. I had to throw the item out.

With the wheel at $30, if there is any way to save it, your suggestions will be very helpful.

Thanks
