Here are some pictures of the mini v8 I am building. I am having real progress on the at the moment, today I finished the combustion chambers and the valve porting. I am machining the heads in 3 major steps, milled from 75mm dia billet in my 4" cnc rotary table to +1.5mm all round, then mill to +.25mm all round and mill combustion chambers and valve bores and finish all drilling and tapping etc, then finally to size on all major surfaces for appearance, The 6061 ali machines well leaving a great finish when machined with inserted tools running fast. The project is gong to take the good part of 12 months but I will keep posting cool pictures as I go. I machined the combustion chambers with a 1/8 ball nose cutter and it left a few small ridges and am not sure if this will affect the combustion process. I still might clean them out prior to final assembly.
