Well done Daz,
I am starting to get a horrible feeling that you are chasing my tail and about to put me to shame at how quickly your build in progressing! Its nice to see some pictures of everything we have talked about. Its looking like a very nice build. You are lucky, your steel is still clean without the dreaded red stuff.
Shame you are short of the material for 1 bush tube but that should stop you completing it before me LOL
