Faceplate Max Speed

Large 4 jaw chucks have t slots cut in them and when facing drum flanges sometimes we would put a t-nut and bolt in the slot and tighten against the flange to keep the chatter down. My brother was cruising along on the 60" Tuda facing a flange when the t-nut shot out of the chuck, went through a tool cabinet like a rifle shot.
