I have just made a pump-drill for friction firelighting, made from items I found in a neighbours skip.
The drill is a length of wooden curtain rail, with a hole drilled in one end to allow the insertion of various wood-tips for firelighting. The flywheel is a round 2kg weight (the type used in weight lifting). It takes about 2 minutes to produce an ember but there is virtually no effort involved.
Now I am experimenting with making one from materials found “in the field”.
