Drilling air

Hey all..... I am attempting to drill a roughly 7.5 x 6.5 block of steel mounted on my indexer at 10deg.. I touch off Z on the high side away from the indexer and drill toward the indexer... My problem is when I'm on the last few holes in the row, the space from Z increases by .861 and I just peck at air for 15 seconds until I finally hit the part and drill my hole... I"m loosing about 20 minutes per part easily.. I tried to move Z closer after my X move but it always goes up to he R plane to start the drill cycle.... Here's my code for the first few holes and what I did to try to fix it... (with no luck)..


O0001(SUB.DRILL1)

N5 M21
N10 G90G54
N15 G99G83R.1Q.1F5.5L0
N20 X1.496Z-.392
N25 X2.309Z-.535
N30 X3.123Z-.679
N35 X3.936Z-.822
N40 X4.750Z-.965
N45 X5.563Z-1.109

and then I tried:

N26 Z-.645

I can't seem to get around this one and probably missing something really easy....

Thanks in advance for any help...
