Here is a simple sheet metal folder or brake that can be easily made at home with a few basic tools.
In general large files are relatively coarse.
Use a flat file for general purpose work a square file for enlarging rectangular holes and a round file for enlarging round holes.
To bend sheet metal in a vice start by marking a line on the metal where you want to bend it.
Next put your wooden or metal form blocks in the vice and clamp your sheet of metal between the forms.
