<VV> new heads, VirtualVairs Digest, Vol 54, Issue 53

 Sounds like you've never seen a six axis machining center in action before! In a three up head, what's funny shaped? It's a nice big rectangular part! All you need is a couple of registration points to make it mount up the right way. 

These machines aren't a headache, they're a joy to behold! And they aren't even particularly expensive to run. And wow, the flexibility of what you can do!! 

CNC and SAMs are how things are done these days, and for VERY good reasons.

The big  advantage with the lathe is that with bar feed, you have something 
to hold  the part you are making.  With a mill approach, there is a large  
expense ( and headache ) in trying to figure out how to hold that funny  
shaped part.

In our toy car business, we have run  thousands of button heads for the 
little engines, mostly all hemi-heads,  with  various double bubble, 
tapered, 
low compression, high squish  ... just a minute or so changing programs for 
different test  heads.

I think a good setup for the new heads would be 3  injectors per side, with 
a 
central mounted air throttle, or 6 Mikuni s,  with hydraulic or pnuematic 
linkages on the throttle bodies.

just  some thoughts, ken campbell, deltawerkes 



I had shown my images to several Fastvair contributors (including yourself) 
 with the idea of using a mill to machine the head rather than turning it 
on  a lathe, then milling it.  One or two of these people voiced their 
approval  (it's been 50 years since I had machine shop in high school, and 35 
years since  I took a course in night school at the local tech. school; they had 

CNC  machines, but that was only for the advanced students.)
