Claims
- 1. A method utilizing an expandable mandrel for producing a filament deflecting curved guide tube within a casing. having an entry and exit opening, the guide tube being formed of a plurality of contiguous abutting segments which are held in a fixed array within said casing by means of a bonding agent, said method comprising:
- inserting the segments in a predetermined order about the mandrel,
- positioning said mandrel and segments within the casing so that the faces of the first and last segments abut the inner surface of the casing about its entry and exit openings,
- twisting said segments about said mandrel to a position wherein they form the desired spatial curvature of the guide tube,
- applying fluid pressure to said mandrel so as to expand its diameter and thereby hold said segments in said desired position,
- filling the interior of said casing with a bonding agent which hardens about said segments thereby fixing them in said desired position,
- relieving the fluid pressure from said mandrel so as to allow it to return to its original diameter prior to expansion, and
- withdrawing said mandrel from within said segment bores and casing.
- 2. The method of claim 1 further comprising pretensioning said mandrel after it is positioned within said casing.
