it could be a couple things
ratio is off , never very the ratio on epoxy ,adding more or less hardener will only make the resin not cure corectly
too much pigment
adding the pigment before the resin is mixed . you should never add anything to the resin until the A and B sides are fully mixed
my guess is a combo of all 3

Good info, thanks Phil. Probably a great mech for a bluewater gun, but more of a hindrance than an advantage for a two band speargun. The top of the mech housing being round, I can't remember if the notch has to be purposefully aligned down, which would not be intuitive. Correct me if I'm wrong on this.
that is correct but with the depth of the track the shark fins on the shaft line it up enuff for it to pop in. it is a little over kill for a 2-3 band gun but it is a very smooth firing mech
phil
regarding the elite mech . it is a 3 piece mech with the highest fail load / lightest /smoothest trigger pull under load of any trigger on the market . the trade off is to load the shaft you have to overcome the mechanical advantage of the internals of the mech , it takes about 7#-10# of force to engage the shaft in the mech . but with a 1000# of load the trigger pull will only be around4#- 5#
phil
The jbl elite guns are very good guns . Basicly a slightly wider riffe standard ,with a much better trigger and a plastic muzzle ,and a good handle shape . Get the shark fin shaft, open muzzle model.

Language is something that evolves over time and in use circles . Since true "open cell" is not used in in the wet suit industry I could care less what it is in another industry. since in The wet suit ,open cell = a unlined ,cut finish neoprene ,then that's what it is .
Phil
I don't know how much difference it makes ,but 10# of steel won't weight 10# in water it will "float" a little .

the problem with saying dive Rs are too stiff is the fact that they come in different stiffness's and you only had the mediums . i dont see any reason you cant make a fin blade that can be layered out to not need tendons . blades are the simplest thing in the world to lay up and they are still all made with the simplest production minded way possible . anyone with a little composite know how and a little skill and the right parts can make a blade in their garage as good as the best on the market after a couple trys to get the method and stiffness profile down

i like this part,
The bill would require the department to develop and adopt a method to impose and collect entry pass fees onsite for visitors that are engaging in nonconsumptive uses, as defined, at state wildlife refuges and other lands managed by the department that are open to the public. The bill would require the department to modify its online processes for purchase of entry passes and warden stamps to make these systems user-friendly for nonconsumptive users.
im sick of the kayakers and birdwatchers ,who pay nothing to use the ca waterfowl refuges using them for free when ,we the hunters and fisherman are paying for them .

I'm planning on diving for WSB!!
X1000
4 hour drive north for 3 snails ,that i mostly just give to friends vs 4 hour drive south for wsb ,no question where im going

Display MoreHere's the bouyancy test for the Aimrite Reef float. As mentioned previously it's an older model but I was told the dimensions and stated bouyancy are the same as the current red/orange model; 39" long by 12" wide - 48lb.
The float was inflated by mouth as much as was possible. It had 37lb of lift in the pool. Multiplying by 1.025 to get saltwater bouyancy results in almost 38llb, 10lb less than Aimrite's stated bouyancy. After testing the Speardiver float this is more or less what I expected. Based on these tests and its dimensions I believe Aimrite's Bluewater float bouyancy will be significantly less than the stated 90lb.
Aimrite Reef Float Buoyancy Test - YouTube
I took the opportunity to retest the Speardiver float, this time without the ballast. It measured 43lb of lift. Multiplied by 1.025 results in 44lb bouyancy in saltwater. Same as the previous result.
i see one potential problem with how you are using the scale in the video it looks like you are holding it at a angle . a spring scale will give a lower reading if there is any side load at all on it, even a tiny bit of angle . to get a accurate reading hold it by a rope loop on the bottom of the scale .or to remove all doubt hand weights off the float until it goes neutral and compare that to the scale reading.

Display MoreYour footpocket/blade combination amazes me. Stingray f/p are the stiffest I've seen, and DiveR blades are the heaviest/bulkiest. Your legs must be strong. If you try Pathos with carbon blades you'll feel like you're wearing a feather on each foot, it will spoil you. If you need a burst of power you will be able to fin very quickly. If you try to fin quickly with your fins your best effort would be limited to the fins do their own thing. Because you're used to these heavy fins I think you'll be happy with a medium+ stiffness blade, combined with Pathos f/p having a little more backbone will be a good thing.
Blade length is a personal choice, I offer C90 and C100, the latter being the same length as the DiveR. But for the diving I do I see no need for the C100.
Water channeling rails are very good for stabilizing the fin and eliminating the slippage effect. Sculling movements become a little more difficult but as freedivers we rarely use this kind of kick.
I also think you will enjoy going back to a conventional 20 degree toe angle.
These are the DiveR blades I tried a few years back, they were sold after 2 dives. I was fortunate that the carbon fins arrived at the same time and I was able to make a side by side comparison.
what stiffness dive Rs did you have ?

Display MoreHi all
I am looking at doing a baked finish on a laminated gun i have just finished, actually i've had a guy offer to do it for free so i'm seriously considering it.
However
On the West systems site it states that the 105 resin/hardener can handle temperatures of 200 degrees Fahrenheit (93 deg celsius), the finish requires the gun to be baked at 176 degrees Fahrenheit (80 degrees).
Do you think the timber glue lines will be able to hold up to this sort of temperature, my thought is at this temp the resin will soften and the timber will expand and ruin the laminations.
Any thoughts!!
the resin will soften at that temp ,and if anything bad happens depends on how stable your wood is, the odds i would give it are 20% it works fine, 40% there is a little movement but it is ok , 40% catastrophic failure .
i am baseing my odd on what i have seen happen to a black epoxy coated gun left out in the sun all day

i haven't worn a watch on dry land for at least 20 years. i have a clock on my phone ,and pager before that . and if i dont have to have my phone on me,i dont need to know the time ether.
phil
Thanks. Makes a 1-2lb difference with the available floats.
What about my test, is it valid?
yes your test is valid .
if you inflate to a higher pressure,like 30psi instead of 15psi (assuming the size stays the same )flotation at the surface will stay the about the same ,but at depth flotation will be higher than same float that is at a lower pressure that is crushed .
as the pressure the float is inflated with increases, the flotation will actually decrease because of the weight of the compressed air. but it will maintain that displacement to the to the atm # its inflated to
.for example:
a 10# displacement float inflated to 30psi (2 atm) will still displace 10# at 66'sw at 99' it will displace 5# and at 132' it will displace 2.5#
most riffe and aimrite floats i see people use are only full ,and really dont have more than 4-5 psi in them ,if a fish takes it past 33' its gone and not coming back
phil
i wear a 7 mill most of the year . 1# to 1.5# ankle weights really help by making your legs a little less buoyant ,where i really notice the difference is in strong currents trying to get back to the boat . when im in Florida i never wear ,and dont see a need for ankle weights
phil
i have it set up with thin line for the next test ,i dont think in this case it matters because of the nose dia,both lines sit in the same place on the swivels ,but i will use 2mm spectra so there is no question on the results.
phil
no problem i will do it tomorrow. i need to refilm the swivel test anyway , so i will do them both at the same time
phil
thanks , is that good enuff for you ,i just grabbed some guns and snapped a pic. i can set it up however you want it.
phil
i just sent some pics over , but did it before i read this and i unstrung the guns so you could see it better , i can take more with the line on if you want , look at what i sent and let me know what changes you want
phil
there are a couple pics here
