having been in the tool and die trade for 25 years i would like to add some things to this flatness of the maze 3.is it not true that the flatness only matter where it touches the core...the core is roughly .500 x .750 in size...and i have checked my maze3 with a .0001 indcator and i get it out no more than .0003 in this area.i need to check my core but i bet its out more than that...so all im trying to say is there is no need to get the whole back of the block flat...of which u will never do anyway with sand paper on a flat table....if u wanted to really get it flat u will need a laping plate...it would be a prefectly falt with groves in it in a hatch pattern...and u only use compounds to different grits just like sand paper...this takes a very good touch and alot of time....and only moving the block in a figure 8 pattern...changing grits to get the desired finish...all of this i believe is nosence with u are dealing with the small area as u are with the core size...ill check a core and see what it is actual out and reply back to this post


please if some one thinks iam totaly off base just let me know


byt the way i hope u can understand any off this i am in no means good with words...for that im sorry
