How would a little adhesive soaking into the wood affect anything?

    Question for those who are in the habit of laminating up new bridge roots - or maybe even those who don't, but might have some thoughts to share. I just completed building a bridge root for a customer that came out very nicely, but the overall curve of the bridge is off by a couple millimeters or so, much like other ones I have built in the past. I really don't understand that. 

    One would think of the possibility of some small spring-back effect (but with 18 laminations?), but the curve error is always toward a tighter curve. How can that be? 

    I don't think it is a significant issue as you can easily correct the bend with your pinky - but still, how does this happen?
