<DIV>I would proceed with caution with this method. By the time
the heat from the heat gun reached the interior of the joint enough to
soften any glue you run a real risk of overheating the finish, causing
damage not so easily camouflaged. There is also the possibility of
weakening the veneer glue joint, when applicable. </DIV>
<DIV> </DIV>
<DIV>It could work, but to my way of thinking there are definite
inherent problems lurking. I'd stick with vinegar, when
necessary. Fact is, in my experience most of the time the bench
has become rickety to the point anyone wants it fixed, most if not
all the joints have been compromised to the point where a sharp blow
knocks each joint apart with little trouble. I use a regular
hammer, against a felt-lined chunk of wood. </DIV>
<DIV> </DIV>
<DIV>As always, there are exceptions to every rule...</DIV>

<DIV><FONT face=Arial size=2>I totally agree with Mark here. I knock
them down with a dead blow or rubber mallet then clamp it up
checking with a square as you go. Using a flat bench top allows you
to clamp the entire assembly down assuring all legs will touch on a
flat floor. The supper glue won't work for long, the bench will soon
start racking back and forth again.</FONT></DIV>
