Hey Bobby, To get the spray glue off of the wood just wipe it down with a rag soaked with mineral spirits. that will take the glue right off.
Here is a little trick on making tight inside cuts. Actually, there are two. If it's a 90? turn, cut just to the corner, back the blade out just a little, then widen the kerf with the blade wide enough to turn the blade without binding. Second tip, If the angle is sharper than 90?, cut to the corner and just a smidgen more, back the blade out just a little, turn the blade with the teeth into the blade, then back the blade back into the corner. then just line up the blade and go!
