Here is a video i made of myself making a cone and 2 discs. It shows a few tricks that i have learned along the way. It may be a little boring to watch since it progresses mostly at real time as i make the cone all the way through the polishing process. youtube limits a video to 10 minutes and this is 40 minutes, so it is broken up into 4 parts. the first part had a song playing on the radio in the background and youtube was deleting the audio after i uploaded it, so had to transpose the audio track in order to fool their software. it sounds a little weird, but the other 3 parts have normal audio.
