Lab and Workshop Exercises
In the chemistry lab, students cut lengths of Glass Tubing for delivery tubes and bends. One firm stroke of the file edge leaves a short scratch across the tube. The tube is wrapped in a cloth, the thumbs press behind the scratch, and it snaps cleanly. The cut ends are then fire-polished in a burner flame. A Glass Tubing Cutter does the same job by scoring right round the tube.
In the fitting shop, the file cleans out the corners of a slot or square hole and trues up internal angles in a filing exercise. Students also restore a bruised thread on a bolt by filing along the thread groove. They then check the thread by running a die from a Tap & Die Set, Metric Small over it.
Frequently Asked Questions
How do I cut glass tubing with a triangular file?
Lay the tube on the bench and make one firm stroke across it with the file edge to leave a short scratch. Wrap the tube in a cloth, put both thumbs behind the scratch and push gently outward while pulling the ends apart. Fire-polish the sharp ends before use.
What angles can a triangular file reach?
Its faces meet at 60 degrees, so it files internal angles greater than 60 degrees and clears out square corners. For angles sharper than that, a knife file is used instead.
Can it repair a damaged bolt thread?
Yes, for bruised or burred threads. Hold the bolt in a vice, file lightly along the thread groove to remove the raised metal, and keep to the original thread angle. Test with a nut as you go. A badly damaged thread needs a die or a new bolt.
Does it come with a handle?
Yes. It is mounted on a hardwood handle for a firm grip, so it is ready for use at the bench or beside the glassware. Keep the handle tight on the tang and replace it if it splits.
