I've been diving for 20 years and owned many spearguns, only used a safety on my first gun, haven't used one since as I prefer to practice safe diving than to rely on a safety that might fail... also, everyone knows what it feels like to line up a fish, squeeze the trigger and nothing happens 😂 But yes... This mech can have a safety installed got this who use them. Thanks for watching

Cheers

Koah Euro mech

Thanks Bob, it was very tempting to leave it out and hide it so I could pretend I'm perfect 😂 but these things DO happen and I've certainly learned a lot from others sharing their mistakes, glad it was a good reminder for you. Cheers

@@arcdesigns7066 it’s not about making mistakes, it’s about being able to fix them right? Hahaha thanks again.

Thanks, the plans were specific to the hardware I chose to use, best off deciding what hardware (trigger mech, shaft, etc) then design your gun accordingly.

@@andrewcoates5438 thanks!

@@mikeunleashed1 actually it's a neptonics Euro mech, the Koah is slightly different, but both are good

I used a clear marine-grade epoxy, the kind of stuff boat builders use. No problems, no movements, still perfect joints with no signs of delamination. cheers

Thanks, yeh it ended up getting a great alternative to abalone shell

Hi there, it depends on the diameter of the spear shaft you intend to use, and what trigger mech the shaft will lock into, but from memory I think I set the router cutter to half the depth of the spear shaft.

Hi there, I don't use a safety switch, so can't help you there. Personally I find it much safer to treat every loaded gun as "unsafe". Not only does this mean I won't line up a fish and miss the shot because the safety is still on, but I will hopefully behave much safer knowing it's ready to fire and not being lazy relying on a safety switch that may or may not be working correctly. Meanwhile, the manufacturer of the trigger mech should have guides available on their websites.

As long as the overall thickness suits your requirements, yes. However, 4 is better, but I wouldn’t use less than 3

@@andrewcoates5438 it 3 mahogany laminations at half inch. My dimensions are 1 5/8 x 1 3/8. Is that OK?

thank you

The weight of the spear shaft will hold the gun neutrally boyant in the water, if it still floats too much you can add extra weight to the barrel by drilling holes and filling them with lead, or you can increase the diameter of your spear shaft which will add more weight. If it sinks, you may need to add buoyancy tabs/wings to the fin stock. This one ended up being pretty spot on, it floated slightly so I've put a bigger spear shaft in and now it's neutral.

Does tilt forward slowly in the water or sits horizontal? I was told it needs to tilt slowly forward for trigger pull

​@@garrywagener4358 Not sure what you mean by tilt forward though, sorry, but ideally you want your gun to sit fairly flat (neutrally buoyant) so when you extend your arm under water you don't have to fight to hold it in place. Cheers

Thanks

Totally depends on your design, you can have various length guns, however, you want enough thickness to ensure your gun stock cannot bend or twist under load

Got it from a ship builder

Thank you
