This drawing I've made at factory where I worked as part timer, when I'm waiting the material in other machine to be done, I'm have nothing to do, so I drew this thing. This machine used to cut any steel in any shape, but it took a looong time to finish it because it was an old technology. Also this machine were a troublesome machine! If the wire broke, you have to start it again and must be quick or the material began to rusty and the wire easily snapped and sometime the work table won't move especially going for the move 'y', it happened when I'm going to cut in round shape on the plate but about in the quarter, the table weren't move, so you get a upside down shaped 'J'. Darn! Got scolded by my boss!
