Travel tube gun idea for split spears

  • Usually travel spearguns have two piece spears that are of equal length, i.e. the shaft join is the center of the assembled spear, but that does not have to be the case. If the shaft can be made in unequal lengths then the bending at the join should be reduced. The shaft main body is sized to fit inside the barrel tube and the balance of shaft length, i.e. the tail, is taped to the main shaft for transport, all being packed inside the barrel tube. Rear handle and muzzle are removed and carried in your travel bag. If the spear tip unscrews then the spear can be resized to fit more shaft main body length in the barrel tube and hence the tail piece can be shortened.

  • Given the internal diameter of the barrel tube it should be possible to transport a couple of spears inside the tube, possibly three of them in the disassembled state. Spears being ammo you need at least two shafts on a trip, and ideally two guns. When you only have one gun and you lose it or the spear is bent you are going to have to source another weapon, not always an easy thing to do.

    Here is a version with a detachable spear tip.

    Watertight bulkheads can use "O" ring seals to be loop attached to the transverse screws and nuts that hold the gun end pieces on. This bulkhead method has been used in the past and the cord loops are used to pull the bulkheads out of the gun. Increasing pressure at depth cannot push the bulkheads in because they are restrained by the loops which are anchored on the screws.

  • Note so that you don't scratch the barrel tube bore it would be best to cover the ends of the shaft with a turn or two of vinyl tape, otherwise the bulkhead "O" ring may not seal the tube when you put the gun back together. A warning sticker on the barrel tube may be in order stating that the tube is heavy, especially if it has 3 spears nestled inside it making it virtually an iron bar, so don't pitch it should be the message to baggage handlers.

  • I've found that eventually, barrells without plugs will leak. The o'rings in the handle and muzzle are subject to forces that will make them leak. Taking off a plug from a barrell without destroying it is virtually impossible. So, better store the shafts aside the barrell when traveling.
