    No  they will not engage.  A 1-72 and a 2-56 are not compatible.  The
    72 and 56 are the threads per inch.  The 1 and 2 define the diameter. 
    If your rod is to tight, try drilling the hole for  tap 1 drill size
    larger before using your 1-72 tap.  That should work. Most standard
    drill sizes give a 70 -  80% thread engagement.  Going with a slightly
    larger drill will reduce the engagement but should make it easier to
    put together.
