I have picked up a Stanley hand drill 5803 but the pieces inside the chuck assembly that grip the drill bit are all loose. Possibly one or more of the springs have snapped through age. The chuck is solid enough to prevent any removal of the gripping pieces, yet they must have been inserted somehow? I hope someone can tell us how to either remove the gripping pieces inside the assembly or where I might get another chuck assembly please. The action and the condition otherwise are great, worth fixing,
