I have just recently built a simple design combustion golf ball cannon mostly of ABS material. While the combustion chamber consists of 4 inch ABS pipe, the barrel consists of a 1-1/2 inch CL200 PVC pipe which is similar SDR21 pipe. I sleeved the SDR21 with 2 inch ABS for additional safety. I needed to wrap the SDR21 with several layers of think construction paper to fill the gap. The golf ball fits this pipe perfectly leaving just a small gap. Luckily for me, the tapered end of the barrel and excess cement glue prevents the golf ball from entered the chamber. The issue that I am facing is that the barrel must always be in an incline when loading the chamber and aiming or the golf ball slides out. I have seen others using toilet paper or some sort of paper cradle which prevents the ball from sliding out but looking for other options or suggestions. I have attached a picture of the cannon as reference.

Thanks
