Default Nova 1

I have start the build of an new(old) engine , the "NOVA 1"
It is a 4,5 cc diesel designed by a Dutchman I.J.v.Leeuwen in 1943 , during WW2
I have made my own castings for this engine , it was my first attempt of aluminium casting but it's actually pretty good
Here are some pictures of the casting procedure


Greetings Jef

I've started machining the cilinder , it's quite a job turning the 42CrMo4 steel and the cooling fins are only 0,5 mm thick , that's only 0,02 of an inch
