I have been Machining two stroke combustion chambers for 25 plus years on my manual lathe. And have been learning CNC machining (self taught) for about 14 years. So I decided to CNC Mill a head chamber/dome . This is a YZ85 I did the other day. I'll post a finish pic of it to where i did the final very light clean up and polish on the manual lathe. I am pretty pumped on how the milling went.
