    Thank You Tex !

    That makes a lot of sense, especially the way you explained it. That explains why the wrap-around air scoops were deleted prior to the operational launches. They probably would have only increased drag and weight.

    I love the detail, can you provide a bit of instructions/tutorial on exactly what is
    the "dry brush "weathering" technique " and how you did your F1 engines?

    Dry Brush Technique "How To"...sort of.

    It's really simple. You start with a stiff brush, dip it in thinned down water based paint then blot out the excess (photo 1). The drier the brush the better the result, hence the name.

    Holding the brush at an almost upright angle to the surface, LIGHTLY pass over the surface to be detailed moving in one direction only (photo 2). At the end of the stroke lift the brush up and make a second pass. It's better to start moving then make contact with the surface then lift the brush from the surface while moving. The idea is to not stop, also it is important to make sure you apply VERY light pressure.

    Hope this helps. If you have any other questions please don't hesitate to ask. :)

    Yup, that's exactly it. I used to do this alot on my p*****c models to add realism... never thought about doing it to paper ones, though! :-D

    Carl, I'm planning a trip to the Cape me too the last week of july. I'm Italian and some hint from You will be very useful.
    It will be for me a pilgrimage to the Moonport and I would like to take the maximum advantage from this trip.

    Thans in advance,

    Thanks for the new technique! I would've never thought of that. The effects are great!

    Hy, all friends of the SATURN
    Hy, Greelt

    The modification on the internal cone of the F1 engine looks great,
    but I think it should be a lot darker.

    I also started with my first F1-engine and I made a little modification:
    I added rings to the outside of the cone.

    Looks Great!

    Have You done all (5)?

  17. Ewald Haruksteiner

    Hy, Carl

    No, at the moment I made just this one.
    For the future I'm planning the hole Saturn V
    (I'm waiting for Greelts next work).

    The rings were done by two layers of 300g/m² lightgrey paper.
    After the foto was done, I added a third layer and
    drew the little clamps with a fineliner.
    It's all a test. The final work will be more accurate.

    The rings look great, you're thinking along the same lines I was. I have yet to modify the engines, I jumped ahead and mounted them. They can still be worked on it's just going to be a little harder.

    Great work!!!

    I haven't starte building, but was wondering when someone would attempt the rings. Ewald, you did a superb job. Very detailed. Sehr Schon.
