Gibson J-200 Neck Removal

Using steam to remove the J-200's neck for a neck reset.
The neck is glued to the body with hot hide glue which will become
soft at around 150 degrees F.

Step one is to heat up the fretboard extension and separate the hot hide glue
that bonds it to the spruce guitar face.

Aluminum covered cardboard shield protects
the lacquer finish from the iron's heat.

Wet towel on top of the fretboard extension
helps generate the steam required to soften the hide glue.
 Hot spatula cuts into the softened hide glue under the fretboard extension.

With the fretboard extension separated from the spruce top,
wet steam is injected into a small drilled hole in the guitar neck block using a stainless steel tube
that is connected to a Mister Coffee Espresso Maker via a fuel hose
 The steam generates plenty of water that can be seen running out of the joint with
some amount of brown color from the softened hide glue.
 Two minutes of injected steam and the neck slides off the dove tail joint with a bit of pressure
 The hide glue cleans up off the joint very well leaving a nice clean wood surface.
