   Probably not.  Your glue line should be about .002 or .003" for best results.  .020 is a petty fat glue line, about th thickness of 5 sheets of paper.

   If we have to account for glue lines in 1000ths of an inch to come out to a specific size them I think we shouldn't be working wood. Would it matter if your top measured 38-1/4"? or 37-15/16"? or 38-1/8"? Why does it have to be exactly 38"?

   It needs to overhang a 36" wide kitchen island by 1".  24 boards of 1-9/16" each leaves only 1/2" overhang; not enough to produce a pleasing shadow line. Adding a 25th board makes the width 39" Which results in an 1-1/2" overhang. I'd agree that an eigth is no big deal, but a half inch is a lot; even for a frame carpenter.

   Why not thickness all the boards -1/32" and add the 25th board?

   On second thought, why are you running your boards through the short length. It may be more pleasing to see the boards running the length of the top rather than the width. Then cut the top to the size you want.

   How close are you measuring the 1-9/16". You may be oversize.

   Epoxy can give you a wider glue line.

   nope

   my minimal 20 odd years of experience is to generally laminate oversize, and saw down to size.

   Even if you is so imprecise to be off 1/64th on each piece, you might be off 3/8 " in overall width.

   Ergo, laminate wider, and trim down.

   Way cheaper than having to add a piece after the fact, and waiting for the glue to dry.

   Besides, with that many pieces, you may find that after glueing and clamping, the sides ain't straight or parallel, and you gotta machine it true.

   Just my observations, sometimes the two bucks of extra wood involved can save 40 or 100$ in additional labour.

   If your glue up adds up to 37 1/2 and you put it on a 36" island that leaves 3/4 over hang on each side. New math?
