Looks good Dan. Is there a wrist lanyard?

I dont know about everyone else but Im not bored keepem coming. Assuming that the images are much clearer in "real life" the camera did a very good job. The color is really vibrant and the contrast isnt bad either. It also looks like it has a pretty powerful zoom. Either that or these are the friendliest fish on the planet.
Nice pics, looks like an awesome trip!

I like the look of the beuchat guns and a lot of the guys I worked with last summer liked them but they dont compare to the rob allen guns. The Rob Allens are tanks I dont think it would make sense to go to a beuchat if you like your RA. If you were really interested in trying another gun I would suggest a Riffe euro.

would something like this work?

I know I dont need one. I was just curious at what weight it becomes a good idea to have one. I just like to know stuff lol. Every now and then it becomes helpful.
-
I hope this isnt a derail but how much weight would you need before a vest is a good idea? I dont wear a lot of weight especially without a suit on and I know you need to be able to drop a good portion of the weight in an emergency so I was just curious. Don was talking about wearing close to 14 lbs of lead total but I usually only have about half of that on with a 3mm suit.

Generally people who make an enclosed track gun and plan on using an epoxy finish will use the poured track method. What you described is basically the same only the shape of the bit is different. If you do it your way and you put a thin coat of epoxy over a wood enclosed track you run the risk of having a thin spot that might wear through or not be thick enough to provide a moisture barrier. It is also going to pretty hard to realign the track with the router or mill once you have pulled it out and coated it.
I would also suggest applying the epoxy at the very end because even after it has cured over night the epoxy is still relatively soft for a few days and you run the risk of damaging the coating unless you have the time to wait for it to fully harden.
TL;DR Yes your method would work but its not the best or easiest way to do it.

Well, as a speed skater in my high school days.... you have used an analogy that I can relate to
Now, even in a "loose" enclosed track, where some shaft whip is occurring, and perhaps the track is a bit warped also...... can we imagine the squeeze film still acting in places along the track, even just for an instant, as the shaft is forced to contact the track? I picture a shaft kind of bouncing around in the track as it accelerates, but the squeeze film does what it can to cushion the shaft as it moves forward, reducing impact, kind of like Magnetic Levitation....
Yes you can. This is known as squeeze film dampening. It will have some effect and there are instances especially towards the end of the shot, once the shaft has started moving and there is less flex, where the squeeze film will occur.

I wasn't saying that squeeze films don't exist only that they arent really present in a speargun. Many aspects of modern life wouldnt be possible without squeeze films and their application in hydrodynamic bearings and lubrication.
The experimentation I was referring two was more the trial and error of different builders trying different materials and techniques for building tracks and arriving at the current solutions. I guess it would be more of an evolution in that regard.
I didnt say that water cant work as a lubricant or form a film but Im sure you can agree that oil is a better lubricant. Your right about the ice skates but the shape of the blade plays an important role. If the bottom of the blade was rounded or sharp like some people think they wouldn't work. As Im sure you know for the squeeze film to form the shapes need to be very close and the gap between the surfaces has to be very small. Also having a higher viscosity liquid helps. I wasnt suggesting that a squeeze film cant or doesnt form only that because of how wide the gap is relative to the spear diameter makes it easier for the water to flow around the shaft and makes the effects of the the squeeze film minimal compared to other forces. Squeeze films and hydrodynamic bearings require much tighter tolerances than are found in speargun tracks.
This is further reinforced by the trend to use low friction materials . A squeeze film would reduce the friction to the point that material choice would have minimal effect and the extra work to make a the track out of a different material wouldnt be worth it. It would be easier to just make it out of wood.

Im not sure a squeeze film is forming in this scenario. Most enclosed tracks that I know of are intentionally made larger than the shaft so that they can function with slightly bent shafts or sand/debris in them. A good quote I read once was that you want your enclosed like an ak-47. It needs to be able to shoot every time even if there is a slight flaw in the shaft or barrel etc. Under ideal conditions a squeeze film might form and in the field you may see a partial squeeze film but I dont think this happens in most if any guns. Another problem with the squeeze film model is that it requires the shaft to move parallel to the track but it is known that on overpowered guns (one of the big reasons people choose enclosed track) and even normally powered guns the shaft flexes and does contact the track walls. If you watch slow mo videos of open track guns you can see how much the shaft flexes. The ability of the track to contain that flex and direct the forces into moving the shaft instead of flexing it. Additionally the oil used in engine lubricants is significantly more viscus and is chosen for its cohesion and ability to form a film. Water is not nearly as good as a lubricant.
Like you mentioned Dustyyoungblood track material wouldnt matter if that was the case but experimentation has shown that the UHMW and epoxy are the best.

