although it's not pretty I made one by using a PVC union fitting and the spinner from a model airplane. I used a 1 1/4 inch union and a 1 1/2 inch spinner. I used some acrylic that I cut to hold the spinner about 1/2 inch away from the union. I also used the acrylic to take up the difference between the powerhead outlet and the inside of the 1 1/4 in Union. I'll try to take some pictures in the next day or two.
