That is so predictable, I don't allow my students to have a scriber in

Yep. When my uncle was working on aluminum airframes, they were VERY
careful to not even scratch the pieces if they were replacing.

Aluminum is a great material for boats sometimes. My old 18' Grumman
canoe is 47 yrs old and in great shape. It weighs much less than most
smaller boats. Whenever I go with kayakers, they are always amazed
the humongous canoe weighs so little. It did require repair once when
it got lodge under a tree on a flooded river and the Al tore. Got it
welded and it is almost as good as new.



"When my uncle was working on aluminum airframes..."

Now *that* is a laugh...a relative of loogy holding down an actual job.


It was one of those prison training programs.