I dont know how much better that would be. epoxy with graphite is pretty slick already. The metal track would be loud. The shaft would rattle and scrape on the shot. Another problem is the expansion and contraction rate of wood when its wet and as temperature changes. The epoxy tracks dont have a problem with this, the UHMW have a slight problem and as a result cant be glued in. I would imagine you would run into some kind of problem with this. Also by looking at your diagram there is a small gap between the metal and the wood. This could potentially hold water and cause the metal to rust. Its stainLESS not stain proof it can still rust although this is obviously a long term not short term problem. Its also heavy, some guns would have a problem floating that extra mass.
Try it see how it works.

If you have small hands then the Riffe Euro grip should be very comfortable. A lot of people complain about is how small the grip is.

The spines will still sting after the fish is dead and I would definitely cut them off before filleting. the guy in the first video cuts them of at the base. The guy in the fillet video is nuts.
A propane torch will neutralize the venom. It is recommended that anyone targeting lion fish wear puncture proof gloves and or have a hot source of water handy. If your stung immediately place the affected area in hot water. The temperature of the hot water should be as hot as bearable without burning. Note: this doesnt neutralize the venom only alleviate the pain.
For cutting of the spines the best solution I have seen are surgical sheers or kitchen sheers. The surgical sheers are cheap and hold up pretty well in saltwater. I have seen videos of people using a dive knife to break off the spines similar to cutting off the ends of beans but I wouldnt recommend this technique especially underwater.

The material used to build both guns is Teak. It is a widely used wood for spearguns so neither gun has the advantage in this category.
As Sadot mentioned the Andre guns come standard with 14mm bands vs the Riffe with 16mm. These can be easily changed of course but for this comparison lets look at the original versions.
The Cost of a Riffe Euro 130 = 530 US vs the cost of the andre Euro series 630+ US.
Both guns are known to be very accurate and well made. The Andre guns are made in smaller numbers vs the Riffe guns that are made in a factory. Riffe has a 3 year warranty vs the Andre 2 year warranty.
The handle is more of a personal preference. I personally like the Riffe handle a lot and have never used an Andre gun.
As for the recoil " levanta un poco mas la punta cuando dispara" known as muzzle flip its hard to tell in the video because of how different the shots are. The Andre is fired from an aspetto position while the Riffe is strait down. Also the Riffe is set up with a reel and it looks like the Andre has some sort of break away setup.
In my opinion either gun is a good choice. I have heard of some quality issues with the Andre guns and some people dont like them. I personally am a big fan of the Riffe euro series. I love my euro 90x and have never had a problem with Riffe. Also after having built my own speargun Riffe is the only gun I would buy off the shelf.
I hope this gives you a pretty good comparison. I tried to keep it as unbiased as possible until my opinion at the end. I also tried to avoid the idioms and some of the more odd english phrases so that it would be easier to translate.

Get the leather. Just put down a towel if you are really wet. Cloth seats start to smell if they get wet and its pretty nasty after it sits in Florida heat. If you really want the leather to last just use a good leather conditioner when you clean the car.

Im not sure exactly what your trying to ask. If you post it in spanish might have a better time but google translate isnt helping much in this case.

Like I said Dan knows his stuff. Sorry for the misleading info.
Thanks for the correction Dan.

Do you want to know about millennium pockets or stingray pockets? They are different. The 46-48 is the largest size that is made. The 8 1/2 - 10 is improperly marked. I wear a size 11 US and the pathos 44-45 fits perfectly.
Both the millennium and stingray pockets run a bit larger and are very good for people with wide feet. The stingray pockets are not quite as wide but run a bit larger. I would suggest that you take a measurement of your foot in cm and send it to Dan and he will be able to find the proper size footpocket. In my opinion the millennium pockets are better because the Stingrays are too soft. Im sure Dan will comment and explain things a little better. He has done extensive testing on footpockets and nobody knows the pursuit carbon blades better.

Sorry Dennis I wasnt referring to your equation. I was referring to the one posted by Ladvr
Buoyancy = weight of displaced fluid
The one you posted is correct and is just a simple ratio.
