No I don't mean that overpriced graphite spray from Frankford Arsenal.
No I am not taking about the horrible realization you get when you discover you have been pushing a weld bead just a little bit to long on some aluminum sheet.
On lots of videos you see guys machining sheet or flat bar where they just cut a profile and the part or waste piece just drops out pretty as you please. How the hell do you do that?
Every time I try atleast a couple times during the job I'll get to hear the piece bind on the mill or bang off the inside of the mill enclosure. If I really need to do that I'll use the super glue and masking tape method to secure the whole work piece. Then unless the pieces are very small they just sit there without moving.
