Glue as Repellant

The sun has been warm and the days have been long and while I should be staining the snot out of some shingles, I've found myself working on my real-life house more than may wabi sabi house.  However, I'm picking up where I left off--the front porch (or lack thereof).  The assembly of the porch posts seems to be as challenging as getting all of the railings straight in my earlier porch work.  (If you remember, readers, straight railings were but a dream that was not actualized.)  Each post is comprised of four pieces.  I have found that maintaining some sense of accuracy is possible until I apply the last portion.  That's the moment the glue decides to act more less like an adhesive and more like repellant.  Everything exact goes out the window (or off the porch) and in that moment when everything is slightly off the glue finds a permanent bond.
