help with neptonics line release,

[jtkwest]

i just got a neptonics trigger for my next speargun project and the line release has led to a couple of questions: where exactly do i mount the set screw that works as a fulcrom for the release? it seems that it would be centered on the slot on trigger, but how far FROM the trigger does it need to be? also, there is no spring to reset it, is that normal? on my riffe guns, all have a spring. is it missing?or just doesnt call for one. i will take some pics and post them in here, soon.

Any luck with the trigger yet? Im just about to order a trigger from Neptonics too, and was actually going to see if anyone has had any experience with them here.

They look nice, any thoughts?

i think it may actually be an aimrite trigger sold by neptonics. it fits riffe spears, (like aimrite) and it looks identical, plus wong(aimrite) sells neptonics float lines with THEIR name on it , so maybe it is reciprocal relationship. either way it is a SOLID trigger! ken jones(deathstick spearguns maker/ owner) told me they are awesome and easy to fit , since they fit in a 1/2 inch slot. so that is why i got one. and the price is right. did you get the delrin track and the router bit? i did and i am gonna make a sick blue water teak laminate- full enclosed track for a 65" 9/32 spear with kitto slip tip. i cant wait.!

I just ordered my stuff from Josh over at neptonics, seems like a pretty solid cat. I think I remember him saying that aimrite or sea sniper (one of the two, though I cant remember which) uses HIS triggers.

This is my first gun so Im starting off small. Its actually going to be for my fiance. a 90cm teak railgun.

I ordered the reef trigger, template, 5/16 ball bit, handle frame and line maker. Cant wait till it gets here. I was going to go with the enclosed derlin track but I decided to save it until I build my bluewater gun. Post some pics when you get some progress, Ill do the same.

jtkwest... I just got my trigger set up. Did yours come with a set pin or screw for the line release?.. cause mine didnt. I see how the thing works but like you said how far do you need to mount that pin from the trigger housing? Let me know if you have figured any of this out

Aloha

yes, i was sent a threaded rod with a slotted end for "pinning" the line release. i got the "tuna" trigger but it looks the same on the pic as the "reef" i am gonna make custom jig to cut the line release slot. when i do maybe i could send it to you and you could use it and send it back.looking at this build, that is gonna be the hardest part.i was given the perfect solution as to how to do it from Deathstick maker. as far as neptonics is concerned, josh seems really cool and will make good on whatever. but i ordered the delrin track insert, with the router bit to match. DONT get that! it isnt good. the track on the one i got was cut off center and too small to allow easy passage of the spear, so i am sending it back and getting the ball end bit instead. i did some research and now i am just taking a 1/2" router bit and making a 1/2"x 1/2" deep groove by 55" down the center of the stock. (neptonics triggers fit into 1/2" groove) then make a little dam out of duct tape about 3 1/2" from trigger end and fill entire groove with epoxy mixed with graphite. leaving out the 3 1/2" slot for trigger. THEN cut a 1/4" x 1/4" groove into the epoxy with the SAME jig you used for 1/2" track,( thus being perfectly centered on trigger slot ) then you run your ball end bit through the 1/4" slot just keep changing bits but leave your jig on the router table the same the whole way through and you will always be on centerif you do it this way, your trigger will align with the track perfectly every time, and the epoxy and graphite mix is slick as grease and will bond to the stock making it stronger, if you dont do it this way, you are faced with trying to align trigger with your wood track, which is a HUGE pain in the arse, as far as where to place the pin that holds the relese, i am gonna make a mock barrel with the same dimensions and fit the triggerand try it to make sure where to put it exactly, when i do i will let you know, i just sent two barrels to wisconsin to be "trued" by a friend who works in a huge millwork company. when i get them back i will start working on them. what kind of laminates did you use? i used teak and some ipe glued together like an "
H" configuration

Yeah, I talked to Josh and he is sending me the threaded rod for the line release. He is a cool cat, I think it was left out of the original order so he is sending it first class. As far as the track, i was most nervous about cutting that. I made a mock stock too. i cut in the trigger and made sure it was going to work. Everything was perfect so I actually cut in my trigger and cut my track yesterday. My gun is just a rail gun so I had a little cushion there. Everything came out perfect and Im really happy with it. Thanks for offering up your jig but I cut the slot already...got my fingers crossed! Everything was alot easier than I had expected!

I used some teak I had left over. It was from a job I had done with some teak doors from bali. They sent Jam material but we ended up using the existing jams and I got to keep all the extra teak. Its really nice stuff, I just did 5 laminates. Its a small gun so the width is only about 1 5/8 wide by 1 1/2 thick. I still have enough teak left over to make my bluewater gun!

I guess the only thing that is making me nervouse now is how well it is going to perform. Im still intimidated by the whole ballasting procedure.

Ill let you know how it turns out and post some pics. Id be stoked to see your project too!

Aloha

And by the way, thanks for letting me know about the derlin track! I was going to order one for my next build, I think now I will do the poured epoxy track. Where did you get your graphite?

Posted some pics of the build so far. Check it out when you get the chance.
