I'm well. Suffering from raging poverty but other than that I'm fine.
I'm most proud of the wax master & RTV mould in this post viewtopic.php?f=2&t=6534#p75600
That was real tough. The casting bit has had its moments but the master took months of experimentation. I blended my own machining wax, had to grind a tapered cutter to get the right draft, and so on, and so on.
Anyway, on the home stretch now.
I firmly believe that if large valved engines are ever to be affordable, the only solution is cast parts.
