Chester Craftsman Lathe

Served an apprenticeship with Rolls-Royce car division in Crewe, went on to join the RAF, twelve years later went back to RR but now work in the NHS at my local hospital. Have a Chester DB10, Myford Mill and an old Clark horizontal saw. I will never be the best engineer in the world, or the country, in fact not even in Crewe but I am the best in my house so I will take that, please don't tell the boss, she might want proof of that statement. I have just started to dabble with 3D printing but can't find a cad program that I am happy with, possible because it has all changed so much since I first learned to use cad for draughting. Update, I am getting reasonable with Fusion 360 now.
