The rod holder is fastened from a 1" pipe flange base mouthed on a piece of plywood for stability. A PVC pipe adaptor is screwed in and PVC pipe goes up to an elbow with a short length of PVC with a ¼" vertical hole near the end. The rod I used was a quarter inch hard wood dowel pointed with a pencil sharpener.
For small props you can use 15 degrees, but then multiply by 24.
