Injecting steam into a dovetail neck joint, through a small hole drilled in a fret slot, helps loosen the glue for neck removal. Our Neck Joint Steamer hose assembly will help you direct the steam directly into the neck joint. It has an extra-long 3-1/2" x 5/64" injector needle, insulating rubber handle, 1/4" hose rated for heat and pressure, and hose clamp for attachment to a pressure cooker or other steam source (such as a espresso/cappuccino maker). Steam source not included. This product is made exclusively for Stewart-MacDonald by Brown's Guitar Factory.
