Wandering the internet today, I came across an old friend, The Gingery Press.
If you haven’t come across them in your makers travels you are in for a treat. They have some wonderful reprinted books with some fantastic vintage know how. The processes we use nowadays use a lot of the same techniques, just with a computer operating the machine instead of a human, but the old processes still apply.
A great reference for casting metals, making your own crucibles, making your own Lathe, welding with thermite, Injection molding, vacuum forming, coil winding the list goes on and on.
