Homemade Hacksaw Frame Cut from Hard Wood (Boy Mechanic, 1915)
A hacksaw frame sawn from one piece of hard wood: the blade is bolted into a slot at the handle end and tensioned at the far end by a bolt with a bent sheet-metal head whose tongue sits in a saw cut so the blade cannot twist.

Bend a sheet-metal head onto a bolt (A in the figure) and fix the blade's other end to it. Pass the bolt through the far end of the frame and tighten its nut to draw the blade taut. A projection of the sheet metal fits a saw cut in the frame so the blade cannot turn.
