Apologies in advance for my terrible camera/phone.
this is what i have so far for my shishkebab replica, from fallout 3.
I'm still waiting for the motorbike handle brake, but aside from that, it's nearly finished.
The round tsuba like piece is a piece of mdf with 16mm holes drilled around it. the piece that attaches to the tsuba is 1.5" ID pvc pipe, which i squeezed in a vice for a couple of days, to make sure it squished into an oval shape. I'm unsure whether the 4 parts covering the holes are flat headed screws that hold the blade in place, as the groove of the screw heads appear to curve downwards.
The copper pieces i used are 15mm in diameter will be weathered using bleach. The two valves are a 15mm gate valve and a 22mm ball valve. I got both on eBay for about £7. The blade itself is a 1.3" steel bar, which needs much more weathering(Read: Beat it against the corner of the garage wall!). I may replace this with a wider blade at some other point, to fill out the oval shaped piece more, and rust it up. I'm using the piece found on mountain bikes, used to change gears as the grip, as it has the right shape. But i may alter it a bit with some polymer clay or epoxy putty.
Thanks for listenin' chilldren!
