Workshop Practice: Filing a Flat Surface
The first fitting job in most ITI and polytechnic workshops is filing a mild steel block flat and square. Students clamp the block low in a Bench Vice, rough it down with the bastard file by cross filing, then change to the second cut. They hold the blade of an Engineers Square across the face against the light to find high spots, and check size with a Steel Rule.
Finishing is done with the smooth file, often by draw filing along the length of the work. Between grades the teeth are cleared with a Wire Brush For Cleaning Files, because metal packed in the teeth scratches the surface. A later task is filing an edge down to lines marked with a Single Ended Scriber.
Frequently Asked Questions
Why does a filed face come out rounded and not flat?
The file rocks when the pressure of the two hands stays the same through the stroke. Press more with the front hand at the start and more with the handle hand at the end, so the file stays level. Check the face against the light with a square after every few strokes.
Why are the three cuts different lengths?
For the same grade of cut, a longer file has coarser teeth and takes a longer stroke. In this set the bastard file is about 300 mm, the second cut about 250 mm and the smooth cut about 200 mm.
Do the files come with handles?
Yes, the set is supplied with handles. Never use a file without one, since the pointed tang can injure the palm. Seat a handle by tapping the handle end on the bench, not by hammering the file.
Can these files be used on hardened steel?
No. Files are for unhardened metals such as mild steel, brass, aluminium and cast iron. Hardened steel blunts the teeth quickly and is ground instead.
Should a new file be used on steel straight away?
It lasts longer if it is started on brass or bronze, or used with light pressure on steel for the first few jobs. The fresh tooth tips are thin and can break off under a heavy cut on hard metal. Keep files apart in a rack as well, so the teeth do not chip each other.
