Hi Guys,
I'm looking for some help with a project I want to try. First some background....
I live in Northern Ireland, and the gun laws here are fairly draconian. To own an air rifle, I had to apply for a full Firearms Certificate which took about 8 months. I bought a Cometa 300N air rifle, which is a nice little rifle which works well and I really like it. However, it is slightly let down by its trigger assembly, which is a little rudimentary, so I would like to build a better trigger assembly from better materials. I've been told to sell it and get another rifle, but I like this one, it fits me well and I like a challenge, besides which I don't want to have to wait another 8-10 months to get another rifle added to my certificate. I am only interested in air rifles in any case, so I don't want more hassle with my certificate.
Anyway, this is what the parts look like disassembled, I want to attempt to make all these parts new.
(See pic attached)
The middle bit is actually made from thin sheets of steel which have been stamped out and rivetted together, I want to machine this from solid material so I can get a good polish on the contact faces. Is steel the best material to use, or should I consider other alternatives?
I think the trigger blade part will be the most difficult, so I'll leave that to last, but ideas would be welcome, as you can see in the photo, it has a bent piece which acts on the middle piece, but there is also a spring integrated, so this will need some thinking.
Any help wrt to materials to use etc would be gratefully received.
Stefan.
