It takes a lot more epoxy then u would think. On my 58" roller gun it took 23 pumps of west coast 209 and resin and I still could have put in 2-3 more pumps do to shrinkage.

Well as the title states I making another roller gun, but this time it's going to be a 62-63" single roller. From everything I've been reading and from personal experience 62" is about as large as I can physically load. Saying that this gun will be shooting a 9/32-5/16" shaft and unlike my previous build it will be an open truck gun.
Let the fun begin.

You guys are going to love my next a guns lays outs. Designing some inverted rollers going into a demultiplying pulley rig. Simplier to the hatch yacht gun, but with some south Florida flare.

I choose that shaft simply for punching power and momentum. Not to mention Do to the shorter length of a roller guns shaft thicker diameters help keep the shafts weight up.

Well after 6 months of hard work I am finally done with my first very speargun. The block was laminated using west coast systems Epoxy, and depending on the area is up to 9 lam thick and is all teak. As for hard wear I went with the neptonic tuna mech and elect handle and then went with a heavy 11/32" shaft.

I have a question for all the gun makers in here.
I have been trying to find an Alternative for graphite since I am trying to make a multicolored dyed track. So saying that I have decided to choose Teflon powder which is white.
Would it work like graphite or would it not work for what I am trying to do?

Laminated teak. The muzzle will be 4" wide and will be composed of 9 1/2" teak strips.

Hello
I am currently making a 58" double roller speargun but, I can't find any company making rollers. Saying that does anyone know where i can locate rollers that will except the larger 18-19mm bands needed for this gun.

Any help would be greatly appreciated because I am on a relatively tight timeframe.

Thank you for your concern. Every year novice and advanced freedivers die from shallow water black. Saying that everyone is scared of diving theses lakes, since the vis is normally less then 5ft and there are some massive catfish. Down there.

Sadly I am not practicing with a buddy that's capible of reaching the depths needed, hell they can't even hit 20ft (why you don't smoke) let alone 60-100ft. Saying that I am by no means pushing my limits, and am instead focusing on bottom apnea time.

Hey yall

My name is Dennis jamison, and I am currently enrolled at the University of Alabama in Tuscaloosa Al . I am hoping to receive a degree in mechanical engineering, but specializing in hydrodynamics. I was born and raised in Sunny South Florida, and have been in the water for as long as I can remember. But saying that I never consistently Spearfished, or free dove until this last year when I left for college. I Instead opted for the Comfort of a boat and mechanical jigging or the thrill of land based shark fishing.

As far as diving goes, I got my basic certify in a lake in New Hampshire. I then proceeded to get my advanced open water and rescue diver certification in the Lower Caribbean. (Though I hate tank diving). As for freediving I still need a lot of practice and formal training. But I am slowly pushing my personal best for depth in the lakes surrounding Alabama. Anyways, I hope this forum can help me reach new depths (literally) and help me expand my limited knowledge base on this subject. Not to meantion help me with my speargun builds currently in progress.
