I include some diagrams to illustrate the basic dimensions of the gun.

The handle diagram can be cut out and used as a template on the glued-up wood parts

I loaned the Southern speargun to a mate to get his impressions of it.
(He normally uses a Sea Hornet so the comparison is a bit unfair)

He said that on the positive side, the gun was a lot lighter to use in the water, and it had a lot better long distance range and accuracy.

On the negative side, he commented that he found that without the butt extension it was a bit harder to load. He also noted that the line clip needed adjstment to ensure that the shooting line stayed in place (easily fixed).

I'm still quite interested in making this gun one day. Cant spare the time or money for it at the moment though... Although it is always in the back of my mind.

If you have any problems, post them (In fact, post your progress if you don't have problems).

I sometimes don't get to the forum for a week or so, so if I don't reply, PM me and that will send me an email.

Ric

Spear guide recess

I received a PM asking about the recesses on the top of the stock.

When I designed the Southern Speargun, I wanted a gun that didn’t require fancy tools, or highly developed skills to construct.

If you have a router, its relatively easy to cut a channel or rail on the top of the stock, but if you don’t have a router, these become quite difficult to make. I decided to go for several spear guides that would be set into the top of the stock. The spear sits in grooves cut into the top of these guides.

To make sure that the guides are securely located in the stock, a recess, or pit, (or mortise) is cut into the top of the stock, and the bottom of the guides sits down in this recess. In the finished gun, the guides are not only held in place by glue, but are also kept there by the walls of the recess.

Cutting out a pit can require a bit of skill. To make the process simpler, parts of the recess are first cut out of the centre laminate. A square edged “U” shape is removed from the top of the stock. I did it by first using a saw to cut the forward and rear walls, then using a chisel or rasp to remove the wood in-between. Then I glued-on the side laminates for the stock, and these provided the side walls of the recess.

Once the glue had set, and the excess cleaned out, I had a rectangular shaped recess in the top of the stock, ready and waiting for the spear guide to be fitted in.

I have had some emails/pms asking about building a spear channel into the stock rather than using the spear guides I described above.

I designed this gun with guides as you can build it without having a router. But if you do have a router, a spear channel is probably better, and easier to load.

Basically, when you build the gun, you can use a hand held router to cut a spear channel down the centre of the stock. The channel extends between the shot engine (AKA trigger mechanism) and the muzzle. The spear sits in it. It stabilises the spear, making sighting and aiming more accurate, and it might reduce spear whip to some extent.

The spear needs to sit flat on the bottom of the channel, and also fit neatly into the shot engine. Fortunately, getting the correct levels for the two is not too complicated. You keep the top of the stock flat from where the shot engine is located to the muzzle. The shot engine sits in a mortise (hole) and has a flange near its top which determines how deep it is buried. I cut the spear channel between 3 and 4 millimetres deep, and about 7 mm wide.

If you follow these dimensions, the spear should sit nicely in the channel, and be a sliding fit into the shot engine.

To make the cut, I use a round ended 6 mm bit in the router, and adjust the fence so the bit sits just the tiniest amount to one side of centre, I rout the stock one way, then I take of the router, turn it around and rout the other side. To clean up the channel, I wrap a piece of sandpaper around a drill bit, and work this up and down the channel.

Sometimes, when you are in the water, it can get a bit fiddly fitting the spear into the shot engine, and getting the bridles engaging with the spear. This is especially true if you have thick gloves on. I find it a little easier to work the gun if I cut away a bit of wood for the 10 to 20 centimetres in front of the shot engine, cutting down to about 5 millimetres below the level of the top of the stock. This gives me extra room for my fingers
