To hold the locking nut into positon and to stop it sliding back out a smaller holed rod is pressed fitted and glued.
The over hang will be trimmed away to sit flush.
Next it to make the outer "keyed" cylinder.
This outer cylinder will house the Spring, so it needs to be plugged and glued.
The spring can now sit inside of the outer cylinder
Using the long clear screw the assembly can be screwed togther.
The movement is smooth and slides very well. Next i'll add the Micro switch and attach the unit to the fron of the case.
