    There are so many books out there that would rate as excellent to someone but would be utter cr*p to the next person. A good book is, only, a personal feeling that can in most cases not be transferred to another person.

    To state my favorite books, I´d have to start with Ernest K. Gann and Fate Is The Hunter. It is a book that has been on my bed time table for almost 15 years now and is well and truly worn – I´ll need a second copy before long! It is such a gripping description of the live of an aviator in times gone by, that it is nearly impossible to put down. And we airline pilots think we have it bad to day!!!:eek:

    As for Richard Bach. I think I´ve got his complete set of novels on my shelfs, and my personal favorites are Gift of Wings and Illusions. But I´ve got to admit that Jonathan Livingston Seagull features quite regulary on my reading list:eek:

    For non-fiction it has to be an Icelandic book called Dansað í Háloftunum, which I believe was also published in English as Dances in the Skies. It is the autobiography of the only Icelandic pilot to fight with the RAF from 1941 until 1945. His after the war years were covered in another book called Flugskírteini 13 and that was also published in english as Lucky 13 and was just as good as the first one

    And the book that got me where I´m now? That has to be an Icelandic translation of a book that I´ve no idea of what was first called! In Icelandic it was called Flugvélabók Fjölva. It was published in Iceland in 1973 and the authors/editors were Rota Marco and Enzo Angelucci. The book has drawings/paintings of 1000 aircraft from the Wrights up to about 1960. It was given to me by my granny when I was 10 years old and over the years it has been gone through pretty thoroughly and is now falling apart with VERY dirty and greasy pages! Problem is, I can not replace it, as it is now unobtainable! My original copy now has a pride of place on my bookshelf, and is rarely used because of it´s rather fragile condition!

    The question has to be: Is this for an airworthy job or just a static?

    If for airworthy standards, I´d say recover the lot and THEN paint.

    If for static, sand the existing paint down (600 wet paper) and then paint to your liking with two pack auto paint with an added flex agent!

    I think it might be difficult to produce an hour long program around a wreck today, as in many cases there is not at all that much left to keep the general public interested!

    If, however, you would like to feature a wreck where not a lot is left, but the crash of that aircraft had a very great impact on the history of of the world, you could not go far wrong by featuring the crash of the B-24 that killed General Frank M. Andrews – at the time he was the commander of all U.S. forces in the ETO and would probably have been nominated as the Supreme Commander of Allied Forces for the invasion of mainland Europe. His replacement as commander of all U.S. forces in the ETO, General Eisenhower, ended up as the Supreme Commander of Allied Forces and later became a President on the back of his wartime service. The what if would be, if this crash never happened, would Eisenhower have made President? Would the invasion of mainland Europe have been handled differently?

    This wreck is in Iceland and there is not a lot left! An undercarriage leg and remains of engines along with smaller items. The crash position is well known to those that want to know and is not difficult to access.

    The glide ratio of the C-152 is very similar to that of the C-172, at around 1/10. The C-152 has a smaller wing that the C-172, so even though it is lighter, the glide ratio remains pretty much the same.

    All of the US manufactured, traditional, GA aircraft seem to have glide ratios around 1/8 (Piper Tri-Pacer) up to around 1/10

    I think you also need to include the lower landing speed of the Spitfire in the discussion. I do not have the hard numbers at hand, but at the back of my head I seem to remember that the landing speed of a Spitfire would be around 20 MPH slower than a Mustang.

    If anyone has the landing speeds it would be nice to have the exact numbers.

    Proctor,
    With regards to going for West System, be very sure of your countries regulations. I´m confident you can use the West System easily if you are happy with your Proctor being Experimental Category only, as West System is NOT certified in any shape or form anywhere on the planet. It is purely to be used on experimental aircraft. If you are happy with that, I personally think it should be the glue of choice.

    Regarding the amount of dope to put on Ceconite (or S****) is very much alive here as well:eek: The camps seem to be split about 50 – 50, but I personally go with the weaves showing camp!

    With regards to painting Ceconite, in my experience, everyone should steer clear of the paint products offered by the various producers of covering. It will always crack along longerons within matter of months. The quickest was 6 months on Piper Cub TF-KAS. And that was not because manufacturers recommendations were not followed, as our painter followed them to the T! To get good quality finish use normal, readily available car paint mixed with commercially available flexing agent. If unsure of the mixing portions, contact the producer of the flexing agent and you will get an accurate data.
    It is difficult to argue the point over the internet. I know about a Cub that was painted in 1985 with the car paint method and it still has not the slightest evidence of paint cracking. Looking at that aircraft and TF-KAS that started cracking after 6 months was all that I needed to be convinced!

    If you want to test the theory, make two wooden frames of 50cm x 50cm and cover them using all the manufacturers procedures. When it comes to painting, diverge. One frame should be painted with paints supplied with the covering process, and one frame should be painted with normal car paint with flex agent added. When well dry, cut from frame and place in your freezer. After being in the freezer for about two days, take them out and crumble them. The one that will crack more easily is inferior, and in my experience it will be the paint process supplied as a “kit”

    If you are using Irish Linen or Grade A Cotton use only coloured dope for colouring, it will do the trick with some risk of cracking!

    Proctor,
    This is well and truly a thread creep, but what the heck, it is interesting!

    The resin as such does not have a temperature restriction, even if it gets a bit gooey at around 10° C 😮 I´m mainly using the West System 206 slow hardener which has a lower “recommended” minimum temperature of 16° C for maximum strength. So far I´ve not have any problems with it as my hangar/ workshop is usually at around 20 – 22° C by means of thermal heating (year around:eek:).

    When you say you heat your glue to approx. 40° C, do you see any change in the apparent strength of the joint as opposed to leaving it at room temperature (approx. 20° C)

    Proctor,
    I´m not familiar with the glue you are using on the Proctor. Of course there are numerous epoxy glues to choose from, but the ones most widely used in aircraft construction in this part of the world seem to be the West System and the older T-88. I´ve tried to use both the West System and the T-88 and for some reason I just like the West System better. Probably just a personal thing.

    I´ve been working with West System on various projects for about 15 years now, and am very happy with it. Of particular interest to me now, is it´s adherence to cleaned up joints with old Casine (how do you spell that??) glue. On test examples, I´ve got a perfect glue joint even without cleaning up the residue of the old glue, with the glue being stronger then the wood. I would again like to stress that this was done on TEST examples, the airworthy joints are all cleaned up! But it never the less gives you confidence to know that even without cleaning, the joint would be strong enough!

    If something is to be done up to airworthy standard, it should ONLY be covered with Ceconite (or equivalent) IMHO.

    Where is the debate about using epoxy glues (is it next?).
    cheers

    Don´t even get me started on that one :dev2: West System rocks and is the only thing I would use.

    Waiting to be shot down! :dev2:
