Hi All,
Im am new to this site and indeed spearfishing. I found this site yesterday- and can only wish id found it before designing and making a spear gun, having never even seen a production gun up close to study!
Using the images of existing spearguns i found on the net I gradually built up the ideas and workings of "a" speargun. In the sea it has prooved itself very effective- first time out i had a 22" Bass, 3rd time a 20" bass....then some time off due to a bent spear that cost me many a good fish!
Have just been in with my new flopper barbed spear that I made and all is well with my 3rd bass! Chuffed!
So anyway, i thought I'd post some pics of the gun for 2 reasons, 1) Id love some feedback from people who know what's what about spear fishing, and 2) to share the trigger mech I came up with as i was not able to find any info on design/making a simple mech......even though i should really patent it (but havnt got time, capital, or inclination to!)
The Plan drawing of the mech (speargun6) shows the 1 peice trigger milled from a high grade aerospace ali alloy (as i couldnt find a peice of 5mm stainless). The actual shape differs to that show as things changed slightly during construction, but the principle still works the same. In practise it works beautifully, is really easy to fire and surprisingly quiet and light. The one reason it might not be comercially viable is that it requires a safety pin to be inserted after spear is locked in, and before loading the rubber band- this is an absolute must!! But once loaded safety can be removed and trigger holds perfectly.
Other than that,the overall barrel length is 90cm, the construction is Oroco wood handle and front end, 1" alli tube with a 1.5mm deep groove for spear, alli spear retaining plate and trigger, 17mm rubber, stainless 6mm spear with flopper barb (also home made).
Well thanks for reading that if you did, look forward to discussing it with any one interested.
Almost forgot, im based in Swansea, UK if anyone needs a snorkeling/fishing buddy- there's 3 of us so far!!
