HOWTO make a steampunk prop rifle

Instructables user Gmjhowe created this "Steampunk Dystopian Sniper Rifle " prop, which "fires a compressed sliver of frozen mercury at ultrahigh velocity" (this last part is imaginary). The process of building it is well-documented, and the result is fab.

I decided to make it recognizably steampunk, while staying true to my own style.

Ive used a lot of metal, and a lot of card. and a lot of other stuff, so much inf act that there is no point me creating a list of items. The main barrel is made from metal, and the handle and stock is mostly card, dense card with a layer of corrugated.

Ok, this is about 5 weeks of work, off and on, i will try my best to explain, but its pretty length, so im gonna try and keep it short and sweet.
