hello - I have a small question - an outside company has designed a shaft for us which is approximately 3 meters in length - it is approx. 100mm in dia. - the length tolerance specified on the drawing is +/-.13 mm (.005") - someone in our group said that this tolerance is impossible to hold on that length that .4mm (.015") was the best that was possible - I was wondering if that statement is true - I would think that w/ laser measurement devices & cnc machining it would be possible in this day in age - the shaft length does need to be held & I would assume that w/ some redesign it could be changed to fit this tolerance - any info would be greatly appreciated just for a better understanding for myself - thank you - i am re-posting this from the drafting board on the advice of the people there - material is 1045 steel w/ 125 finish at each end - thank you again
