Solder Tape is heat resistant (but will burn under direct flame) and can be used to bind parts together while soldering. The tape will withstand temperatures in the soft solder range (no brazing). This product is a hit wherever I demonstrate it. Imagine holding a lip plate or rib in place while soldering. It doesn’t leave the marks like wire, and is more flexible than clamping. Hold keys on saxophones while soldering adjacent posts and guards. Hold trumpet bells and leadpipes in place. Great for all mounting work. 131004 binds to itself, so you must wrap it completely around the horn. 131005 has adhesive, so you may tape a part to another. Visualize taping a thumb ring to a tuba bell.
