there are is a trade off between visibility and stealth

but i do appreciate your feedback if for any reason i do not feel safe with my trigger mech i will probable just buy a local Riffe

the real mech is going to be built much stronger and to greater tolerances , i am going to over kill it .

since i found out i cann't import it today , i decided to make it . because i am also making my own shafts as well ,[ATTACH][ATTACH][ATTACH][ATTACH]6726[/ATTACH][/ATTACH][/ATTACH][/ATTACH] i made the mock up to take only the 5/16 round stock , so i only have to make the retaining notch on the rear of the shaft not a full american style notch system . this is only the mock up made from 3/16 mild steel flat stock . i basically copied Neptonic's tuna mech [ my version ] . i can't cast the real one from cobalt alloy because my tools can't melt that much metal so i will source local stainless plate from a supplier . feel free to post constructive criticism as well as any mods.

in more than one aspect

Guys just spoke to my customs broker and she told me that spearguns are considered a grey area . You actually need a permit to import spearguns or speargun components but because it is for fishing most times customs let you pass . however if you meet an officer in a bad mood they do have the authority to confiscate them therefore a permit from the police department is necessary for importation . she said it is a relatively easy permit to get , not like a firearms permit . i therefore decided to try to make my own trigger mech , i do have access to jeweler style casting tools . going to try to cast them out of Chrome Cobalt alloy which does not contain any iron so it is not a stainless steel . it is extremely strong and will NEVER rust [ same alloy in hip transplants ] . when i get started i will make a new thread with pics . although if possible can any one post pics of their trigger mech internals . thanks .

true

thanks Dan , can a safety be used on Freedive Store's trigger mechs

welcome

thanks alot , customs can be a pain .

i live in Trinidad and a lot of the things i buy online i buy trough Bongous which is a shipping forwarder and also buys thing on your behalf then ships it to you . so i made an order for some parts , tuna mech trigger ,handle frame and line guide all from neptonic . Bongous emailed me today and said they can't make the order because speargun parts are considered weapon accessories . does this problem roll over to customs problems or shipping problems . any of you guys had this happen before .

thanks for the tips

yeah its a machine shop supplier they have all kinds of steel including stainless , besides the riffe shaft is $100 US and the local machine steel is $1.50 per foot at 5/16 . even if it bends it is cheap to replace . plus i am using a Neptonic Tuna Mech not Riffe .

yeah they know who the trouble makers are , although some times you can come across a difficult customs officer so be careful

your probably right , i will hit a wall with the gear that i bought . although just as a side note camo is illegal in Trinidad and Tobago , specifically military style like the kind the US Army used in the 90s and present but the customs officer is the one to decide if your particular pattern is illegal . so if coming to Trinidad and Tobago i would go with something like a black wet suit . caution is needed even with the camo style cargo shorts you guys wear. it can be confiscated .

even tough i'm new to the forum also WELCOME .

This is connected to my pitch pine thread . Shafts in Trinidad cost around $100 US a piece plus i would be fishing in shallow rocky areas , i therefore am afraid to use $100 dollar shafts so i will be making my own . I know this is a odd question but does anyone have the dimensions of the notch used on an 5/16 American style shaft to use with a Neptonic Tuna Mech . I can't source any locally to measure . I need the design and dimensions in order to cut the notch in the 5/16 spring steel round bar that i am buying . By the way buying spring steel from a machine shop supplier is 10 times cheaper . I don't want to be in the water and afraid to shoot a fish because i am worried about bending a shaft . thanks .

the wood is already kiln dried , i don't want to have to laminate because this is my first gun , i don't actually have a speargun and i don't want to have to wait 2 months before i can get in the water . is the laminating just preferred or will the gun not function without laminating due to warping

the grain looks pretty straight .

This is a cutting from the total 10ft length , it is just over 4ft x 2x4 . pure solid purple heart . i am not going to laminate it because it is going to be relatively short for reef may be mid handle plus it is my first gun besides the pine tester . is the laminating completely necessary .[ATTACH][ATTACH]6721[/ATTACH][/ATTACH]
