Bristol Engines

[technicaltom]

Hi , I have been thinking more about these Bristol cylinder heads( 6 cylinder) , in a previous post i suggested a" modular " head might be easier cheaper to make, castings mold patterns etc. would be less complex , also machining would be less complex,
A futher thought occured to me ,why not have the easy part of the head,the lower half machined from a solid blank of alloy .this may sound like a lot of work,but it is not nowadays when you consider the number of engineering companys that have CNC Milling machines and very highly trained operators,
The CNC program only has to be created once.
