The near finished product

So this is the nearly finished product. all that needs to be done are a few minor touch ups (paint the bondo, secure the copper pipe to the ball valve somehow...) 

The hand guard is a little massive and the blade is too skinny but hey, £30, a couple of days each week for a couple of months and no help from my pops, I'm proud-ish. next time round this is going to be all metal and twice as accurate (And twice as frustrating). I didnt go for attaching a bike petrol tank in the end, and that would have doubled the cost of the project.

You can see the unpainted bondo here.
