Meet Henry
he's looking very smug. I've left him alone with the internet and he's been reading all about fluid dynamics, flow benches, cylinder heads, and all sorts of stuff. I have to keep him in the cupboard, because, quite frankly, he's a bit of a bore. Still, he's handy to have around because I have no idea about any of that stuff, and one of us has to understand what I'm trying to do...
Anyway, Henry told me I was pissing in the wind poking my fingers inside cylinder head ports and measuring stuff with verniers, what I needed was an Arc, errm, I mean plenum He gets a bit carried away sometimes
As luck would have it I came across a bit of worktop in a skip at work, with a thumbs up from Henry I slipped it into the Twingo and brought it home.
He told me I needed to build it 300 cubits long, 50 cubits wide, and 30 cubits high. I have no idea how big a cubit is, so I ignored him and built it with internal dimensions of 17cm x 17cm x 34cm.
why 17x17? that's how deep the throat is on my bandsaw is. Why 34cm long? That gives it about a 10L volume. Why a 10L volume? I don't know, it looked about right
It's only screwed together at the moment, once it's finished I'll pull it apart and seal all the edges with silicon, apparently it's important to measure the flow through the head rather than how leaky the plenum is....
So, what next? I have no idea, Henry has taken the hump about the whole cubit thing and is no longer speaking to me.
