- Dec 18, 2013Give me a idea as to what you are makeing......Talking to a old guy .. pre cnc...I am asumeing you are makeing something form the od - outside part.... we would make a pattern our part out of of 1/8 in alum...and mount it to the outside of the ways of the lathe.... with enough room for the cross slide to betwen bed and still turn the cross slide by hand.,, ...........Then we ''''we would mount a peicce of 3/8 flat stock off the cross slide to hold a dile indecator on a magnetic base..............using the feed from head stock toward the tail stock you could fowel the patten while roughing out the part...when down to finish size you set the indicator on 0 and keep it zeroed on the patten while cutting...........finish with file to take out tool marks....cutting wood or steel or alum ?

Very much appreciated, but which tool(s) does one use to machine the curve once he has his desired curve shape?
