We cut the wires and disassembled the clamps to check how much adhesive went into the gap and onto the wire.

• We confirmed the adhesive cured by examining the remaining portion.
• The clamps were easy to separate despite the adhesive. See this video.
• The adhesive did go into the grooves and around the wires. See this picture, for example.
  • Deposited adhesive can be seen clearly in the right wire. See this picture.
  • The left wire did not seem to have kept any adhesive on but its groove did. See this picture again.
  • The flat component of the clamp has marks where the wires were. The marks look like adhesive and not like scars. See this picture. We have to scratch to make sure they are not scars.
• For the right wire we deposited a blob of glue around the wire at bottom face of the clamp and then smeared it and cleaned the excess with the rubber spatula.
• For the left wire we deposited glue far away from the wire and then pushed it towards the wire with a soft tool.
• It seems the method applied to the right wire got more adhesive int the groove.
• Adhesive also went into the gap at the left side of the clamps. See this picture. As a test, here we applied the glue with the tip of a teflon needle and smeared it with the rubber spatula.
• No blob of glue was created around any of the wire at the clamping points.

The test was successful in the sense that the adhesive went into the gap and the grooves around the wires. However, I wonder if this tiny amount of glue would keep the wires in place.

As information byproduct we learned that the scars in the outer locating clamp are rather superficial. We have the impression we can reuse them. The ones we tested were removed once and put back again. In both cases the screws were tightened with a torque of 2 Nm. See this picture. The tungsten wire was not damaged. See this picture.
