So im trying to make some rokkits but i cant seem to make the rounded part. I have plenty of tube to make the rest of the body but i just dont have a reliable way to make it. Does anyone know how to make at least a good tip? I tried takeing some sprue and gluing it together then running it through a pencil sharpener. I have also tried putting the sprue in a dremel and then running it on sandpaper also. Any ideas?
