When I have large pieces to glue I use a hot-box: a large box with nothing more than a 100 watt bulb in it. I put the pieces in it for at least 4 or 5 hours. Smaller items like pneumatics I place on an old heating plate for food. I also use a heat gun for specific places.</FONT></DIV> <DIV><FONT face=Arial size=2>I find that when the humidity is high in my workplace, the glue will gel AFTER it has set. The hours after gluing should be lower humidity. Hot glue will gel in a humid environment, regardless of heating the surfaces. Believe me, I live in Louisiana on the coast. I try to glue in an air condition environment, or on a low humidity day...usually one or two days in October! </FONT></DIV><FONT face=Arial size=2> <DIV><BR>Hot glue really does not depend on drying per se, like other glues. It is a chemical reaction that is AFFECTED by humidity.</DIV> <DIV> </DIV> <DIV>Berley</FONT></DIV></BODY></HTML>
