    The helix function on my machining center can be very useful. Just made up a single tooth fly cutter the right tooth form and told the machine to helix to a certain depth, and there you have it, a spout for my alloy E85 tank.
    Interesting the pitch is 6.35mm, 1/4" , why is that I wonder?

    We don't see many heads without a coolant exit these days..... BTW, nice plug.

    The exit, not shown (by way of not being made yet), water is forced past the base of the plug (with small fins not machined yet) before it can leave for the radiator. But I guess you know that.

    Finish the fuel tank now, with internal fuel pump, then on to the radiator manufacture.

    Nice one Neil . This is the sort of thing that makes me wonder: "Why didn't I think of that?" But I comfort myself with the thought that your cooling layout with radial water flow over the combustion chamber is not too different from mine.

    swivel? Like a turret?
    Yes I also thought it looked like a flying saucer with a large gun😆, a little sparkplug man in control.

    Swivel, yes its not bolted down yet. Head can fit one of two ways (injector top mounting lugs) but outlet can go six differnt possitions. It will point straigh forward.

    Ok, time to get serious, out with the old Heath Robinson furnace and in with the new. Old furnace did its job but it's time is up. Two crucibles so if there is a cock up on a weeked pour, (shit happens) I have a spare.
    Bags are furnace linner cement, they don't give this shit away!

    thats some nice work . seems like there was a kevin cameron article about heads and it descibed something similar to yours. baffling that alot of after market companies are still getting it all wrong

    what machine did you use to make the parts ?

    peewee, I am fortunate enough to have a CNC lathe and machining centre for my work. Real handy come the weekend. It's all run by Gibbs Cam full 3D but I am only really capable of the 2 1/2 D function, never the less powerful software. And a very comprehensive aluminium off cuts bin.
    Whats been lacking is a decient foundry facility, what I had worked and would still work but it's just close to the edge of disaster every time I use it, too 'hit and miss'. I want somthing I can rely on, every time. And under cover too this time, so not weather dependent.
    My problem, amongst the many, is I want to cast LM13 and no foundry in NZ will cast this in low volume like I want,

    I love how they call the cement Vesuvius. I hope it's not an omen of things to come.
    Based on past experience that is. Of the day it was raining molten Aluminum.

    Meh, normal for Neil.

    I was shown the hardening room at Alec Farrar's in ChCh a couple of days after they'd had a switchboard explosion.

    A copper plated room - very impressive.
