N19 Soldering Clamp
This clamp is designed to be used with the largest tubas as well as small instruments. Its distinguishing features include a threaded shaft that is long enough to eliminate the need to disassemble the clamp and reverse the slide, one bearing pad that rotates to give a solid bearing surface when soldering nonparallel tubes or tapered bells and tubing, and a bearing pad that can be adjusted up or down to compensate for different tubing diameters or placements that are being clamped. Although this clamp is designed to be used with larger brass instruments it will provide excellent solder clamping for smaller instruments. Note that the bottom of the heavy-duty slide fitting has been tapered to allow fitting between slide tubes when necessary.
