[AT] 39 Farmall A coming along.....

[Al Jones]

I was wondering if plastigauge would be needed to double-check stuff when it 
goes back together.  I gotta get a copy of Spencer's engine overhaul 
book.......

You are correct, this is sort of a side project.  I have about 5 students 
that are really eating it up.  Before it is over I intend for all 24 
students to have played some role in it.  Basically when they are finished 
with what I am actually grading them on, (basic electricity--they have a 
test on the unit Friday) they can work on the tractor.  They are all fairly 
proficient with hands-on type stuff so it works well to keep them busy.

A lot of people don't realize it but career-technical education (formerly 
vocational) classes in NC public schools have an end of course test just 
like the "academic" subjects.  We have to make sure the students get the 
core curriculum (in other words, what they will be tested on) first.  I will 
keep my opinions on how the system is run, at least in NC, to myself.
