Carbide Tipped Dead Center

the carbide dead center will take more heat than a steel one so more speed can be used but watch out for the part center hole melting. also don't melt the silver solder. definitions, dead center part rotates with center live center parts spins on rotating tip. but part that spins on the tip of the dead center it now becomes a live center. interesting( to me anyway) is that od gringers use dead centers because the have no runout live centers have runout maybe not much but for the bearings to rotate there in space this space is runout. yes you need lube ep (extreme pressure) there is a lube just for that. watch your speed and tailstock pressure, you will note that a dead center in the headstock fill have a black line on it when the part is removed this s fretting. misalignment betweem headstock and tailstock can cause this not a big worry. bill (you can see why I didn't want to retype this )
