I've told this before when I was Junior in high school the metal shop got a surplus 3 axis CNC mill that was missing the controller. The metal shop teacher thought he could make it into a manual mill. One quick look tole me no way in he-- that was going to happen as it was designed as a CNC mill from the ground up. I found a set of manuals for it long enoungh to see the controller could be built as a project for the Vocational electronics class. The electronics thought it was an excellent idea as it would allow the metal shop to teach CNC operation which in the lat 60's was a rare and valuable skill then. However the metal shop teacher was dead set against it. 6 years later a friends company picked up mill surplus from the school district, A friend built the controller with a little help from me as my work allowed. 20 years later it was still making chips & money even though they had lots of newer CNC equipment also.Bigshu,
I have been saying the same thing for years. I am going into my 16th year as an educator as we report back to the classroom tomorrow morning. Of all the graduating seniors this year, just 12% will go to a four year university. Of that 12%,, just 6% will go on to graduate.
That leaves 94% of all graduating seniors across the U.S. left for the skilled trade occupations. The system I am employed in and any other system where I have worked cram the ACT test down these kids throats. One would think that if only 6% of the graduating seniors are benefiting from the free AACT tests and the free ACT test prep courses they accommodate the kids with that there would be more four year graduates.
All of our resources go to the ACT test. They have sold a lie to our students telling that they have to go to a four year college to make it in life, which is complete B.S.
I cannot for the life of me understand why we don't have metal lathes, press brakes, CNC machines, and the like in our shop classes since the overwhelming majority of kids are going into those career fields is beyond me.
The high school I am currently teaching at and have taught there going on 7 years now, has had the same welding , carpentry, and agriculture teachers in place. All the welding classes do and I kid you not, is take a scrap piece of steel and practice running beads. That is it.
The carpentry department is not much better. All they do is let the kids make a name plate out of a wood blank using a router and stencils. Makes me sick.
I don't know why the ag classes can't grow food and let the harvest supplement the lunches they feed these kids. The lunches are so bad even though everybody eats for free these days, that I would not feed my dog this food. It is that bad.
I suggested to the carpentry teacher that they should purchase a Wood Mizer re-saw machine that allows you to take a log and turn it into dimensional lumber but I guess since it wasn't their idea they just made every excuse for not doing it. They have money in that department too.
I am writing a grant as we speak for free fruit trees. I want to plant Satsuma, pear, plum, fig, lemon, and any other fruit tree that will survive here in the south all around campus so that when they mature and start to produce fruit, the kids can get a healthy snack right on campus.
The trades department has more money to work with than any other department. The problem is our shop teachers have gotten complacent and they want to avoid doing there job of teaching kids skills and how to survive.
It is very disheartening to say the least.
Right, they know how to program a tool, but not how to use a hand tool. I get that it's the same thing as replacing drafting with CAD, but something is lost when you go from spending a few hours shaping wood or metal to doing something else for a few hours and coming back to pull your finished part off a machine build table.But we do have kids who can make things on a 3-D printer and a home CNC mill.
Probably liability reasons. I remember the days where you'd always see at least one shop teacher missing a finger or two.I cannot for the life of me understand why we don't have metal lathes, press brakes, CNC machines, and the like in our shop classes since the overwhelming majority of kids are going into those career fields is beyond me.
It's profitability, .. or the lack of .. "spending a few hours shaping (whatever) .." those hours, .. who's going to be paying for them? A hobbyist is absorbing the cost, knowingly, or not knowingly, .. or doesn't care.Right, they know how to program a tool, but not how to use a hand tool.

We're already going from being builders to being assemblers. If the next step is watching machines make the parts we assemble, we just cut out the jobs of the folks who make the kit parts now.
Exactly, from several perspectives. We can't have it both ways, grieving for the loss of skills and abilities, while at the same time wanting faster, cheaper stuff. I think this came up in the last year or two as something to do while in lockdown for the pandemic, but I like to recommend people read Shop class as soulcraft.. Great book about the value of doing things by hand.These technologies are a tightening noose.
1971. I'm in 10th grade shop class at Northeast High School in St Pete Fl. After brief instruction, my teacher watches as I use the table saw. When I finish, he asks why I was so nervous. I tell him about our 8th / 9th grade teacher at Meadowlawn Jr High next door (Yeah, they're called "Middle Schools" now). That teacher was always telling horror stories of kids cutting off fingers, etc., and had half his students scared to death of the power tools. Mr. B (10th grade teacher) goes over and royally chews out the other teacher. Safety, and respect for power equipment. DennisProbably liability reasons. I remember the days where you'd always see at least one shop teacher missing a finger or two.
I've ripped a lot of wood with my R/A saw. I was always pretty careful, but did have ONE TIME when a board "launched". It flew a few feet before landing. I was always careful to not stand behind the plane of cut. (our bad teacher had a story of a student being impaled by a board from a table saw - probably B.S. DennisI really hated using my radial arm saw to rip stock. Careful attention can reduce the risk, but there are better tools for that job.
I know it sounds like "old guy complaining" ( I am not that old by the way ) but I still think that new generation is different from us. I don´t complain - in fact I agree that we would be the same with actual technology possibilities. Youngs are different and I don´t think it is their fault.
Available technology is allowing youngs to "consume" extremelly large amount of informations. They spend time online "consuming" Internet content.
But again - that is not their fault. Thanks to Covid we closed schools and we practically let them to stay at home.
Percentually will be same amount of youngs interested in aviation like in past generations, however would be good to attract aviation as sport and interesting hobby again.
About affordable aviation....
Yes, that is a large problem.
In fact that was reason why I joined this forum - where to find better ideas for affordable airplanes than on this web?
At the beginnig I was optimistic - there are existing programs where would be possible to get money for trainer airplane development.
Than I found out that there is a large paradox. Government supports development of training airplane. They already spent millions in aviation projects, however result is .....none.
For example electric airplanes....
Great idea allowing to have low costs for flying hour. However can "normal" club afford it? Low fuel / energy costs are only small part of total costs.
Actually... Piper will spend milions to re-build PA-28 Archer to electric airplane. For milions spent we will have few prototypes. Old draggy airframe with new propulsion And than finally they will offer electric trainer for price much higher than "normal" PA-28.
Some clever aeroclubs will ask for subsidies (another government money) to buy few pces and claim that they are environmental friendly.
Total sum of all money already spent without practical results would allow to make trainig for free for few young pilot generations (or cheaper training for many generations)...
I will probably not be able to solve "affordable airplane" problem.... however I would like to try it. And I would like to involve youngs
Well.... point of my post was to show that government money (money from our taxes) intended to help to develop new training airplanes could be used better.i also see wealthy individuals restoring some WW II warbird and wonder how many hundreds if kids could get flight training with the vast amounts of money that takes.
I guess these are the people that want to sacrifice everything for flying. Still white, still man, mostly over 50. Instead of pouring it into drinking till you fall under table or other activities, you decided to do something with your life. Why is it a bad thing that they are white men? There is always a way to twist the reality and blame your ”unfortunately” on someone else.
