    The turning effect seems to happen over about 8 to 10 seconds to turn
    the aircraft 15 degrees.

    Once turned it seems to remain stable now pointing in a different
    direction. I then see that the balance ball is a little off centre.
    I did try turning the ruddder trim knob to the right and left but it
    did not seem to have much if any effect.

    Sounds awfully slow and consistent to be weathervaning to me. As others
    have said, weathervaning happens with wind gusts and you'd feel the plane being "pushed" a few degrees left or right as it was happening.

    More than likely it's a coordination issue. Either the rudder and/or
    aileron trim is off, or you're letting your feet and fingers do things that your head isn't paying attention to. You're the pilot, man. Control the
    plane! Watch the ball!

    Steep turns 45 degees or more to the right are fine,
    Have some trouble with turns to the left usually kicks in after one
    full circuit almost if the fluid in my ears is delayed in some way -
    Thogh i fight the sensation and can do satisfactory steep turns to the
    left.
    maybe having just done a few 45degree turns to the right and then
    pretty much banking to the left without stopping at the straight and
    level for a rest may not help.

    Have you tried starting with a left turn? I don't think it's completely outrageous for you to have a momentary queasy sensation as you do the 90* switch (from right 45 to left 45). It doesn't happen to me, but I can see
    how it might be uncomfortable for some.

    Loosing height quickly is no problem the ears do equalise to the
    pressure change - gaining height quickly in a worn PA28 does not
    really happen max = 750 feet/minute thats with just me fueled to tabs
    and no baggage.

    The concept of the short approach is that you're going to be doing an aggressive descent in a 30* bank turn...

    I'm guessing you may have some "queasiness" issues (my sister has them) and may want to talk to your AME about it. I think your "weathervaning" issues
    are really just letting yourself be the passenger instead of the pilot.

    Thanks for that, could well be just me being a passenger.
    The nearest to the short approach sometimes is a base leg join where I
    have to loose 800 feet in a short time and turning. but thats not
    really agressive.

    In response to another poster mentioning the UK weather and costs that
    is absolutly right. weather here has been awful on the south coast and
    the cost of flying
    Hire for 1 hour of a PA28 wet is about $250 at loose approximation US
    dollars
    Landing fee at my local airport is now $35
    Touch and go is $16 and they now charge $16 for a missed approach
    -they waive that fee if ATC instruct a go around,
