Hello everyone! So my Dm asked me to make a train for him, and I jumped for joy to try it out. Especially when I got this this nice thick cardboard tube from work that would be perfect for the sides. But now im at a point that im stuck. I can't cut windows out easily while using my rotatory tool. I just get smoke and burning smells. Does anyone have any ideas how to go about it?
