How many times have you gone off in search or to get this or that?...
Hunting for random tools multiple times in the middle of the job is a big time waster.
A even one dollar per minute how much did you spend?
No big deal. 60 seconds or 30 seconds or 3 minutes here or there. It adds up lost income.
Simply moving a rolling tool box from one place to another spot costs real money and is bad.
Yes one has a lot of duplicate tools which seems silly. It pays for itself and plus. All those wasted seconds add up.
Watch the pennies carefully and the dollars will take care of themselves.
Arms reach, 2 to 4 steps max is a theory I believe in.
I have 3 triple stack Kennedy boxes that are mine alone with the label "touch these tools and die". I should only have to go to them very rarely.
I firmly believe that all the stuff you may need to setup or run should be employer provided and organized at that machine.
If they have to go to their own box I did something wrong.
