Well...
I went to the hardware store, bought up all their air chisel bits...
Put one in my lathe, made a shouldered driver...
It worked fine.
No longer ascart.
Thanks,
Mark

Hi Guys;
New member, experienced machinist just starting head work here.
I tried driving in a false guide in a Caterpillar head, and killed it.
The guide is 3" long and .5015" diameter OD, 3/8" bore.
Really, .0015" interference? I did ream to .500" and she is right in there...
I am a bit scared of the air-hammer... but if that is what it takes.. I'll go with it.
I had made an aluminum pilot punch and was using a 3# hammer. A lot like work.
Also, is it better to drive from the top, like I did, or should I go from inside the bowl?
My many thanks!
Mark

Hi Guys;
I am busy just trying to keep the business running...
Customers want me to port and polish.
Well, I am not an airflow dynamics Engineer, I don't own a Dyno... and no interest in either.
As I am a all-out CNC shop... I wonder...
Is there a source for proven CAD models for various cylinder heads that I can just punch into my software and create tool-pathing?
Thanks,
Mark
