Back in the 80's I build a squib rod, actually 2, one for 38's and one for 45's. Brass rods and attached a large round wooden knob. Make sure the rod is longer than the barrel it is intended for. It has been used maybe 4-5 times over that 40 years. Always put a couple drops of oil or Kroil down the bore and let soak a hour or so before banging it out if you have the option.
