    I can't help it this time but I just had a really good laugh.

    This quote from our new member, CaptainEqs is what did it.

    He tries to prove his point with a book published in 1953 (a time when most aircraft then in the air were made with FABRIC and WOOD), then he disputes the very same company which wrote that book when they list 6061 as an "aerospace aluminum" on their website.
    I guess that pretty well settles how much he knows about aircraft, never mind what they are built with.

    That is my last word.

    Yea. Remembering WW II very well I had to laugh at that too.

      Who cares if the HSM typically learns that some 2xxx and 7xxx aluminums might be referred to as "aircraft aluminum," regardless of what some parts of planes are made out of.

      I want to know what is considered "aircraft wood".

      Edit: Actually, aircraft fabric is probably more interesting nowadays. I saw something that said the plane upholstery industry is extremely cut-throat, since weight savings can be tremendous.

          "...aircraft wood.." ?
          Well if the name of Howard Hughes' experimental plane is an indication, it must be spruce.

            You opened a whole new thread after Neill locked the last one, just so you could get the Last Word?

              Of course he did,How long have you been here?

              It's nothing I wouldn't have done.

              But While we are on the subject of IDIOTS, I am subbing today for another teacher who I do respect.
              Keep in mind this is getting to wards the end of the quarter, He has been in a beginning Machine shop class for 8 weeks, 2 days per week, 3 hours per day.

              And he still couldn't read a caliper!

              Till today, I took Him aside and we did caliper training for 2 hours,Man was he pissed he couldn't work on a machine.

                Deleted. Never mind, probably a good one to stay out of.

                  How can a guy last 8 weeks in a machine shop course and not read the calipers? Seems it would be hard to complete any projects.

                    In the later '30's "aircraft wood" was a serious concern and carefully written standard were promulgated. Wood and fabric control surfaces in military airplanes were present even after WW II. The EEA in Oshkosh WI is a repositiry for this old lore. Lumber for aircraft construction is carefully selected for species, grain orientation, dryness, etc. Aircraft plywood is in a class by itself rivaling aluminum for strength to weight as a finished structure.

                    One only has to consider the famous mosquito bomber of WW II capable of near sonic velocities in a dive and it was of all plywood construction. Since it was mostly wood, radars of the era could not detect it except as close range.

                    Materials have improved over the years but no-one should scoff at the original composite - wood - as antiquated and obsolete. It merely has properties that render it unsuitable for modern aircraft construction: heat tolerance, fire hazard, water absorbtion, and rot and fungus susceptability. And it grows on trees whicjh are self re-producing. Aluminum and carbon fiber have to undergo considerable refienment from raw materials before they are ready for manufacture.

                      I make all my planes from paper.

                        ...probably paper made from spruce trees.

                            And a lot of Plywood, may be some spruce in that.

                              Most radar's today would still have trouble seeing them, if not more trouble. Modern stealth aircraft can be seen better by older obsolete radars, they tend to use longer wavelenghts.
