I did something similar except ran a rod all the way through.
I took a 1-1/4 inch coupler and sanded the inside down so the 1-1/4 inch PVC pipe would go all the way through. I also cut the coupler on one side so it would slide easier. Then ran a 5/16" threaded rod through the PVC pipe (M8 would be better but they didnt have one). Youll need some lube if you do it this way as its a tight fit, but the pipe hits the bottom and theres not any give so the grinder stays put the whole way around.
