1st build using sapele

For an enclosed track I prefer poured epoxy graphite or cut right into the wood.

I see you're here in Fort Lauderdale, you should check out the Speardiver trigger mechanisms Speargun Trigger Mechanism.

Enclosed track for a 36" gun? I don't think so...

For the rest, I leave it to the experts.

As a noob spears, I'll leave the gun stuff to the seasoned guys but As for the building aspect,that's all in my wheelhouse. Sapele is a joy to use, just pay close attention to the rising grain direction as it does have the tendency to tear out deep if it tears out.
Although there are different schools of thought, directly from the manufacturer, TB3 is waterproof but NOT recommended for being submerged for any length of time. I have seen tb3 fail under high humidity applications too many times to trust it in a lam blank. Ws epoxy is a great alternative.
Stain or oil before epoxy? Absolutely, you actually have to. Epoxy is there to form an impermeable film finish. If you try to oil or stain after, if will just sit on top of the epoxy and look like junk. If you use oil, make sure it has finished fully curing before final coating.

Marco, why do you say this? Is 36" too short to get any benefit from am enclosed track?

Yes, the short rod is already stiff enough for what your building,

To me an enclosed track is just about convenience, though there may be other benefits. So I'd do a short gun just as well.

Some very smart people in this thread giving you some great advice. My 5 cents, Don once told me that a open track is as good as enclosed, to my shame I was sceptical. I have since owned a open track bluewater gun, there was no difference in accuracy, range or recoil. My issue is my tracked guns load way faster and surer than the open, so no matter what size I like my wood guns closed track.

I shoot too many rocks thinking they are fish.;)

Shooting one is bad but at least you figure out what it is pretty quickly.
While h&l fishing the bottom once, I dragged a broken off piece of coral about the size of a kitchen sink at least 150 feet up thinking I had the world's record halibut on the line...

ALFONSO I hope you construct a good gun and good pieces Pesques :thumbsup2:

and forgive the intrusion in your posts, not knowing the language is a coñazo

Yes. The only benefit would be the ease of loading, but again, in such a short gun, I'm not quite suremthere is as the short shaft will be easy to insert into the mechanism. More if you build it with a deep open track.

You will have disadvantages though, as when shooting at short distances (that's what a 36" is for, right?), maybe you either hit a fish or a rock before the shaft leaves the gun, causing it to break.

Good to know.

You know my dirty water gun is a 120 with enclosed track. Not sure if I am lucky or John at Koah poured his tracks bulletproof, but plenty of time point blank at fish in holes, straight through fish and into rock or steel from a wreck. Bent some shafts doing stupid stuff like that but never had a dent in the track, not once. He opens up the front to accommodate movement if you supposedly shot a fish close. I hear about tracks shattering but in my experience with my Koahs not even close doing everything they said I should not with a closed track

Wow guys thanks for all the help! And yes dan ive been planing on coming out there just haven't had a chance too. Ive been doing my research on building a gun for about a month now an i see you guys have some good stuff for a good price.

I just bought two reverse mechs from there. I had a loose spring on one but by and large, the fit and finish is really good. Install was really easy, action is very smooth.

depends on how strong you are :laughing:
16mm band or 19mm band, 250% stretch or 300% stretch are better questions, but how strong are you?

Use sharp bits and blades. .
