I’m fascinated by large “Cuban link” styled curb chains and I was thinking of making my own but probably 5mm width and nothing too insane.
My question is about how they are filed flat after they are twisted. When I’ve seen videos of large curb chains being filed, the file is held with both hands (one on each hand) and actually used in a perpendicular direction to the length of the curb chain. How is that working? I’m asking because I wonder if special kinds of files are being used so that they can work in such a perpendicular position.
I know there are many different kinds of files like “lathe files” for example. But I never heard of a file that can work in the perpendicular position or nearly perpendicular.
Thanks for any info.
