Help: CGE Tripod Legs and "T" Bolt w/ Spring!
Posted 29 August 2009 - 08:06 PM
As you may know, this is a poor design with a "spring" that screws into
the female threaded housing, providing the proper diameter for
the "T" bolt to screw into to hold the leg in position. The spring
screwed out with the T bolt and I cannot get the warped spring
to go back into the housing to allow this "rigged" system to work.
Can anyone provide a solution?

the female threaded housing<<<
It may not be a poor design, just poor execution. Coil inserts are more costly and time consuming to use than simply tapping the native metal and are used because they are stronger and wear much more slowly than threads in soft materials like cast aluminum.

I worked on a project where an engineer decided it would be a good idea to use Helicoil inserts in all holes tapped into aluminum. Nice idea except the 304 stainless steel inserts would gall with the stainless steel screws. Poor execution. For a bit more money we switched to Nitronic 60 Helicoils and the problem was solved. Later, we eliminated the inserts and tapped directly into the aluminum as the alloy was strong enough and the fasteners were not intended to be routinely removed.
