Once you get it sort of right, if required, use a piece of notebook paper to open the secondaries slightly, fold it over if not enough. Each paper piece roughly .035 thick,is about 3/4 of a turn on a 24 pitch adjuster, 1 full turn on a 32 pitch.
I think you missed a zero for your paper thickness. Common note paper is about .0035" -.0040" thick. I use it all the time to touch off on the work piece in the mill and when the tool catches it, you know you are .004" off zero.
