Blacksmithing Project - How To Hand Cut Files 2. This video is a brief explanation of the information contained in the following references submitted by viewers of this channel - Thank you. Comments and links submitted by viewers. Alexander Hitman A few comments: From talking to historical smiths like those at Williamsburg, the technique for making the teeth was to lift and drop a hammer on the chisel, which is more consistent than striking and produced an even tooth depth (which means a longer lasting file). Another comment is that medieval steels could get reasonably hard, and the smiths clearly had some way of testing general hardness even if they didn't know why some bits of steel were harder than others. Also, I think you'd have better results with some kind of plain carbon steel such as 1095, or a low-chromium tool steel eg W1. Higher chromium content means more difficulty for cold work. If you work exclusively with scrap, I understand, but 3 feet of 1/2" drill rod is usually between $10 - $13 so well worth it in my opinion. DownyBill I've seen a video of an oldster showing how he was taught to do this when he was an apprentice in Sheffield England. The main difference between what he did and what you are doing is the order in which he struck the teeth. You form a tooth with the cutting edge facing toward you. Then you move the chisel towards yourself and form another tooth. -- What he did is place the chisel behind the raised ridge of the cutting tooth and use that ridge to position the chisel for the next strike. So successive teeth were further away from him. That made his tooth spacing closer and more uniform than yours. Brian Neeley This is an awesome dip into experimental anthropology. From what little I have been able to find on file making, I think Shane K is correct about cutting the teeth from tip to handle. I think the videos DownyBill referred to are    • The Process of Making a File   and    • Making Files by Hand   . I have also found one other video (   • How to make a Thin File Out of a Feel...  ) about cutting a file from a feeler gauge. The chisel he uses looks fairly similar to what few pictures I have seen for file making chisels. Somewhere I heard or read that some people didn't want to use early machine-made files & rasps, because they were too uniform. Without the minuscule variations of a hand-made file, you would supposedly get chatter because all the teeth were exactly the same height and distance apart. Something about the machine-made files producing harmonics. Probably not how I heard it described, but that is the gist of what I remember. Attila Hullman Nice video from a german file maker ,it shows the different procedures of work .    • Видео   TeknoXL Here's a link to help you out on making files. https://www.hrionline.ac.uk/matshef/u... From my research, apprentices started on round files to learn the craft. Also, when cutting the teeth, you start on the far-side of the file and cut teeth towards you. You use the raised section of the previous tooth to index your next tooth. The chisel used had a slightly rounded edge instead of a sharp one as typical of cold chisels. A YouTube video of someone cutting a file. It was very hard to find.    • Filecutting   LoneWolfsVoice    • Filecutting   this video and the one I will post after it are must watches on the topic. I know this is just an experiment video but I think these two videos will greatly help this project if you have not come across them already.    • Making Files by Hand   This is the second video. they are both useful. the thing that sticks out to me the most is the fact that the cutting edge of the chisel is angled back towards the cutter and the cutter works back towards oneself. I can only assume this is so the chisel can slide against the back of the previous tooth giving the cutter a way to feel out each tooth rather than going completely by eye.
