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.

Re: Travel tube gun idea for split spears

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.

Re: Travel tube gun idea for split spears

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.

Re: Travel tube gun idea for split spears

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.

Re: Travel tube gun idea for split spears

I wouldn't want to trust a multi-part shaft on a multi-thousand dollar cross seas trip. I've heard some horror stories with the Riffe travel gun shafts bending like a pretzel on small fish. I'll pass, it's not hard to travel with 65" threaded shafts.

If there was no market for travel guns then no one would be making them, but the evidence is to the contrary.

I don't intend making any guns like this, the idea is simply up for discussion, plus I already have two travel guns and have not bent the spears yet, but then I don't use them very often. JBL made a two-piece spear as well as the one supplied with their “Travel Magnum”, it had a short tail of 316 stainless steel at 3/8” diameter and the front section was spring stainless steel at 5/16” diameter. Not sold as a travel gun spear, it still showed that a two-piece spear is a workable proposition and the step in diameter made for a line slide stop.

Depending on were your going for instance I travel to the Philippines every year and if I took a 65" shaft it would cost me $450.00 dollars for a oversize piece of luggage so for that price I could buy three to four break down shafts instead. I now travel with 59' shafts for my pathos roller gun and it cost me $150.00 cause it is at the 62" requirement but is an extra piece of luggage.

Re: Travel tube gun idea for split spears

Alemanni make a Travel Gun with two-piece spears, so I would think that they know what they are doing.

Yes it's robbery. Philippine Airlines only allow two 50lb pieces of luggage. I'm taking shafts next year so I'm going to see if I can take one luggage and one PVC tube and try to avoid the $150.00 charge for oversize luggage. Also they have a 62" max size limit anything over that is considered oversize.
