I like it. Why is there wood in front of the roller. Seems like wasted stock but I am ignorant
The wood that is forward of the roller is so I can attach the roller retainer to it. I thinking of using an eye bolt bent 90*. This is to ensure that the band does NOT come out of the pocket.
Cool gun. How much programming time invested in getting in cut on that really cool Laguna?
Programming time took about a day plus. The gun has some really simple features that can be done on any router or mill by hand.
So the polespear was successful why not try to build a gun.
This build has been in process over the last month and a half. Here are the specs of my build
90cm Custom CNC'd Roller Gun
Neptonics Reverse Mech
Riffe 9/32" Shaft
Mako Slip Tip
Hammerhead Remora 50m Reel
Mako AR-15 Handle
Custom Shaped ERGO AR-15 Grip
Rollers - Temp, I have custom rollers on order
Overall, I had an amazing time designing and building the stock. I worked with the engineer at laguna tools to help prove out his new 4-axis CNC Turner :thumbsup2:. The design is a double action roller that has a notch for 250% and 300% band stretch. There is a few pieces missing like the retainers on the rollers and the retainer for the notches. I plan on building this particular one as a prototype to prove my roller design and make the final gun out of padauk (I already have the stock).
Let Me Know What you think!!!
Ill most definitely call tomorrow. Thanks guys!
Hey everyone!
Yesterday I purchased an older Mako Iconic Pro, which I believe turned into the oceanic pro. So after being to excited about my new purchase I decided to take it out and try it. Within five minutes getting into the water and loading it, the loading butt broke! Luckily no injuries were sustained. I need some guidance as to what to do given I am the second owner and can not find a replacement part on the mako site. Given its the weekend I have not tried calling so...
Any help would be wonderful!
Not for sure but looking closely at the OP maybe he was not looking to improve range or performance, but going to sharkfin/open muzzle so he could tie his own bands in the "spectra/dynema. Nothing was mentioned about improving, range etc. per se, only looking for options to make his gun more usable. It's only a thought

This was my intent. But I would like to thank everyone for your knowledge and opinions. With that being said, I need a new gun :idea2:
Thanks Phil! I saw that link some months ago and that's what got me started.
Just to make your point clear here is the shaft notch we are talking about.
Dan is correct I do NOT have the kitto mech. The shaft I have uses a square knotch but I does not have the flat portion like most American shafts. Also my jbl shaft has two flats where it would engage the mechanism. So would an American shaft work with modifications, maybe?
I currently have a JBL custom, I am looking for a shark fin shaft. I was wondering if a standard american mechanism shaft will fit a jbl mechanism. I am aware the JBL sells a shark fin shaft for there elite models, but I would like a little more variety in my choice. I will by changing over to an open muzzle design. If any one has any insight on this subject please share! Thanks.
I am going to do some static testing to measure the deflection and the center or mid plane at each length with the tip installed. I was wondering what a good weight would be to hand in the middle of the spear, 5-10 pounds or more?
Thank you, everyone!
And this is why it is three pieces.
This is all three pieces and two tips.
White or silver carbon fiber. I
Total without some of the tooling I think I'm in the spear around $100. Time wise it took me about 20 hours on the lathe, no digital read out. The rest only took about 30 minutes to bond everything together, 1 day to cure and maybe another twenty to thirty minutes to do the heat shrink tubing.
FIRST PROJECT!
What I have created is a three piece carbon fiber pole spear. The spear breaks down into three, two foot sections, each with the possibility of having a tip threaded to the end. The thread I used was a 3/8-24, to accomodate GAT-KU tips. The threaded adapters and base plug were hand turned on a lathe using 304 SS. To ensure that the carbon fiber does not fray or become damaged when hitting rocks or traveling, I used a thick industrial heat shrink tubing.
Here is a rendering of the design before I started the manufacturing process.
The base plug, or where the sling is attached has two holes to either accomodate a float line or if I dare a second power band.
Polished of course!
All three sections with tip. A little over 7'.
Two sections or 5' with tip
A little scuplin ceviche courtesy of my three piece taco maker.
Sculpin is just another rock fish, so I normally make ceviche or tacos. With the croaker I have made tacos, panko breaded fish and chips, stew, just about anything you normally use white fish for.
My buddy and I dove the power plant around 11:30 in the afternoon. Water temp was good probably around 62-65. Vis was 5-10 feet. We ended up getting a good size sculpin and a 17" spot fin croaker. No halibut in sight, lots of BIG bat rays. In all a good trip, but the wind chop was pretty hard to deal with.
So I am planning to build a new speargun. As of now I am just using my CAD program (Solidworks) to lay out ideas.
My questions:
What would the dimension be between the top of a trigger mechanism (any mechanism) and the center line of the shaft?
For low visability hunting (So. Cal), what type of track is recommended?
Material? I have access to a full machine shop, So... what material, wood, hybrid, Carbon Fiber?

Hey everyone!
My name is Joe, and I am a functioning spearoholic. Now that I got that off my chest, let the real introduction begin. During my time out of the water I am a design and test engineer for an aerospace bearing company in Orange County. In my free time when the visibility is really bad, I design some speargun ideas in my CAD program. Hopefully in the near future I will be seeking some advice for building my first gun. The homemade 3 piece carbon pole spear is almost finished so I need a new project.
