steady on lee... im just yanking your chain.... hope it fits together like a glove, theres nowt worse than having to re-work holes (or in laymans terms, re-insert the drill and swing around a bit)

mucho respect for drawing yours out on paper, thats got to take some mental accrobatics, i would have struggled without the 3D drawings... its soooooo easy to re-work a drawing compared to re designing during a build but, like i said marking out by hand always manages to catch me out a mm or two hear and there no matter how careful i try to be, hopfully steve has saved you the pleasure :)
