I need an interference fit between a 50 mm shaft and a piece of mild steel 250 x 100 x 40 mm. This is for a part of an old 6 m elliot shapers that broke down. The part of the shaper is the stroke adjusting slider that drives the ram of the shaper., The shaft is BMS BRIGHT SHAFTING STEEL and the slider is mild steel ( I presume it is ansi 1050 mild steel.) The force that will be induced on this part is unknown, I can only presume it is fairly large. I can heat up the piece with the hole to about 300 deg c The question is to what size must I machine the hole in order to have a shrink fit that will withstand the force of the shaper The Coefficient of linear expansion α(1/ºC) of steel is indicated as 12x10-6. is this correct?????
