well said time served chippie myself involved with local authority minor works dept mainly doing new build, refurbs ,door fitting, lock fitting contracts.
in the latter years due to competive tendering forced onto maintenance

puttting other contractors work right.
lost count of how many pbs1's fitted ,mortice locks fitted, 3part multilocking systems by fullex,Yales fitted by hand in them days none of the fancy lock jigs or battery drills.
myself moved into the callout industry with the corpo getting called out all hours super glued locks in multi storeys 20th floor 2.00am bloody lift broken,the lovely smell of urine cabbage i could go on for hours like uncle albert talks about the navy

.
having the right tools the patience and the commitment of doing a job well done.
22yrs and still learning everyday moved into lock opening six years ago brought a set of picks to broaden my horizons mica to slip the yales etc.
various crime waves have dictated our way forward into lock opening and with the internet the tools available now make it almost childsplay, but you do have to have the knowledge of how things work hours of stripping down locks defeating its mechanism gives me the same satisfaction as fitting a door or boarding a window to facing with putty.
once you have the dedication and care you can turn you hand to almost everything, still get that adrenaline rush when phone rings at 3.00am ready for the challenge ahead.
