Re: 070214 MMDigest, Rebuilding Parts Damaged by Hot Melt Glue

Hi All,  According to the American Piano Supply Co. catalog, the hot
melt glue sticks I am referring to was the only type that they sold.
It was called "Thermogrip Hot Melt".

According to the box of glue sticks that I got from APSCO, the Black &
Decker part number is GS12.  Digging a little deeper at Google, I found
that this particular type of glue stick works best with the Thermogrip
209 glue gun.  Digging a little deeper, I found a product manual for
the gun.  In the manual, it says that the tip of the gun can reach 390
degrees.  (I was told some years ago that the glue comes out at 450
degrees, but I guess that was not correct information.  Wish I had a
high temperature thermometer.)

Getting back to the glue sticks, the color of the GS12 sticks are a
very milky, almost pure white.  It also says on the package that the
temperature of the glue reaches 380 degrees.  I don't know if it's of
any significance, but the copyright date on the box is 1990.  Whether
this is enough information to determine the type of glue I dealing
with, I don't know.  However, I do know these things for sure; The glue
on the air motor smells, feels, and acts just like the glue sticks that
I bought from APSCO back in the mid-80's.

(That was before I learned about using hot hide glue, from Art's book,
and after learning about white and yellow carpenters glues that were
'recommended' in Larry's book.)

As I have admitted before in this forum, there was a time when I used
hot melt glue in my rebuilding business.  And, chances are that I'm now
paying the price for believing the comments in the APSCO catalog which
claimed, "The fastest and best way to glue wood, leather, metal, felt,
plastic, pottery."  It also says, "the bonds produced are often stronger
than the materials joined."  And that, my friends and colleagues, should
have been my warning sign:

  "Do not use this product to assemble things that you might have to
   take apart at some time in the future.  You have been warned!!"
