  • Harley Hemi Heads

    After reading the article on welding harley cases and the article wthin on hemi head harleys i got curious how would be the best way to machine those heads into a Hemi type shape. After welding building them up would you use a radius type holdridge tool to do it or calculate points with a design program like mastercam.. I dont have a cnc machine(YET) so I generally use =mastercam to calculate cut points for outside contours and file to shape. ALA GUY LAUTARDS spere and ball generating booklet. Any thoughts gentlemen (And David LOL)

    I'm interested in these articles, are they in HSM or off the net.
    Most of the work I have viewed in mags and on the net are more welding up into a bathtub shape this gives more squish. I have a MERCH 120 ci engine new not even assembled yet that I purchased at their auction. 4.25x 4.25 they use a hemi. type combustion chamber with a squish zone of about a 7/16 all the way around the circumference of the chamber. I could take a pick of it if you want to see what it looks like.
    Sorry I just looked at the harley case post.
