CAD for simple 3-D metal & wood projects?

Same goes for the AK-47.

It is one of those spirals, that each improvement in one area, eventually chases around until you are back where you were, wishing you had a "better" one of "these" to take advantage of the new and improved other thing. The invention of "tool steel", then tungsten carbide, then ceramics, all let more material be removed per pass, but after a while, the machines are too slow, so you need faster machines (meaning bearing, among other things) and more rigid machines to keep the cutting edge where you want / need / expect it, and then "better" measuring devices in order to tell the difference, and so on and so forth.

He's lucky he had sticks. All we had were the rocks and sand. Rock/no rock. that's all we had.

Company I was at for a while, one of the guys pointed at a part, sitting on the floor. It was right at the minimum of the +/- tolerance. As this was a part which would be under a lot of pressure on a ship at sea, the company and the customer were going round and round as to whether or not it met the spec. Good news: they weren't going to take it out of Jim's pay, as it was twice what he made a year.

Probably over in the hard metal's side of the house. But then again, I was just knocking out Aluminum stuff in a high speed production shop.

As the watchmaker's apprentice said when seeing a 1/4-28 tap "My God, I didn't know they made them that big!"

I don't know if that is still a problem. I heard it around 1982 in regard to memory chips. There were resistance test patterns scattered around the wafer to measure the degree and uniformity of the doping level, looking like this:

The wafers we salvaged from the scrap bin at Unitrode had ink dots on the rejects and I don't remember a recurring trend to them, or resistor cells. When I had to test samples on an experimental wafer I practiced my probe setup at the edge to avoid wasting good parts.

Far be it for me to criticize you Leon (you do good work) but I just can not visualize you in a Camry. ;)

But your point is well taken.

Reminds me of a job I did years ago. I was working with corporate publications and was hired to figure out the best way to send out publications to a select group that needed updates on a semiregular basis. I checked out several types of binding and distribution. My conclusion? 3 ring binders! I got them in contact with a source to make them up some binders and dividers.. And it was a success. They just copied the material on 3 hole sheets and sent it out. Simple. And better than any other alternative. Simple trumps complicated crap every time. Particularly if it gets the job done quick and easily.

But we LIKED it!

LOL, Then picture me on a Maserati. ;~) Actually a 2012 Camry SE V6 and 07 Tundra.

Leon, you need to come check in at ToyotaNation(dot)com forums. All the cool kids hang out there.

Ah, so neither Boeing or GE use 3-D modeling to design airplanes or engines. They hand draw anything that requires precision. Got it.

Absurd. You *clearly* don't have a clue.

The measurements may be, but climatologists know the rate of global warming to a tenth of a degree.

Makes for much more sensationalism when graphing and discussing rates of change, akin to measuring crude oil spills in gallons, instead of the standard unit of barrels.

I know you did. And it scared all your neighbors away!. :)

ROTFLMAO!

No kidding I just read, and it has to be true cuz i read it on the internet, that scientist have decided that we in north America and in Europe we are headed doe a mini ice age. Apparently the SUN, that's right THE SUN has been causing the earth to get warm! Well apparently the sun has been falling down on the jolately, maybe the people working for Al Gore gave up. The sun has had much fewer than expected sun spots and as a result we are going to experience colder weather. I always called the global warming thing summer.

Anyway how are we going to be able to afford changing things here on earth so that the sun is not affected, which in turn keeps us from turning into an ice cube???

Bzzzzt ... Gotta be teacups, or the granularity is off. LOL

Traceable to NIT?

Sorry. Old news.
