Gloomy with No Glue Gun

Last night I spray painted a bunch of my driftwood white.  Grabbed a larger piece than painted letters some vibrant colors.  I started gluing it all together then the crises hit, just as I got to the H in the word Faith.  Just was not squeezing out the glue and the handle wasn't working right.  Argghhh!!

Tonight I tore the gun apart and tried to figure out the problem. There was some hardened glue I removed then a spring fell out.  I then spent 30 minutes on line trying to figure out where that damn thing went.  No such luck.  So now I sit here with a project 80% done and no device to finish.  Just might be time for a new glue gun or my weekend will be ruined!
