This is probably old hat for most of you. How do I clamp work to a back plate? I have never turned anything on the back plate I have and now I need to bore an 1 1/2" wide hole in a piece of 1/2" x 3" x 5" aluminum. I don't have a four jaw handy yet, and I'm still trying to acquire a mill. So I'm stuck with finding a way to do this on my lathe. For reference I'm working on a 18" x 60" engine lathe. I do have a large back plate capable of holding the work piece, I just don't know what is usually used for clamping to the back plate.
Thanks in advance.
