I spend all weekend trying to make 350 of these parts... They are 1/8" by 1/8" with a notch cut in them.. +- 0.002

Man.. I want round and round... .. can make 25 of them at once... but time after time 25 were not
within tolerance... I must have made a few hudrend before I found out that the 1.5" aluminum plate
that my vise was bolted to was somehow moving durring the cutting. ????

I removed the jig plate.... bolted the vise directly to the table and that fixed everything.
Now I can hold +- 0.0005" and I still dont know what I am doing.. hhaah
