• Another new guy- and new to the water as well.


    I finally had the opportunity to start diving (I currently live in Colorado) and am wrapping up the scuba diving certification bit (girl friend is avid scuba diver- just spent 3 weeks in Indonesia diving.) In the mean time, I've been playing underwater hockey- which is one of the sillier things I've done, but it turned me on to freediving- and to spearfishing- which has my woman rolling her eyes as I talk about long fins and not bothering with all the scuba gear. :)


    I'm an engineer by training, and like to make and service what I own and use- I build bicycle frames, rebuilt the 700R4 transmission in my truck (and it works properly), stuff like that. I've been looking for information about what makes a good fin- and thinking about it a fair bit, so I'm sure I'll end up making some fin blades. Any input would be deeply appreciated. To be clear- not looking to commercially make blades, have no interest in competing with Dan to sell blades, nothing- just what I like to do as a hobby.


    In the near future, we're looking at moving to some place like Bali, the north side of Aus, maybe the North Island of NZ... So I figure I ought to get going on spearfishing now!


    So thanks for having me.

  • Welcome man, lots of good info here; bar far where I have learned the most (aside from just going out and doing it that is). I too started off as a SCUBA guy but since I started freediving the bubble machine only comes out for fun dives or going deep and that too is rare these days as I almost always rather be freediving and spearing.

  • welcome...nice to have another builder/tinkerer on board...we have some really talented people outside of diving here..lots to learn from really good people.


    check the fins threads for some good info about properties etc for your blade build

    i like to spear fish

  • Welcome to the forum Dave.


    Apart from the satisfaction of making your gear I believe you will find making fins to not be worth it. You will have many failed tries before you figure out the way to get the stiffness and flex you want. Even then due to the resin and procedure used you will probably not get a fin that is comparable in quality to good commercially manufactured blades. I'm sorry to be discouraging but if money and time are an issue I think it's good that you know you're better off buying ready blades. Spearguns is a different matter :) Good luck if you do end up giving it a shot.

  • Thanks for the welcome.


    Dan, I just have a really hard time buying stuff that's getting made on the other side of the world. I'm sure it's not financially worth it to build my own, but at least they'll be made locally... :) And as with most things- it's a trade off of time and money- seems like I usually have the time or the money, but not both. And really, a little glass and resin and other odd bits don't really cost that much- I already have a vacuum pump for other stuff, and friends in the composites industry (they build carbon fiber bits for sporting goods companies and military applications, so I'll probably be picking their brains as well...)


    Thanks again for the welcome.


    Dave.
