    I have taken the top cover off of countless Minolta SRT bodies and finally have to ask if there is an easier way.

    As many know, that red dot above the lens mount hides a Phillips screw that is necessary to remove in order to remove the top. The tiny red disk is not 'glued' onto this screw but, nevertheless, it has been quite a challenge to remove it. I have tried using a bit of gaffer tape to see if that would pull it off. In desperation I usually use a pair of pliers to gently unscrew the screw (and end up getting tiny scratches on the body around the screw).

    Its things like this that cause me to despise Japan for a whole .000001% of the time. Is there a responsible response to this earth quaking dilemma? -David Lyga.

    Amazing response, guitstik: I thought it was but apiece of thin sheet metal. I think that I would be afraid to try but I might think of doing that with enough courage. It really is but a tiny disk, not held by anything but the mere sides of the raised platform of the Phillips screw. Frustrating to remove, abeit simple in concept! - David Lyga

    I have grabbed the whole thing with a pair of needle nose pliers to get it starting to turn.

    Usually it can be turned by hand once loose.

    Once loose the sleeve falls back and the red dot pops out to allow you to unscrew the machine screw the conventional way - with a screw driver in the end.

    Sorry David, irresponsible PWSD on my part.

    Pick it on the edge with a sewing needle. Failing that a pin vise can loosen the screw. The chuck in the vise gives an equal pressure around the screw and has no grooves that can scar it.

    That's OK, guitstik.

    And Mike, that's what I usually do and I have managed to get to the point where 'almost' no scratch results. Thanks. - David Lyga.

    Dip a toothpick in lighter fluid and let a drop fall onto the red dot. Wait a few minutes and do it again then carefully using the toothpick move it around the dot in a circle till it loosens and then pressing on the edge it should lift up on the opposite end. You may have to repeat till it comes loose..

    Lighter fluid will not damage the dot since it is anodized not painted.
