trigger mechanism with safety

[nigelr]

Hi all.
I'm building some timber reef guns, max power will be 2 x 5/8" bands.
There a number of mechs available, but most seem to be devoid of a safety mechanism.
I'm resolute in my desire for a safety, at the very least to eliminate the possibility mis-fire during loading of the second band, which unfortunately does not appear to be as rare an occurance as we all would like...........
So to those that both have and continue to build guns, what could you recommend from your experience?
I will be most likely looking to the Kitto M4 for larger, higher-powered guns, just need a quality mech for 2 x 5/8".
Cheers.

you could fit a safety on any trigger mech, just drill a hole behind the trigger and fit a steel pin . personally, i dont believe in safeties. they just screw up my shots plus give a false sense of safety. you are never safe with tight bands. besides it takes like 8 lbs of pressure to activate a trigger under pressure. not really likely to happen accidently. but you CAN retro fit a safety. most high end guns dont have them. sea sniper, wong,andre,alexander, all have none.

safety ???? what safetyblackeye:blackeye

the safety is there merely to prevent the accidental push of the trigger ...but a trigger guard does exactly that...there is no way that the trigger will be accidentally pulled back...my finger is never there, unless to release the spear (hopefully) in a fish !!!

there are many more variables that would case the spear to go flying (even without the trigger being pulled) :vangry:vangry:vangry

i NEVER rely on safety buttons...i think if you want to be safe you just act and behave safely...safety buttons 'promote' accidents in my point of view (i might be wrong :t) !!!

safety mech or not , u have to act with caution and safety when handling a speargun !!!!

Thank you gentlemen for your kind replies. I totally agree with what you are saying in regards to safe behaviour with a loaded speargun, however my desire for a safety mechanism is very much more concerned with preventing mis-fire during loading of a second band.

hi,

i understand your wish for a trigger safety mech, but what i dont understand is why would the gun 'misfire' when you load the second band ???

if you are worried because the trigger lever will be pulled by mistake, then i dont think so....last time i checked, we have two arms-hand :t and BOTH are needed to pull the rubber back...whats going to pull the trigger back ??? (sorry for the bad humor :blackeye )


in case you are worried that the trigger mech will not be strong enough to hold the spear when the second band is applied and it will 'misfire' then surely you must obtain a decent trigger mech that will handle the amount of power you want it to....


P.S do you mean that if the trigger mech has the tendency to misifre by overpower (the trigger lever will be moved back by the force of the spear-holding-lever) and you want a safety-stop so that it keeps the trigger lever in place so it doesnt move and keep the spear-holding lever and spear in place ????


im confused

I think you are misunderstanding how a speargun safety works. All the safety does is stop the trigger being pulled.
If a gun fires whilst a second band is being loaded it is because the spear was not properly seated in the mechanism, or the mechanism is overloaded. A safety will not stop this in most cases, and if it does, the gun will probably fire when the safety is pushed off

Thanks for your replies gserghiou and dave.
We have 2 domestic triggers here in Australia, both use a functional safety mechanism. One is the Sea Hornet, the other the Undersee.
Consistant use of 2 x 5/8" bands is IMHO pushing the limits too much for the SeaHornet, which although it is a cheap mechanism, works admirably well within its' parameters, ie up to 1 x 20mm band, or 2 x 9/16" bands.
The Undersee handles 2 x 5/8", but I'm thinking I will go Neptonics, better construction quality for the price, albeit without a safety.
As you say dave, if the spear is engaged correctly, I'd feel confident of the Neptonics cartridge given the excellent build quality.
I'm not overly impressed with Undersee, although many have used it (including myself) over many years with success, its' design has certainly been improved upon over the years.
Cheers and thanks for your input.

Andre Mechs are avaiable domestically for you aswell and they will more than handle any power required, not to mention a local importer which makes any warranty issues alot easier, as for safety i recall seeing riffes guns had a key like set up for the back of the mech or you could try and get a hold of a Riffe euro mech with built in safety and lever.

[nigelr]

Thanks for that DD, never knew those mechs were available in Aus.
I'll have a google hunt for them.
Cheers.
PS, just tried the above without success, plenty of guns advertised but no mechs.

 

[DivingDane]

Andre mechs are definetly available here just have to order one through your local spearing store that deals with Andre PM me where you are based or post it her and i let you know of a store near you that you can get one from, just remember not to forget your local stores the net aint the only place to get stuff from.
