Making speargun. Please help

Welcome Sam. There is a lot of information to cover when it comes to building a gun.

Here's a good place to start:

سام خوش آمدید. مقدار زیادی از اطلاعات برای پوشش دادن به ساختمان تفنگ می آید وجود دارد.

در اینجا این است که یک جای خوب برای شروع:

I hope this is the correct translation.

How is the visibility where you plan to use the gun? How many meters?

What is your height?

If you have good visibility, then you can use a longer gun. Also at 1.73m you're not a short fellow, so you can load a longer gun. I recommend a 110cm - 120cm speargun, with two 16mm rubber bands.

Do you want to make the gun from wood?

For a wood gun you will need a trigger mechanism. Have you thought about buying a trigger mechanism or building one?

Saam, I believe you will have a hard time legally importing a trigger from the US, so that leaves you with fabricating your own. Without good materials and skill making one can be very dangerous. I do not profess to know you country's laws but is a speargun legal to have there?

I want to build myself pull the trigger. By Lathe. What kind of metal is the trigger?

Are spearguns legal to hunt with there?

Will you be making your own shafts too? The mechanism in your picture accepts a shaft with a round end. Is that what you want?

Quote from saam

What kind wood do I use? / Heavy or style? Name wood's?

I teak is available, it's the best choice. It's not necessary to coat the wood with a protective finish. Oiling is enough.

These are the trigger mechanisms most commonly used in speargun builds Speargun Trigger Mechanism.

They accept shafts that have a flat area in the back.

If you're going to be buying shafts, you need to make your trigger mechanism choice based on the shafts available at your location.

Which shafts are you going to use?

For the options (line release orientation, conventional or reverse, accepts mono or not), holding power, smooth trigger pull, overall quality, price, and the fact that spearguns are allowed in your country, I think it makes better sense to buy a ready trigger mechanism. Perhaps someone else will contribute with instructions on how to make a trigger mechanism. In the meanwhile you can take a look at Tufual's thread, he made his own mech http://spearfishing.world/spea…-pine-speargun-build.html
