As a boat building apprentice myself and other newbies were often sent to the stores for things like
A short stand (sorry laddie, none left but try again tomorrow)
A long stand (just wait there laddie, I'll go out back and find one...it may take some time)
A packet of sparks for the angle grinder
Left handed screwdriver
Tin of elbow grease
One or two poor unfortunates fell for the foremans favorite...they were told to sweep all the wood shavings and loose chippings in the yard down to the waters edge at low tide...so that we could gain another half hour before the tide came back up the slipway.
