Cassette in a wood gun?

[Myoungki Oh]

I'm looking to build a spear gun, I do have a wood blank and i need a trigger and other bits and pieces. When looking at triggers, I decided buying one is better than making one, (just the time and cost analysis) and that I should look at all types of trigger mechs. I found that cassette mechanisms for barrel guns are substantially more affordable than the metal trigger mechanism everyone buys for their wood guns. Would a cassette type mechanism work for a wood gun?

I have found buying old guns at garage sales can be a good source of parts. I picked up 2 seahornets 1 undersea and a mares gun for $20 the lot recently. The seahornet has a trigger cassette suitable for use in a wooden gun. It is an Australian made gun but sold all over the world. If you are lucky enough to find an old one, they used to make the cassettes out of stainless steel which is better than the later ones which are plastic. The guns i bought had plastic cassettes so I copied the cassettes in stainless steel. This may be a bit difficult if you are not experienced in metal work.

sea hornet cassette with trigger removed and my stainless copy. The top left is a cassette from the 1980s or 90s you will notice the trigger pin hole is closer to the apex than the cassette below it. the lower cassette is from the 2000s and is stronger than the 80s model. The ones from the 70s and early 80s have stainless cassettes but they are harder to find.
Good luck with your build

I don't see why not - although some brands may not be up to power of more than 2x16mm bands. The RA plastic cassette should be tougher than most and is simply held in with 2 plastic dowels.
[I think Mako & Neptonics offer good metal trigger mechs.]
