I have a totally manual workshop, consisting of an Atlas 10f lathe dating from the late 1930's, a Picador mill/drill from the 80's and a Herbert manual surface grinder from the 50's. I have restored them all and brought them up to date.
Later this year I hope to invest in a small CNC mill, as even with 3 axis digital readout on my mill it is very time consuming drilling and reaming so many holes in the projects I have undertaken.
I have already built and run numerous steam engines and one four stroke side valve, water cooled petrol engine.
At the moment I am building a few twin cylinder oscillators (wobblers for those in the US) and the attached picture shows what stage I am up to, they all need surface grinding all over, but that comes after the tapping stage.
