Re: Best Railgun/Pipe gun handle

Being under or over gunned in the moment is part of spearing, some fish you have to let go by for another day. Blasting your shafts into rocks, either through a near miss or shooting clean through...

Re: Best Railgun/Pipe gun handle

I think durability questions are not that simple and one cannot make those sort of generalisations. If you want longer band stretch then just make a longer gun barrel. The main advantage of the...

Re: Trigger safeties: To have or not to have

One way to increase discrimination between safety "on" and "off" is to use a cam that presses up against the sear lever when cocked, but swings down out of the way when the safety is off. Here the...

Re: Trigger safeties: To have or not to have

Looks like the Ermes Sub Double Roller gets its safety installed in this grip mounted version for a eurogun layout with pistol grip and loading pad poking out the back. Getting your finger onto that...

Re: Best Railgun/Pipe gun handle

The Meandros pin roller is more like the roller tooth used in the old US Divers "Sea Hunter" spearguns, only there instead of a lever dropping down a sliding block was pulled out from under the...

Re: Best Railgun/Pipe gun handle

The difference is the Meandros roller tooth loads up the sear box walls and the force is thus reduced going down onto the sear lever, that doesn't happen in the Ermes Sub DR where the roller tooth...

Re: Best Railgun/Pipe gun handle

The standard trigger mechanism usually mounts the spear tail in a socket created by the sear box that wraps most of the shaft circumference except for the spacing created by the width of the levers....

Re: cracks on trigger area

I drill pin holes to size as at some time I may want to drive the pins out and I don't want the timber to crack. Once when dismantling a long-time favourite gun to my dismay one pin drove out taking...

Re: cracks on trigger area

The mechanism pin holes flank the pocket in the stock that holds the trigger mechanism. This is the weakest part of the gun if it is subjected to side loads during rough handling, such as the gun...

Re: Trigger Mechanism Design Rules

Note that there does not appear to be any cam locking of the levers here, the mechanism seems to rely on the force at the sear lever's lower tip, or retention step, not being great enough to roll the...

Re: Trigger Mechanism Design Rules

A few years back Sea Hornet Australia were developing a eurogun style speargun which was a first for them as previously their range consisted of cocking stock guns. Some of these guns had a very...

Re: Dano w/ MAKO Spearguns: on world records and pole spear resting hooks

What about ferrule joins in the spear as that is where I hang onto mine. I don’t care about records except to see how big some fish can get, but ultimately they are all heading for the frying pan or...

Re: Trigger Mechanism Design Rules

This second diagram shows how the "mobile" roller tooth can accommodate different diameter spears by riding up inside its cradle or cut-out in the sear lever arm to jam spear tails against the sear...

Re: Trigger Mechanism Design Rules

I have been asked for a full diagram of the Ermes Sub Double Roller mech so here is an approximation of it. The important part of this mechanism is the shape of the top of the trigger which has a...

Re: Long Pneumatic Guns

Possibly in the interests of improving vacuum seal life Salvimar have introduced a new spear tail with an angled collision face of 45 degrees. Right now they only come on the 7 mm and 7.5 mm shafts...

Re: Long Pneumatic Guns

If you buy a Vuoto and want to try the wet barrel equivalent it is relatively simple to swap the muzzle to the standard muzzle. There is no other difference in these guns. The wet barrel guns...

Re: Long Pneumatic Guns

Anything that is designed to be pressurised is always built with a safety factor so that varying operating conditions don’t impose a risk of the item blowing up. The safety factor is probably of the...

Re: Long Pneumatic Guns

Those grey tubular grip handles remind me of the extra fore grip that used to be added to the old Arbaletes such as the Champion later Beuchat "Canon" to drag the nose of the longer gun models around...

Re: Long Pneumatic Guns

Well it appears that Seaviews has the Mares "Sten" Pipin guns. The problem with the “Aqua Gear” guns is that initially they had flimsy grip handles as they went for that over moulded grip handle...

Re: Long Pneumatic Guns

Well if I were you I would go for the Pipin model as the chance to get one of those is a real opportunity. The Asso is actually a slight variation on the original Sten model with its finger grip...

Re: Long Pneumatic Guns

The very long guns also had a float and a folding knee loading handle, you can see one here.
