Seriously me and my mate have put a lot of thought into this and have decided it is perfect. Trust me, there are so many variables in these calculations its like doing real maths...
Well, showing off a little bit. I'll have to work out a cost, but it will be somewhere round £5 - £8 a barrel.
One thing to note, in the pic you can see the boomy has the main diameter machined as well as the threaded section. So a bit of the outside will be machined back to bare metal.
